That is simple goto www.hpd-inc.com there is the best parts in my mind an alot of others too.

 

All HPD stuff for motor and clutches.

Works for suspension.

 

Stick with HPD. I tried one of those "kits". Although the performance was decent, the quality, and fit/finish was terrible. I then switched to HPD. Everything was just how I liked it, great quality, fit/finish, and the performance gains were incredible.
