19" square wheel/tire setup
Hi everyone, I'm new to the forum and to c5 z06 ownership (I bought my bone stock, black on black, 2003 c5z w 39k miles on it back in November 2015) and I'm already looking to upgrade my stock wheels. I've been researching online for a while and it seems that the lightest and cheapest option for a square setup is to buy two additional stock rear wheels and bolt them up front. However, I'm not a huge fan of the looks of the stock wheels and I would prefer a 19" diameter for aesthetics but i'm having a hard time finding any wheels in the required offset. The wheels I found recently that I like are relatively lightweight and inexpensive (spun forged 24lbs each) and I think they would look great on a c5z but the only sizes available that would even remotely fit are 19x10.5 et45 or 19x9.5 et58. I would like to run a 295/30/19 tire on all four corners so the 9.5" wide wheel is probably out of the question. Is there any way I can squeeze a 19x10.5 45mm wheel onto all 4 corners of my c5z without it looking like hell?

19x9.5" up front with a 275/30/19, T1R
19x11" rear with a 305/35/19 R888
These were built specifically for C5 fitment. The fronts do poke just a tad but it looks fine.
Note...
Any 3 piece wheel is gonna be heavy. I was quite surprised to see how much heavier these IForged wheels were then stock. Fronts were 7lbs heavier each and the rears were like 9lbs heavier.. Stick with a 1 piece forged wheel for weight savings.

Nice ride, what offsets are your wheels? I like the look of 19s on a lowered c5z. However, I want to run a truly square setup with identical size wheels and tires on all 4 corners so I can rotate my tires and get optimal handling. I need to know if I can install a 19x10.5 et45 on all 4 corners (or a 19x9.5 et58) without them either sticking out too far (not flush w fenders) or being too skinny in the back and/or too narrow to run an optimal tire size like 295/30/19 or perhaps even wider tires for the track. I've used an offset calculator but I don't want to buy wheels unless I know for sure that they'll fit right.

You can probably get the 19x10.5 fit on the front but definitely not a 295... That tire would be HUGE on the front, no doubt it would rub on everything and probably drive like crap. Even the C7Z only runs a 285 up front and many complain about how the car tracks on them on public roads.
I don't see a square tire setup working and looking right...If that was the case, they would have done it from the factory.
You probably "could" do a 285 all the way around but...I think it would drive crappy and look worse.
Even on my wife's G8, I run stagger fitment 19"s..(245s front/275s rear).
Do what is going to drive and look the best...Its a sports car, not a family sedan.
Stick with what works, use proven sizes and offsets. No way are you gonna be able to run the same offsets all the way around.
