Hmmm, Sounds like you should have bought the ground control kit.

This is what I have. Matt, what GC kit did u get used with billies? I though GC just used Konis.

GC sells complete coilovers with custom Konis, and a coilover "kit" that's basically threaded adjuster collars, springs and perches that you modify your stock strut casings for. So, you can run any struts with the GC kit.

Agreed, but there is more then a $250 difference between $850 and $1500. Then add another $190 if you want them to shorten the strut for you.

Glad you stepped up to some coils.

Why does EVERYONE get springs/shocks only to realize that it looks just as bad on their car as it does online, even though they hope it will look better on their car. It just baffles my mind, seriously, so many people do this.

I saw multiple pics online that I liked how IE3 and Bilstein looked. In the real world and on car my results were not the same. Maybe they didn't mention they had camber plates or didn't mention they cut a dead coil. I don't know.

Live and learn.

My total cost is still under the GC kit. To be honest with the revalve of the bilsteins after talking with Bilstein directly will work just as well.

are the bilsteins adjustable though? also, i would corner weight the car now you have coilovers if you want good handling on the track. if just for looks, then don't worry about it.

They don't need to be adjustable. If you know your spring spring rate, know the rate when compressed, know the spring rate at the wheel you can setup the shock for that setup. That is what Bilstein does via their rebuild/revalve service.

I will of course have my guy corner weight/balance the car. I need the parts installed and my sway bars on. Then get it all done at once. I know all about that.

I was directing that at White since he said you should have just bought new. When it's not even close. $850 is good price for a used coilover setup.

Of course Bilstein is going to say there stuff will work as well, what did you think they would say. "Yeah, we can revalve them, but you know, short body Koni's are really a better to keep your travel and add adjustability."

that's a rough adjustment, that can still be tweaked depending on conditions and track with an adjustable setup. GC Koni's are also custom valved based on the rates you select but you can still adjust rebound. I typically set it up and don't touch it all weekend but it's nice to know you can.

What rates and spring sizes will you be running?

Are they really? I was under the impression that GC Konis were simply a different rate than standard konis, but not specific to the spring rate selected.

I understand this and while it would be nice to have the Bilstein is really a better shock(in my experience and opinion). Yes it lacks the adjustment but honestly I don't have the knowledge to tweak at the track. I want it setup and done and I will adjust as the driver. I had a great experience with my shortened and revalved Bilstein sports on the M3 and I will do the same again. I loved the way that car handled.

In the end if it sucks horribly I will switch it up. Honestly I enjoy the build, tuning and modding than the actual finished product.

I think I will end up with 550/750(maybe 800ish)

I believe GC can spec the Koni. I am not 100% sure. Regardless I am going with what I want. The road to get there I may have taken the wrong turn but I will get there :)

nope. they are re-valved based on rate you select.

well that's good to know. And now I get why people run GC's. I am still surprised I don't see anyone with KWs or TCKlines or anything.

Nice progress Dinan. Will definitely be a sick car.

[dinanm3atl]

I don't really know. They both make good stuff really.
