Small bast won't fit the new car...the shape messes with the shocks! Tried the JC and works really good!

I have used the JC wings for years and they hold up well. I am usually on my lid at least four or five times during a race night.

I've been using them on and off.
They're a bit flexible, so if you want a stiffer wheel look elsewhere.. Haven't had any real issues with them though, they're fairly durable.

Thanks Kevin. I'll pick up another set of KYO wheels. Do you know if WC has any in stock?

last Sunday I was there, they didn't have fronts in white. Not sure if rears were in.
I believe Flo yellow is in stock, But wouldn't hurt to give the shop a call.

I liked them on my B4.1,
but how do they fit on the rb6? I know JC Monos didn't fit right(I didn't like how they sat), and these AVID wheels rub a bit up front..

The fit is fine, the offset looks the same. The hexes are a bit tighter though and sometimes i have to wiggle it around to get it seated - unlike the K's which just drop in.

i run the proline wheels and like them alot the only thing is and i think this is y tebo runs the older front axle and hex is that with the hex being so narrow the wheel rubs the spindle. i just dremel down the back of the wheel and they work and look great. I also run the proline wing and like it much better then stock
