Hey guys I was planning on buying a c6 in the near future. Older brother and I are already thinking on bumping up the power. I decided on buying an STS turbo kit that will get it up to 487rwhp and 501rwtq. Since we wanted it to be more than a straight line performer we were going to get it wider wheels and Z06 brakes. To get the handling up to par we were interested in purchacing Pfadt coil overs and z06 sway bars. My question is would the coil overs help with the rear wheel traction and what would they do for the handling and everyday drivability in general? Thanks in advance.

yes the coilovers almost emliminate wheel hop, slap on a non runflat tire and you will be good to go. also howcome z06 sways and not pfadt sways?

I have recently installed pfadt coilovers in my c6 z51. The general soft and floaty feeling of standar suspension is over. The stock z51 has a lot of bump steer, now with coilovers it is also over. When acelerating hard, the front does not rise up, as before with the stock Z51, when braking the front does not dive. Now I'm able to perform corners from 1g to 1.10g very easily and flat. The steering feeling has also changed, now the car is very reponsive.

For me is like having a total different car. I'm so confident with the feedback of the car, that it seems to me I'm going slower than before. I have a corner full o bumps in a local highway. In the stock configuration it was scary at high speed (you where jumping all the time and loosing your trayectory). Now I'm able to take this corner 30 mph more, and the car follow sthe curve perfectly.

This kit is so configurable, that you will get the best setup for your personal taste.

Choose also pfatty sways, they are adjustable and stiffer than z06s :thumbsup:

Well said and i agree 100%.

Pfadt sway bars are much stiffer than the zo6 setup and besides they are designed to be paired up with the pfadt coil overs....which by the way ROCK!! I notice my new coil over suspension most when i'm changing lanes under acceleration or when i'm taking a tight corner.... the car stays level and feels glued to the road....as for better traction (with increased HP) to the ground - You Betcha....you get this by simply eliminating the wheel hop and getting a more even/steady/continuous application of power thru the tires making more intimate contact with the road..... the OEM C6 leaf spring suspension (IMHO) sucks. One extra added benefit is adjustable ride height!!

The z06 sways are cheaper ($239.95 to $1,075.00) but if the pfatty sways are good enough to justify the price difference then we'll consider those.

P.S. this is probably a dumb question but I take it I can remove the leaf springs when I install the coilovers?

On another note we were wondering how wide the rear tires would need to be to handle that kind of power are 325's good enough or would 345's be necessary. If we got the 345's then we would probably have to get 12 to 13 inch rear wheels which would require z06 fenders.

exactly. I am running a DISC stage 2 ATI bblower with 10 psi which gives me north of 670 at the flywheel... to handle this increased HP I had new z06 rims widened to 12 3/4 " to take Michelin PS2 345 ZR 19x30 tires.... but this also required new zo6 rear 1/4 panels.

How much did it cost you to have the wheels widened?

Approx Cdn 300.00 per rim. Another 50 per rim to mount and balance the new tire.

i this safe? can the wheels still go 200 mph? i love my stock wheels but would very much like z06 sized rubber.

z06 rubber is only 325 x 19 x 30.... so you don't need to widen the z06 rims to achieve this - but if you are going to retro-fit these onto a c6 you will need spacers and wider rear 1/4 panels. IF your goal is more HP then you will also want to consider widening your z06 rims so they can take 345's - more rubber to the road means better traction. The rims are widened using a robotic arm/laser welder. They are just as strong as the originals. i am getting my car geared out to run 215-220 mph so i guess i'll let you know just how safe they truly are. As for a place near Minni that widens rims - no idea. try doing an internet search or asking your local chevy dealer? Up here in Canada the guys that custom paint rims also repair /widen the rims so perhaps that is a good place to start.

You don't need to widen the Z06 19x12 wheels to except 345's I've been running them 345's on 19x12 stock Z06 wheels for over a year, fit/ride/handling is excellent! they fill the wheel well much better than the 325's also:thumbsup:

You're right . However, when you widen the rims to 12 3/4" the side wall of the 345' dont bulge out over the rim as much. I found that widening made the tire profile against the rim look a little better.

Here's a couple of pics of my 2007 C6, with ZO6 quarter panels, CCW SP20 wheels, and Michelin Pilot Sport tires. Fronts are: 275X10 on 10" wide wheels, and the rears are: 345X13 on 13" wheels. Everything fits perfect with these numbers.

Looks badass...nice pics to go along with that combo:thumbsup:
