Did you use the RC8B standoffs for the shocks? The bigbores will rub
if you use the original standoffs, they also hit the wing mount in the
rear. Make sure they are not rubbing on anything.
The factory Bronze front springs are to stiff even with the forward
battery location. You want the silvers. #89293 front and #89348
Rear. This spring set should help alot but you should also move the
Battery forward so you will be working with the same weigth distribution
as the RC8B. The forward battery box tray is #89471. These are pretty
cheap parts figure 6 bucks apeice for the spring sets and maybe 8-9 for
the Radio tray. The standoffs are not cheap though so if you have a limited
budget just get the front ones first.
Dont worry to much about the steering mod yet.
Get the proper springs on the car, move the RX battery forward, and make
sure you dont have any binding issues in the suspension.
I've done the battery box mod. I'm using the factory standoffs, and it doesn't seem to be making the shocks hit anywhere. But they do come very, very close in the rear when the shocks are fully extended. I haven't seen any marks yet that would make me think they were hitting.
I'm going to order the spring kit the next time I place an order for anything, and I'll also look at the other standoffs. I like to wait until I have at least 100$ worth of stuff so that I can use a coupon. I know it's only 5 bucks I save, but it's also alot more exciting when you get a bunch of stuff in the mail at once, plus the savings add up on the shipping a good bit.
