I was looking to do a C6 FI build. I did not want to molest my current cars and was looking to do a FI build.

I get several good pieces of advice:
- seek out a later C6 to get the benefits of the better engine and beefier drivetrain
- avoid the auto cars, as likely will have more issues with the level of HP I was looking to achieve
- if buying a modded car, do not give much for the existing mods

I tried to adhere to this advice. Purchased a later model black coupe.

I am now in the stages of planning the body mods. I want larger rear tires under the back end. I have already begun the investigation of the GS/Z06 rear on the coupe. Currently running 19x10" rear wheels and want to be able to use the black GS wheels; 19 x 12" and a 345/30ZR19 tire. Currently considering the Nitto Invos. Fronts are currently 18 x 8.5".

Questions:
1) Thoughts on leaving the narrow front end on the coupe and retaining the narrower 8.5" wheel with a 245 width Nitto Invo?
2) Any concerns with tracking issues associated with the 245 width on the front and the 345 width on the rear? I have always been fine with the skinnier fronts vs rear.
3) Anyone have the weight data on the black Factory Reproduction GS 18X8.5 5X4.75 +56mm and the black Factory Reproduction GS 19X12 5X4.75 +59mm vs the OEM black GS wheels? Is there a significant weight penalty with these aftermarket wheels?
4) Will I still be able to use my LTPW sensors with the aftermarket wheels?
5) How do the Nitto Invos hold up to higher powered cars? Is there a better option that is not over the top on costs?

Thank you in advance for any help you can provide.

 

I went five tire sizes larger than stock (Z06 widebooty) front and rear. I actually saved weight over the stock setup but I also went with forged CCW C10s. 18X10.5 fronts and 18X13 rears. Toyo R888 295/30/18 fronts and 335/30/18 rears.

I just finished my rear conversion. 19x12 Spyder repro's with 345/30's in the rear with the stock 245's in the front. No problems yet. I think it looks good and tracks fine. My only complaint is that the width of the flat arch on the fenders don't match front to rear

Wheels and tires = $1000 (smoking deal from DadzC6)
Conversion parts from dealer = $1500
Paint = $400
Total = $2900

Just picked my car up from the body shop. Had rear wide body installed . I'm running LG world challenge wheels 275/35/18 on a 18x10 wheel upfront and 345/30/19 on a 19x12 wheel in back wrapped in nitto invos. Love it so far. No problems at all.
