The wheels are actually wide-body versions of the HRE C21 Cup or GMG Cup Racing wheel. It looks similar to a C21, but not the same wheel. These have been worked even further to reduce weight. Look at the inner-part of the spoke. It has been machined more vs. standard C21. See standard C21 here:

Now see that wheel here:

Thanks!

 

Wow....This thing knocks me out. Well done and tasteful work! The green is the best color for these cars and it reflects in their resale value!

 

Fabryce,

The car looks awesome! Thanks for the support!

I know i'm digging out a pretty old thread but I would like to know the following:

How does the rear strut tower extension and brace for 6 anchor points attach to the world challenge roll bar?

 

There are two provision-mounting tabs located at the main hoop which attach it to the main portion of the bar.

 

But only on the newer versions of the world challenge roll bar?
Can't see any mounting tabs here.

 

If you have an older version of the bar we do offer a retrofit kit.

Email me directly.
