Thread: gc coilovers

please excuse my ignorance, but will these work on my b13 without modifiying the spring pearch?

Yes, they will work with any OEM type strut. No modification necessary.

However, you will probably have "clunks" if you do not modify the spring perch.

Be careful you do not overlower the vehicle. You have three (3) inches of suspension travel stock.

I actually want to raise it I currently have konis, and road magnets which I think is too low in the rear which is hurting traction when I launch the car.

by modifiying you mean cutting the perch off, and welding a large flat washer in its place?

I doubt that would hurt traction, there is not much weight in the rear, it's all over those front tires anyways.

Do you have Superpro Caster bushings? ES bushings up front? A lower control arm brace (Whiteline or Progress)? Those items will all increase your traction to some degree or another. Also, there are Haas traction bars listed in the Suspension Thread.

Yes on your second question. See this post:

Under Advance Design (aka Ground Control).

However, it you want to raise the rear, you can certainly do so with the GC sleeves over your Konis.

Are the Konis shortened? Just curious, it will make no difference if you are going to dial in stock height or higher.

I have white line caster bushings and ES everywhere else. I don't have a control arm brace for fear it won't clear a 3" downpipe.

I've read the traction bars are bad for handling so I don't want to go that route, because I want to do more than drag race

the front is shortened, but the rear is just put together per konis instructions. for the rear I'm not looking to go stock or higher I just want to raise it about an inch to match the front right now it looks like I have a load of bricks in the trunk

Sounds like you have a very good suspension already.

The GC sleeves would be a perfect, near ideal, answer to your issue.
