You may want to rethink those RPM arms, I can't recall hearing anything good about them, especially if you want to run a cvd. I have abused the hell out of my stock arms and the only time I have broken one was on my nitro 3.3 when I hit a lightpole at nearlly 40MPH, took out both arms, drive axle, and steering hub all at once. That was a solid hit where the truck went from 35-40 to 0 in a split second. I have lawn darted from 20 feet, hit sewer vents, rocks, and cartwheels since and never had a problem with any of those parts.
I have already been through two front arms, so im hoping that the rps will be a little bit more resilient. as far as cvd's go i wasn't planning on running them as i have seen that most people keep with the stockers even in high power situations. well see, if i keep breaking arms then i might just have to drop some doe on the flextek titanium ones....havn't heard anyone say bad things about em.
