Alright, here are my specs so far

Greddy Coilovers

ROja 19x8.5 frnt and 19x10.5 rear rims
with 255/35 front and 285/35 rear

i forgot the offsets on the wheels

I want to lower my car to eliminate wheel well gap and also to give me better handling and traction on the track.

I want to know all the specs for the alignment i wanna do.

For example, toe, camber, caster, How much to lower, ect.

Im going to do my alingment tomorow so if i can get all the info today, that would be great.

 

factory spec is the best. maybe give it a more -camber for better handling.

with neg camber, you will burn your tires more quicker.

I got -2.0F -2.4R for the camber and the toe is factory spec.

 

Do you have a camber/toe kit for the rear suspension already? If you lower it much more than .5" you'll probably need that.

That being said, you pretty much can only adjust toe in the front, so you don't have a lot of decisions to make. I would set the front to 0 toe and the rear to .06 degrees of toe. That should help it to turn quick and stay planted when you get on the gas exiting a turn.

If you have camber adjustment, try something in the 1.5-2 degree range to start. Your alignment can affect the handling drastically and your tire setup and driving style affects everything a lot. So anything you read in these forums is just a good starting point and you'll have to tinker with it until it's right for YOU.

 

thanx guys. anyone know the proper way to lower coilovers. I wanna slam my car.What do i turn and what not to turn.

 

Read the instructions that come with the coilovers!

And if you are really concerned with performance more than looks, don't lower it too much. PERSONALLY, I wouldn't lower it more than an inch or so. Mainly to preserve suspension travel, second because the geometry is probably negatively affected when lowered too much. That is something I haven't been able to find a firm answer on yet.

 

i dont have the instructions anymore.

 

If they are double adjustable I believe you are supposed to use the adjusting rings that don't touch the spring seat. If they are single adjustable just raise or lower the collars on the spring seat. For fine tuning (corner balancing) always use the spring seat collars.

I believe that info is correct, but I've never owned coilovers. I just read too much on these forums!

 

lol thanx. i guess i can figure it out. it cant be hard at all.

 

I have the greddy s type on my 03 too. I just raised the front by half an inch and it actually raised it a little over an inch. Adjusting ride hight is not the hardest thing, but also not the easiest. I think I set the rebound off when I was adjusting because it came loose at one point and I had to retighten it.

How do you know if your rebounds are the same on both sides. The only thing I could think of was measuring the entire coilover.

 

I've been reading about camber issues with lowering the Z. I have a friend that has a G35 with a 1.7 drop all around with Time Attacks TE-37's. 19 x9.5 (255/35/19) in the front and 19 x 10.5 (275/35/19) in the rear. My question is, since the G & Z are somewhat similar wil negative camber be a bigger issue on the Z than the G? The inside of his tires are not that worn compared to the outer part of his tire, it's fairly even.
