Is there any way to use OEM center caps? I don’t remember seeing anyone use them.
I don't think so. I tried and its a different size than OEM. Maybe somebody makes an aftermarket... IDK
Also, can I get away with using the stock tire on these wheels til they need to be replaced (probably with 235/40s)?
225/40 is going to looked stretched on a 8.5 wheel. If you like that look, it will fit. 235 or 245 is a better width for a 8.5 wheel.
Finally, where can I find the best deal? Have any of you had any experience with discountedwheelwarehouse.com?
I bought my VMR 710's from there with tires mounted and balance. Great price but no communication. So make sure you have your order right when you place it. This company doesn't answer their phone or respond to emails.
Thanks ahead of time for any help and suggestions. I just got the car and am loving it.
