How to Lower your car with Coilovers


Hey guys ChrisFix here and today We’re going to take this monster truck looking car And we’re dropping her down to the right height this car should have had from the factory and we’re going to do that using Coilovers now if you didn’t see the last coilover video where I explained what Coilovers are and their benefit as well [as] showed you how to install front coil overs and camber caster plates So we could lower the front of the car and adjust the wheel alignment I’ll be sure to link that video in the description, so you could check it out, but in this video We’ll be installing these coil overs into the rear of the car Which is completely different than the front [setup] and after we get those installed we’re going to get the car laser aligned and then head To the track to really test out this new suspension Now I don’t know about you But I’m really excited to get these in so let’s get started and the first thing We need to do is safely support the frame of the car on jack stands, then lower the suspension down and remove the jack Now before we get started disassembling our suspension anytime you jack up [your] vehicle You want to make sure that you chalk off the front wheels so the car doesn’t roll I like to slide a wheel underneath the frame of the car just [in] case [and] you want to come over here [and] just give The car a good solid shake to make sure it feels stable everything’s good here So we’re safe to start working on the car Now our coil over is a shock and spring combined which means we’re going to be removing the spring and the shock and we’re going To start with the shock and in order to remove the shock we have to put a flight load on the suspension so we have to jack up the suspension just a little bit and the [reason] why we want to support the Suspension is because right now this coil spring is forcing the suspension down and the shock is holding it up if we unbolt the shock The suspension is just going to drop real quick Now that we have the jack holding suspension up when we unbolt the shock It won’t move and in order to get to that top bolt we have to come around back here pop the trunk And get this carpet out of the way, and we’ll remove the trim which gives us access to our bolt This is a [fifteen] millimeter And it’s coming off pretty easily and with the nut removed from the top of the shock We could go from the trunk back down to [the] suspension And then we could follow our shock all the way down to the bottom bolt with this we’re going to need a wrench on one side and a ratchet on the other and Loosen up that bolt and the nut will come right off and then slide the bolt out and Now our shock should come right out. Just like that Now our coil over is going to get installed Right where the shock used to be the problem is this quad shock right here hits the new coil over so we’re going to have To take it out to make [room] for our coil over and this is easy enough to remove there’s an 18 millimeter nut up here Good and a 15 millimeter bolts down here Good and with that the quad shot comes right [out] And we might as well remove that steel bracket that holds the top of the quad Shocking it only takes a few extra seconds to unscrew these bolts. This is actually pretty thick steel So it’s kind of heavy, and there’s no need [for] it [anymore] But I don’t want those two bolt holes being wide open like [that] So I’m going to screw the two bolts in to seal up those holes good and we’re almost ready to remove our spring but before We could do that. There’s a brake line right here That’s going to get pulled on if we don’t loosen it up from this mount right here So let’s remove the brake line holder bolt. Which is a [10] millimeter Good and with that bolt removed that allows us to move our brake line down like that and gives it more room So it could drop the suspension And we don’t have to worry about this getting pulled on and the reason why we’re dropping Suspension is so that we can remove our coil spring now [on] this car when we drop the suspension down We’ll be able to unload the pressure from the coil spring enough that we could take it out safely, and we’ll do that Just by loosening up the jack and letting it. Go down slowly, but on some cars [you’re] not able to do that [even] when you let the suspension down this coil spring will still be under a lot of pressure and In that case you use a spring compressor like this a kit like [this] is inexpensive and well worth it You just want to make sure that you find one that has these safety pins that lock into place [I’ll] link this one down in the description for you. So what you’re going to do it fees You can see how this has a little curve Well you just put that right around the spring and then you lock that pin in place And then you push the other end around the spring and you lock that Into place now do the same thing on the opposite side and you could use an impact gun or a normal ratcheting wrench so both work it’s just a lot easier to use an impact gun and what you do is you tighten down one side just a little [bit] and Then tighten down the other side a little bit and you want to tighten both of these sides down back and forth So they tighten evenly and notice how the spring is compressing And that will compress the spring and make it smaller so [that] you could remove it from the car And you want to make sure that you do this [correctly] because there’s a lot of pressure in this spring right now So it can be dangerous, but luckily in this car and many other cars. You don’t need the coil spring compressor So now we’re going to slowly let down the suspension all the way and just [get] a pry bar in there and pop that to bring out Good and now we can remove this spring and with the coil spring removed We are almost ready to install our coil over but first we need to install the lower shock bracket So we’re going to have to remove the stock bracket so get a wrench and loosen up the nut that holds this in once you Get it loose. You can spin the bracket and remove it the rest of the way like that now Let’s add the new Bracket and start with the top bolt as you can see there’s really not a lot of room to get your Hands in here for the washer so a needle nose Is definitely [helps] with the job? Next we could get the bottom bolt in and it’s a lot easier to get the washer and then the nut onto the bolt so with the bracket hand tightened in let’s put the coil over in the bracket slide the bolt through and hand tighten the nut now we can jack the suspension up and inspect for clearance around the coil over and Already I need to stop because I could see a spot. We’re making contact [so] we’re actually making