Thanks jneg for your reply. I was planning on using the regular RC8 chassis instead so it would be more of a Ofna DM1 length. I wanted to use the Protoform PF8 body so I think the buggy chassis should be the correct length? Would you happen to know?
I was also going to stick with the center diff for now and see what kind of results I got. Which towers are you using on yours? SC8, RC8? or RC8B? Also, do you know what brand springs would fit the Associated 16mm big bores, and if so, which ones?
I did have some ideas that might be helpful to you if you haven't already made a plan for your front and rear bumper (if needed). For the front, I found a link in a forum where someone else was using the Losi e8ight bumper on the front. It just needs some dremelling on the piece that goes into the front bumper slot. here is the link:
And if you need a rear bumper, I thought about purchasing this one:
I have the SC8 shock towers, but am trying to figure out if I should use the front one for the rear, and then try to purchase some body mounts to attach to the rear shock tower. I don't know if I will be able to mount the PF8 body this way, since I don't have the body, nor the body mounts.
Oh, also Associated is coming out with new arms for the RC8B. The shocks sit lower in the arms, which slightly lowers the center of gravity. Although I don't know if they would work with regular towers, because the shock ends might rub against the inside of the arm if they are at too much of an angle. Associated also released new towers to go with the arms. Could be worth looking into as it would lower the shock some and get rid of the risers.
