Hey Guys, I installed some Buddy Club N+ Spec coilovers a couple months ago. Everything was great and now that I had a new set of wheels and tires put there is a problem. The drivers side rear seems to be about 5mm lower than all the other corners :S So I took the tires off and checked the height of the coilovers and they were the same. So what's wrong with it? Should I just adjust it to the right height or is something serious wrong?

Thanks in advance.

 

I've seen this a lot with many coilovers. I just think it's the design of the car. My KW V3s are the same way.

 

There are only a few reasons this would happen. What were your tire pressures before and now? Are they the same? Also, what about the fuel load? If these variables remained unchanged then the issue is bad spring tolerences. This is a good reason no to use springs made by or branded by venders unless they guarantee the spring specs like hypercoil does.

 

what was your method of "checking the height" of the coilovers?

 

Mods? Exhaust, header, battery, spare tire, and airbox are all primarily passenger side weight.

 

Well the tires on there now are 17/40/255 from stock 16/40/215, tire pressure is the same and I only have half a tank now. I've done no
other mods to it (yet). I checked the height with a tap measure, from the same points on the coilover.

FISH22: did you just adjust your coilover to the right ride height to match the rest of the car or just leave it?

 

If it's off, I'd move it back, generally.

 

I was going to leave it, but I had the car in the air to do a pad and rotor job, so I corrected it.

 

You're complaining about 5mm All suspensions are like that. Spring/shock combo will have a bigger difference. When I first started with Eibachs and the infamous koni yellow combo, my driver front was noticeably higher than the passenger front. My KW v3's were spot on when installed. I did raise it up a bit, so they might be off. 5mm is nothing. The ground is never even and tires can be a factor by wearing differently.

 

Wait a minute, you *can't* have ONE corner low due to suspension. It's a twist in the chassis (possibly within normal tolerance range).

Get the corner weights right and the average front and rear heights where you want them. i.e., if all corners are where you want them but the drivers' rear is 5mm low raise both rears 2.5mm to split the difference.
