Car looks great btw!
Ive read mixed reviews about a 40 sidewall tire. I’m lowered in stock bolts in that picture, I’ve read where a 40 can rub the brake ducts and other frame components.

Thank you for the compliment as well!

17 front 18 rear, which to me is weird because I normally have the larger diameter wheel up front. I too like a good meaty set of tires on my wheels.

I wish CCW's were in the budget. Great looking wheels!

275/40/17 up front and 305/35/18 in the back. The offsets on the wheels is a little weird, the fronts seem to stick out a little too far and not far enough in the back. The back I am running a 5/16th spacer with longer studs.

18/19 also causes no problems with active handling

If the wheel offset is correct, a 295/40/18 should fit fine.

it is because little kids who played with hot wheels grew up, driving the market to larger wheel sizes everyplace where looks move product, you don't see F1 cars rollin 20's. Additionally , when shopping for aftermarket wheels , most modern designs don't even bother with anything below a 19" with some rare exceptions, so that probably accounts for the conscious reasons to buy a heavier wheel tire combo. the muscular look of a big rear wheel arch looks powerful.

Realistically If you want to stay around two thousand bucks , about the floor when buying new wheels, and considering the value of the car, there is not much out there n 17/18 besides a few old cast hot rod designs( torque thrust II is popular) , Chinese TSW wheels, or offshore reproductions of other, more modern corvette wheels, cast in the C5 size . The TSW are forged in Z car sizes only, so a little wider than a base set up. Most of the TSW stuff has a larger diameter, the c5 size is growing old when you are designing for modern markets. I would guess most C5's , if they haven't gotten new rims by now, never will, judging from the interest shown by wheel companies.

Of course, some will say the extra room in the wheel well is only there so snow chains can be fitted, which is an unneeded feature for most, .except if you are a lawyer at Gm. I figure I can always buy a stock size tire from a major brand , so I stay with the size the ride was tuned for, or close to it, not wanting a run flat design rubber.

I am sort of in the same place. I think the oe Z wheels look great and I think the 17/18 sizes match the car very well. Unfortunately the previous owner of my car had the oe wheels chromed and he later c6 zr1 replicas on the car.

I wish i could find a set of clean oe Z wheels in the argent gray at a reasonable price.

The limited tire selection in oe sizes does have me considering an 18/19 setup however.

18/19 polished aluminum crays

They came painted silver. I had them stripped and polished.

The OEM wheels are great, but they look a little old-fashioned because of their size. I have all season tires on them and use them in the winter. I have summer tires on the Crays.

I saw these rims and fell in love with them. This was back in 2003. They were only available in 18" and 19" They still look new today.

My black coupe has stock C5 Z06 rims on and my red coupe has 19" and 19" CCW rims.

I ordered two brand new OEM z06 rear wheels for $780. Now running the 18x10.5 OEM wheels on all four corners with 285/35r18 ps4s, which are an amazing performance street tire though a bit pricey. I also now have the ability to rotate front to rear, which should help lengthen the useful life of the tires. Very happy with this setup.

This actually sounds like a good option, although I'm wondering how the car drives with 285's up front? Any issues with that? Any issues with rubbing up front?

Any pictures of the car?

Here are a few pics. Sorry I don't have anything better. I was nervous at first as to how it would look that wide in front and you really have to look hard to notice that it isn't stock. Looks more or less the same. There is a tad bit more poke in the front, but that doesn't bother me and most people will never notice.

I personally like the "square" setup with the same size wheel/tire front and rear. It gives it a more neutral handling feel, which I prefer. A staggered setup will tend to understeer a bit, while these are a bit more playful. No rubbing that I have experienced. Only real downside is that the car will follow grooves in the pavement a bit more with that wide of a front tire. That didn't really change the driving experience for me personally as even in stock form, driving a c5 z06 is a very involved experience and the car demands your attention while driving. All of that said, even with the square wheel setup you can go with a staggered tire setup going either wider in the rear or more narrow in the front (or both of those options). To me that kind of negates one benefit of running a square setup in that you lose the ability to rotate tires.

All excellent points and very much agree that the car demands your attention. Appreciate the feedback. Nice looking car as well. I was looking for a silver car but couldn't find one when I was looking to buy.
