Questions on Lowering with the F45 system
Just need some input on lowering a car with the F45 system.
1. By doing the "standard" lowering trick just doing the stock bolts does this screw up the F45 ride at all?
2. If #1 is "no" then can I lower it even further by cutting bushings without screwing up the F45?
I have put Z06 wheels/Kumho Ecsta MX tires on it so the installed height is 1" lower than stock to begin with. I would like to decrease the wheel well gap over the tires.
Thanks for your info and opinions ahead of time .

Re: Questions on Lowering (a6fan)
Installed height of the wheel and tire combo IS 1" less than on a stock C5 wheel and tire combo. I am using Stock Z06 wheels and Kumho Ecsta MXs in the stock Z06 sizes. I will modify to include F45 in the header.
Thanks

Re: Questions on Lowering with the F45 system (a6fan)
Rick, I have the F45 suspension on my 99. Lowered the car by just turning the stock bolts and wasn't happy with the stance :nonod: Jacked the car back up a little later and removed the front bolts all togethrer. I even shaved 1/3 off the rear bushings too! :thumbs: Car still rides great and handles likes its on rails. Still has a little gap in the fender wells but can't really go any lower unless I go with coilovers. Good luck and drop that bad boy, you'll love it :reddevil

Re: Questions on Lowering (CPT Z06)
What? Why would Z06 wheels be lower than "stock" I know they are not.
The stock Z06 tires are about 5/8 - 3/4" shorter in height than the stock C5 tires.
245/45/17 - 25.7"
265/40/17 - 25.1"
275/40/18 - 26.8"
295/35/18 - 26.1"

Re: Questions on Lowering (Y2Kvert4me)
Yes, the stock Z06 wheel/tire sizes have a lower overall diameter than standard C5 wheels/tires but of course the car isn't actually lowered by that much, only half of it (car rides on only one side of the tires at a time ;))...but it can give the look/appearance (and reality) of larger wheel well gaps.

Re: Questions on Lowering with the F45 system (a6fan)
Basically, I included installed height numbers because there is a difference between the Z06 and the EMT tires. I am concerned with making the F45 "read" the car as too low (hitting a bump?) and stiffing up the shock so as to make the ride too harsh all the time. Maybe I'm not giving the computer enough credit but I read something on another web page about how this 'might' be a concern so I wanted some answers from ownrs who actually did the lowering on an F45 car. I appreciate your time in answering.

Re: Questions on Lowering with the F45 system (a6fan)
2000 Cpe with F45. 265/35/18 frt & 295/35/18 rr. Lowered front 1-3/4 by cutting 2/3 off bushings & rear by 1-3/4 with longer bolts. Ride is firmer but acceptable to me. Had it 1/4 lower but was scraping on everthing. Just raising 1/4 made a big difference. Also felt like the shocks were bottoming at lower height, now OK.

you literally just removed the front bolts? that doesn't effect driving ability at all?[/QUOTE]
Oh yeah!! Yanked those bad boys out of there! Had an alignment after settling and haven't had any troubles. :D
