True Coil-overs vs. custom setup

[Ekliptix]

custom probably being koni reds and GC's for example.

The real coil-over setup seems to be about %60 more expensive, but how much more performance can be gained?

I think what you would gain in a single unit coilover system (ie: Bilstein..etc..) is the benefit of having the springs and the shock built to a spec where they operate to the fullest potential for a particular vehicle application.
When you put a ground control unit onto a set of Konis you do get a much better suspension system versus the stock setup. But when you look into the nitty gritty specs (ie: dampening rate/ spring rate combo) it may not be optimum for your particular car.

Complete coilover systems usually do carry a much thicker shock body, and shock "piston"...??? than your typical konis. There's prolly some benefit to this but i got no idea what...so someone here can help me out too.

This debate could go on all night, and probably will

If done correctly and with equal quality components, the "custom" i.e GC/Koni will perform every bit as well, or even better than an off the shelf set-up. In the BMW world it is generally accepted that the GC/Koni set-up is better performance wise than the off the shelf H&R and Bilstein coil-overs. Of course a brand xxxxx el-cheapo coil-over kit with Gas-O-Matic struts/shocks will never come close to a full Tanabe set-up!

ok, but if someone does get a GC/Kino setup, they should research the spring rates and correct struts/shock settings to get the most right?

Oh, most certainly, at least in principle. Why you ask...because the guys at Ground Control know soooooooo much more than any of us, or your "buddies" on the chat boards, about suspension. That means that when I call them (yes I am on a nice friendly first name basis with them ) and tell them what car we are working on and what the customers needs/expects, they will know what we need. They spend thier days and make a living making your car handle well, they don't want to screw it up.