contact with our bracket You can see the spring seat nut right there is contacting the bracket right up here So I’m going to mark the area that we need to trim Let’s lower the suspension back down remove the coil over and undo our bracket good thing we only hand tighten these So this will go a lot quicker We’re going to need a trim right there and right there on our bracket, so let’s get this in the vise And I’m using a grinder [to] remove the metal we just march on the bracket We just grind it down until the paint’s gone Just like that and since we did grind down this area and remove the zinc coating I want to cover the metal with [some] paint To prevent rust and I’m using a silver paint marker, so it matches the color now Let’s install the bracket get that top washer in there And the top nut good get that bottom bolt in then the washer and then the nut Now we could tighten the bottom bolt down and then the top bolt Good and finally we could get the coil over in and slide that bolt in place and hand tighten the nut And with the coil over in place now We’re going to go and test fit it again And we want to line it up to that hole right up there like that, and then jack up the car all [the] way So the weight of the car is on the suspension So now we could go underneath and take a look and the clearancing. We did here with our grinder worked perfect We now don’t have any issues with our coil over hitting the bracket It’s also a good idea to inspect around the coil over and I don’t see any issues so let’s get up in the trunk and tighten down to the top of the coil over add the washer and then the nut and tighten it down to 60 foot-pounds of torque I also like to mark the bolt and the stud with a black line so at a quick glance. We could tell if that loosened up Alright, and we are almost done. So there’s only one more bolt on [that] coil over that we need to tighten down We’ll do that in a second. I already installed that coil over. It’s the same exact process on both sides So I did that already it’s completely installed now would [be] the part where you put your interior in I have my interior all out here And I decided I’m not going to put the interior back in because I’m just gonna have to take it out again when I go Weld in the roll cage, so it’s tighten down that last bolt and get the car on the ground So the last bolt we need to tighten down on the coilover is this one right down here This bolt connects the coil over to the axle and gets torqued down to 50 foot-pounds Good and our coil over is completely installed [now] We just need to get this brake line back into place get that screw in there and snug it [down] And before [we] put the wheel back [on] let’s adjust the coil over you always want to adjust the coil over with the suspension Unloaded so remove the Jack now to adjust the ride height all we have to do is turn these nuts right here so I make sure the nuts on this coil over are threaded the same height as the nuts on the other coil over so the Right height will be the same next grab your coil over wrenches And then lock them around the two nuts like so and tighten them into each other just like that And that’s a good time to adjust your valving we have 18 clicks of adjustment So I’m going to increase it to [9] which is halfway And then we’ll know if we need to go stiffer or softer from there and with that we are done installing the coil overs So [let’s] get the wheel on torque it down in a star pattern and then jack up the car So we could remove the jacks in Finally lower the car back down and don’t forget the wood under the tire since the car is lowered now And we want some clearance to remove the Jack and the reveal Moment of truth. Oh man look at that check this car out lowered Holy smokes does that look so good I can’t believe it look at that this car looks amazing [now] that is how you install coil overs? So we drop the car two and a half inches in the front and the back The front still needs to get aligned the toe the camber the caster all has to get aligned So we’re going to go do that next and then we’re going to go to the track now I’m kind of curious with it being so low if I’m going to be able to get out of my driveway Here goes let’s see what we get this is the worst part backing down the driveway and not knowing if you’re going to hit the bottom but we’ll take it nice and slow oh, just a little tap and The front clears, okay the front just barely clears I’m definitely going to have to go in and out of this driveway at an angle for now on So I’m on my way to the alignment shop I want to give you guys my initial thoughts on these coilovers And holy smokes what a difference of [are] [I] these things make Now I did set them up so that they are a little bit stiffer for drifting. So they are Stiffer than the stock Springs, and I haven’t really in any turns or anything by it so many pumps And you can just feel every single one of them and you can feel all [the] divots in the road now That’s my set up you can’t set them up to be a little bit softer and feel a little bit more forgiving on the road But right now what a difference. It’s like a totally different [car]. I cannot believe it I can’t [wait] to get this thing aligned right now It feels like it’s aligned pretty good from just eyeballing it But I can’t wait to get it dialed in and then head to the track [lets] get that alignment shot wow Right now the alignment guy is messing with my alignment I asked him to max out the camber and give me stock caster and no toe, and I don’t want to bother him So I’m going to let him do his job From what I saw this guy did a really great job and was real careful. Which is awesome So thank you very much. So with the car dialed in, thank you very much alignment guy. now It is time to get to the track Here goes let’s see how the new Coilovers handle and if there is big of a deal as everyone said Turn One Oh man, I could feel like huge difference already. I was not expecting that at all The car is so much more controllable and predictable turn two Yes, this is awesome And turn three and I think I’m getting a little bit overexcited here So the rest of the event was a blast. It’s basically learning a new car over again would be foil over there There’s no body roll the suspension stiff and predictable and I have a lot more control and more importantly Confidence going around the corner I can tell them hitting these corners a lot quicker than I used to and the car is finally behaving This is definitely something. I should have done a lot doing it as always I hope you guys enjoyed the video and if you’re not subscribed consider subscribing if you are Subscribed we have some awesome stuff coming up so stay tuned
