Suspension first guys. JMHO !! I have been around the LSx game since 2000 when I purchased my FRC with .2 miles and drove it off the truck myself . I didn't mod for a few years due to having an extended warranty and all. My first mod(s) were the B&B bullets for a few hp and a lot of extra sound. I later added a very smart mod, VaraRam CAI. No tuning needed for either and I was happy for awhile. Rather then go into the extensive list of mods my car went under in 05, 06, 07, 08, and 09 I'll just say this: I think the first mod(s) for a corvette, especially a c5 should be coilover shocks, sways, poly bushings, and a tune. These cars make a good amount of hp straight from the factory, all they need in my opinion is an over the top suspension to make them handle better. My question is, why is everyone (myself included) in such a hurry to add hp vs suspension to get quicker? Seems like suspension and brakes are the last things to be done. Suspension as we all know can make or break you at the track. 9 times out of 10 the guy who wins the 60 foot usually wins the race. Also a lot of guys are auto crossing there c5 corvettes. What better combination then a set of ADJUSTABLE Pfadt coilovers, sways, and poly bushings ? Perfect for the track (road course / quarter mile) and the street. Once you have the suspension dialed in and the car is as fast as it can be, THEN add horsepower, adjust your suspension and watch how much quicker you get as you continue adding hp and adjusting your suspension !!
Pfadt coilovers, sways, and bushings available at Vengeance Racing 678-523-7105 tell Ron that Doug sent ya.

I agree. My car has Pfadt coilovers and I LOVE them! All I have for power right now is a Corsa catback and Vararam. Coilovers are by far the best mod i've done! The adjustability is amazing to boot!

...Everyone does power mods cause they don't want to get beat. I agree though, regardless of the choice of suspension, you should without a doubt look into a kit. I agree, after all the extensive mods, coilovers(I run a doug rippie setup) are by far, one of the best mods a Corvette can undergo. Hands down, top 5, maybe top two mods. Really changes the way the car feels, giving you better feedback and body transition. My car has zero body roll. Damn near zero brake dive. Drive a car with coilovers, you'll never want to go back to leaf springs.

Thanks guys ! I'm glad you guys can see my logic. I posted this thread on CF and got ripped on. Oh well, opinions are like a$$holes, everyone has one.
Hey Superman, let us all know when you start modding and if any adjustments are required to be made to the suspension after increasing power. I'm sure you have her dialed in for the power your car is making already. BTW glad that ticket issue worked out for ya !!!

i agree, that is what i did with my mustang before i sold it, bilstein shocks and struts and H&R race springs among other suspension bits...
so if y'all say suspension first on the vette, that's what i will do first, just gotta figure out which coil overs to get

the pfadts i rode on were just exactly what i'd ask for from a suspension. rode like stock, completely flat in the turns.
in the past ive had a few toys.. i STILL do all the go first, the turning and stopping last. BUT, i will say that everytime i am seriously impressed with how much the suspension changed the whole car. in one extreme case, i went from cutting 1.95 60's to 1.65 in the exact same car exact same tires exact same everything except suspension. (BFG DRs were the hot ticket at the time) so anyhow, i see your side and agree or disagree based on the car owners goals.
for me the Z provides more grip than im used to as it is, but not so much in the acceleration department.. so thats where im headed first

hmm i never thought of it that way...good point allgn C5. I have an 01 Z so for the mods i currently have i think im ok due to having a better suspension out of the box. However there is ALWAYS room for improvment. I may actually look into supension now instead of doing a cam first. Thanks!

Pfadt coils & sways were the first changes I made to my F45 Vert. The better control combined with reduced dive & squat actually made the car feel slower.
I've corrected the power part now.

Call for a quote, everyone is different. I did look around before I made the purchase and Vengeance had the best pkg price. They also price match.
Thanks for seeing the idea for what it is, vs saying its wrong to do suspension first.
I know what you mean. When a car is out of control it feels much faster then a car that is in control.

The weak link in the Corvette Z06 is BRAKES !!!For track use....road courses, you will need to change:
1. Brake fluid and add stainless steel brake lines
2. Brake pads
3. Rotors
4. Cooling ducks
Next step is a modified "track/street alignment" and corner balancing.
You will need to add a harness bar and five or six point belts.
Also... now cooling will become an issue. A combo heavy duty radiator with oil cooler (Ron Davis) works fine.
Then, after many weekends (maybe a year or so doing "D E Events") at the track you will need new wheels and Dot "R" tires.
That's the "learning curve" for moving up in run groups.
Only then... should you consider major suspension modifications.
Lots of info at both www.corvetteform.com in the Autocross and racing section. Also check out www.sccaforums.com in the T1-T2-T3 section.
Power is not the issue... even with the C5 Z06, driver experience and track set-up provides the best results. These cars hold up well on the track keeping engines "stock". Modifications will reduce the engine's reliability substantially, as the horsepower goes up... reliability goes down.
I've instructed for many years and most of us instructors follow those steps.
Having owned and tracked an 01 and 04 Z06, as well as my current 07 Z06, this has proven to be the "best route".
