ordered up the qa1s... now going to order the GC kit and i want to know what everyone is running... do you like it? wish u went stiffer of softer? and is it a DD car or only track car... or what?

i think i want to go with 600f/650r to make it a bit stiffer because i drive very hard and beat the snot out of the v.. lol

let me know... thank you.

Where did U order the QA1 from?

Started with FE4s here, and GC people talked me into 550R/500F springs. Had 'em about a month or two, and someone here wanted to trade for their 650R/600F, so I made the swap. After over a year, Luke sold me a set FG2s. The car is NOT too stiff by any stretch, IMHO ... on the contrary, this is the way it should've come from the factory. :thumbsup:

Just my $0.02.

I have FG2 and 650R/600F GC, my car is DD with a couple track days.

It rides nice and If I would do it again I would get even stiffer springs, as the car still rolls to much in hard cornering.

Also I saw a thread where a guy with QA1s and with 650/600 springs was having trouble without the ride correction stock setup and people in the rear seat. Something to think about...

hmmm i do want her stiff and qa1s nice cause you can adjust them and rebuildable

I have FG2s with GC 550/600. Mine is a DD and I'm in NYC. Not very harsh at all. I would probably be happy with a 600/650 setup.

Might want to throw in your sway choice as aftermarket bars will change the effect rate at the tire which your is primary concern.

I don't know if I'm sold on the 650/700 springs. On highways and smoother roads, it's not bad. But I'm not horribly fond of them on rough roads. Handling-wise, though, they're great. Totally subjective, but I hit 1.07g relatively easily, seemingly moreso than normal. Flatter cornering for sure...

Don't forget to get the Z06 endlinks (or similar).

Luke has 'em ... decent price, too.

05-20-09, 08:42 AM
oh yea those too... add them to the list.

05-20-09, 10:28 AM
... the Z06 endlinks ...Part No. is 15288535.

Don't forget to get the Z06 endlinks (or similar).

Why is this? Because of a different ride height?

Yup, they are shorter.

My car is D.D. and used to be a track car. 650f/700r G.C. with FG2. I think the combo is just right depending on your track experience. Forgot the Eibach Sways. Hope this helps.
