Also the steering arms, C hubs and rear carriers are also interchangable. So if you want grafite they already have them out.....Heck I just put in my Rayspeed Ti Rear CVD's in yesterday. Perfect fit. I will be gettign these items as soon as they are available.
BD-516L (front low friction belt)
BD-189L (rear low friction belt)
BD-TSS (Titainium Screw kit)
BD-BBC (Ceramic Bearing Kit)
Hope this helps having the part numbers ready for all of those who want them.
