Had all the LCA bushings replaced with ES ones by a race shop that specializes in Porsches.
When I was driving back home I noticed the car didn't take left turns as well as it used to. I looked at the car better when I got home and noticed the rear right (passenger) side was sitting much lower than before, about 3/4-1" lower! The tire was tucked into the fender well. Before it had a 1 finger gap between tire & fender just like the left side.

The spring rates are 750lb/in. in the back with Advance Design shocks so I know it's not like the springs are sagging from one day to the next..

I can't figure out what they could 've done wrong. I would guess they had to disconnect the sway bar endlink (Comptech sway/tie combo), then remove the bolt that goes through the shock as well as the bolt that goes into the subframe and tie bar. I wonder if the sway bar got loose and the endlink moved up which would explain the car sitting lower as the control arm was installed higher up? Is there a procedure they had to follow when putting the LCA back on? Like which side you bolt on first, or does the shock have anything to do with it?

I had a similar problem a couple of years ago when a shop installed the Comptech sway/tie bar wrong and the car was sitting too low and it would fishtail without warning. I took it to a Honda race shop and they did it properly. I think they said the other shop installed the sway bar preloaded and it was supposed to have no load on it when it's installed. I appreciate any comments on what could be wrong. I 'm supposed to take it back tomorrow morning but I 'd like to go prepared in case they tell me there 's nothing wrong with they way they installed the LCA. Thanks!

 

anyone?

 

All they did was press in the bushings?

 

After I installed new coilovers and LCAs, it looked crooked too. I measured the coilover settings and it was exactly the same per side. After driving it, it went away.

Just drive it... that's what I would say.

 

it should matter how they install the lca.

there is no steps or numbers in installing it.

it doesnt matter which bolt goes on first.

its just eaiser putting the closest bolt in first while the shocks in place and then jacking up the rear of the control arm and trying to thread it in the hole.

 

I figured out what caused the rear right side to be lower.

This morning I walked around the car once more and noticed the front left side was higher by at least 1/2" more than the front right side which by the way looked normal and just like before. When you raise one corner, you automatically lower the opposite side diagonally accross (duh, I should 've figured this out much sooner).

So I took the front left wheel off to see if my suspicions were right. And sure enough they had installed the fork (the lower shock mount) on the wrong spring perch of the Advance Design shock which has 3 perches. They used the bottom spring perch which pushed the entire shock upwards thus raising the car. I could 've fixed this myself but I figured since I paid good money (they over charged me being a Porsche race shop..) why get dirty and possibly hurt my back again when they can adjust it and I can show them what they did wrong. They 're only 2mi. away.

So I took it over there and had them move the fork up to the top perch which lowered the car back to where it originally was. Sure enough, the rear went up at least 1/2"!

Takoumi: Installing coilovers, ie: shocks & springs is a totally different story. And yes you have to let them settle after you drive on them for a couple of days or 50+ mi. Your car will always look crooked in the beginning after a coilover install, unless you spend some time and lower each side exactly the same (same # of turns on the spring seat, etc.) and even then the car may not have an even drop all around because your bushings wear out differently and some suspension components may be slightly bent or the caster may be slightly different on one side than the other like it is on mine. With a caster difference in the front, I could have the same # of turns on the spring seat to within 0.1mm on both sides, and my car will always have a different height. It's not too noticeable but the difference is there. It's because of the caster problem I 've had for 3-4yrs now after hitting a huge pot hole. So I have to compensate by lowering or raising one side a little more than the other and the car gets pretty even, but I usually do that when corner weighting the car. You have to corner weight when you have a coilover suspension. Corner weighting is not so your car will look even all the way around, it won't, and that's not what corner weighting does. It's just to get the cross weights even and make your car handle better and be more responsive and stable (not snappy or fishtail happy) when making quick transitions and transferring weight fast. Basically cornerweighting makes your car handle the same when making right turns and left turns and don't upset it as much. It makes tire wear more consistent too.
