I'm looking for a new set of wheels/tires and need some help on some size feedback and also wheel options for my ZR1 widebody 05:

Styling
1) I really like the 360 Concave 5's. I'd like something like that or the split 5's, but definitely concave.

2) Gunmetal, Black, and Machined aluminum are all options.

3) Prefer a one piece lightweight rim

Sizing
I'm wanting to run an R888 on them. The car is a twin turbo and will make around 1k rwhp. I'll turn it down for the street and also have boost by gear, but I'd like to get as much traction as possible. It will also see some road course duty on this setup.

So I'm thinking about a 275/30/18 and 345/30/19 setup. A couple questions:

1) Anyone had active handling or ABS issues with those sizes?
2) Are the 345's too much? Perhaps a 325 might be better? Not sure what I'm worried about here really.
3) What rim widths? 10 x 12? Not sure if the R888s run a little narrow or not.

Finally, any recommendations? I saw a 1-piece HRE concave split 5 spoke that I liked. I think the picture had it on a white GTR with a big wing.

I'm not sure if the 360s or the HRE's come in a the rim size I would need.

Vendors are welcome here obviously

Hello take a look at Forgeline they have one piece concaves available in 18/19, we dont have 360s or HREs available in those sizes in the concave profiles you are looking for

I took a look at the ones I liked and they didn't seem to be available in 18s for the front.

in case you want to go wide 18's at back , I have 2 new 345-30-18 Michelin Cups for sale cheap. Many C6 do this set up for more 'rubber' side wall , so they push the crap out of their LS2,7, Let me know , in case

Have set perfect Forged 360's not using would sell. 20' though. Rear wheels are 1-1.5 larger diameter very concave. Will fit c5 ZR1. Shiny black. With that power best option nothing will hold that well that is streetable but probably a drag radial best compromise. Probably your rear is 1.5 inches extended so hub space for better look.
For full on drag radial smaller whe but doesn't drive, handle, look good. I bet 19' w NT50R optimal. ZR1. Have a good Nitto's on them now but not drag radials. Mono block construction so lightweight and strong. Looks like you're wanting to go smaller but if interested don't hesitate to text/call info/pics. Sell for 3500 OBO. Rear 2.4 lb lighter than cup wheels (cups lighter regular). Forget front difference. They are a lot lighter than the tires you will put on the car.
Thank you,

pS I have about the same power. New Michelin cup sports had no traction. After 2 two full long burnouts held fairly well.

is it a widebody car in the front as well?

if you are going with a 345 rear you need to run at least a 295 front. If not prepare for massive understeer

Thanks Luke. Yes my car is 295 stuck in the front 20 inch wheels and three 335 20 inch wheels in the rear.

I had replied to answer guy with a question about this but I'm glad for the information. Yes mine is widebody up front as well. I have generally bought my tires from you guys so you're likely hear from me soon. Thank you, George
