so wait, for fe4's, Daily driver and increased performance you guys are recommending??????????

let me know, i wouldn't mind same ride quality with 1.2" lower.

Based on WW's experimentation, sounds like you can order the kit with no springs, use your stockers and just lower the ride height. I think Dreamin' has the FE4 experience, he needs to kibitz here. Check with GC and make sure you can run the stockers on their adjustment collars.

What kind of tires are you running and do you have the Hotchkis anti-roll?

For the gurus... I'm running CCW SP600 19x10 in the rears, any issues with this kit and lowering?

Thanks!!!

Calicadi -

you CANNOT, repeat CANNOT, use the stock springs with these collars - different ID/OD and length.

I would never think about use the springs that are currently on, I do want to retain ride quality if it stiffens up 20 30% o well as long as the handling gets better.
I also plan to put on the swaybars at the same time the gc kit goes on.
I have stockers with 275's on the rear, what are the sprng rate suggestions guys?????

I wish I could be more helpful to those with questions but my install is a week a way. Only two (that I know of on this forum) had GC prototypes and/or conducted their own experiments. There just isn't a broad spectrum of experience and data yet. We are on the cutting edge here.

Read posts 200 and 205 in this thread.
Call Ground Control.
Google suspension setups and check other performance car boards.

I think the consensus now is running with FE4s will be better off in the under 500 range and FG2s can take more spring. Regards lowering, we need to get data on optimum lowering settings from those with stock and those with non-stock rim and tire combos. We need more data points but won't get them 'til more are installed.

Valid points, CC.

I can tell you that when I throw 400 lbs of human in the back seat, I do rub on the passenger rear over large bumps, UNTIL, I've driven a few blocks (Nivomats at work?). I have the car quite low, and also have 275's on widened rears with spacers. Stock tire sizes on stock rims this wouldn't be an issue.

Can't wait to hear more reviews on these. I know how well I thought my car was riding with slightly cut rear springs and grooved front shocks for lowering. The spring rates in the GC kit are much better up front, and seem to be in the rear as well. That with the added adjustability makes it a perfect solution, IMHO.

T/J on

"Who needs a MAP sensor on a supercharged LS6 anyway."

Only those with a 2 or 3 bar tune? Alky injection?

I don't know...I probably don't.

T/J off

Well, I put in my order for the track/auto-x setup. I assume this is the 500F/550R setup. I did note that is the spring rates I wanted in the notes on the order, but I was wondering if anyone knew for sure...

With a start of only 40 orders, I just went ahead and ordered so that I wouldn't miss out.

500/550 is 'street performance'. That is the spring rate I wanted, so I called GC yesterday to make sure.

Well, unfortunately, I was at a conference from Friday through Sunday and my home computer crapped the bed Thursday. So I scrambled at lunchtime on my laptop to order. If I wasn't rushing, I would've called myself. Hopefully, somone over there reads the comments box and won't send me the uber-stiff, innard rattling springs...

thebigjimsho · #**224** (**permalink**) 07-24-06, 07:05 PM

Well, I was happy to receive a call from Ground Control today. They wanted to make sure I got the springs I wanted. I almost decided to try the 600/650 because of positive reviews they've gotten from them. But since it will still be driven often on bumpy roads and such, I'm sticking with the 500/550 setup. I should be getting them this week.

Kyle15 · #**225** (**permalink**) 07-27-06, 11:36 PM

I think it is intereting that they are getting the initial view that stiffer is better as far as handling goes. Probably shows that we don't have enough bar/shock. In any balanced race car, you want more grip.....softer.....to an extent of course. I know open wheel cars like Indy Lights were running under 150lb springs at the end there and the Nextel Cup cars are under 500 pounds in the front pretty consistently now.
