Hello, I bought some new Pro-Line 2.8" Street Fighters that I plan to mount on 2.8" Desperado rims for the rear of my Rustler XL-5. I think this rusty will hit between 60 and 60mph with my 3s Lipo setup. However, I am concerned about ballooning and control with the Street Fighters. I have already taped them with Gorilla Tape, but am looking at either buying new foam inserts or somehow strengthening the stock inserts I have to make them more rigid, increase control, and decrease ballooning. Any suggestions would be much appreciated!
