Coilover kit with Bilsteins or Full Ground control setup?

[Killacortes]

So i wanna drop my car because with the wheels i put on in my car look retarded with it being so high.

any recomendations? i did a little bit of research and how late model e30's rear looks lower than the front so i was thinking of going with ground control coilover kit with my bilstein hd shocks.

or should i just wait and save up for the complete ground control coilover suspension kit?

the only picture i have with wheels are on my sig

You don't need the full setup, but get the coilover kit, single adjustable KONI shocks and some rear shock mounts.

Bilstein HD's are no bueno for GC kit if you plan on going low.
I think you can get them re-valved by Bilstein though

[Killacortes]

whats wrong with hd's for going low?

[LivingLegend06]

Hds are meant for stock height springs, they will bottom excessively when you lower your car. Bilstein sports are meant for lowered cars but some people running coilovers are still having issues with them bottoming out.

I have Bilsteins Sports and I am wondering if that is what is happening to me.

I have 2" of clearance for my skidplate and it has impacted about 6 times already.

So I would need a different shock or would stiffer spring be the solution?

I run Bilstein Sports and 350/475 Eibach ERS Springs with the GC conversion kit and the car rides awesome.

I was shocked (no pun intended) with how much better it rode on the GC conversion kit with stiffer springs and lower, than it did with the same shocks and Eibach Pro-Kit springs.

I also don't bottom out.

The lower you go the stiffer your rates need to be, and shocks to match. Depending on how low you go you may need the shocks and/or struts modified .

Both and/or depending how low you want to go.

Well all of the bottoming out happened the first day after I adjusted the ride height. Dropped the front 1" and the rear 1/2", for reference I am almost at the bottom of the Ground Control adjustment sleeve on the fronts.

I have driven more carefully to determine what is going on but I haven't bottomed out since, so would the suspension possibly have settled down now that I have driven on it a bit?

I have 440lb springs up front.

Bottoming out the shock and slamming your skidplate into the ground are two different things. With 2" of clearance, nothign is going to stop you from grounding the skidplate, but stiffer springs would help.

those are the springs that come with the bilstein GC coilover conversion kit correct?

^ they come with whatever rate you choose, call GC .

what rates would you recommend? i want to drop the front 1.5 and .75 in the back

[Jean]

Contact GC, tell me what you are trying to accomplish and they will help you pick the rates. It depends on many factors, you goals with the car, the shocks you choose etc.
