In the May issue of MMFF there is an article about a HPP twin turbo cobra setup. 820rwh. This guy figured the IRS may be an issue so he utilized a pair of Level 5 halfshafts , a Billetflow diffrential brace and Maximum Motorsports aluminum bushings. This was to keep wheel hop in check.

I have serious wheel hop on my 04 cobra. Was told to change the bushings to mm bushings. Lowering mine really helped but stilll hops bad.

Installing the mm bushings will help alot.
