Im at my limit on front tire size now running 27.5 on my dart.I just put a Gerst tubular front suspension on it and i have the rebound set as soft as i can on the viking shocks to allow for most rise.Im looking to slow things down aprox. .030.I run 28.0 x 10.5 in the back usually at 10 3/4 pressure.I footbrake the car and it reacts very quick.I may try backing off the timing kill it a little off launch.If i tighten the front shocks im assuming that would make it react quicker with less movement up?
