RCUANUT,
thanks for the kind words. My next step is to put the ligh vented flywheel on and keep the Mugen 1.0 springs with Mugen carbon shoes. I will change out the front shock to 40 wt oil and the rear shocks to .35 wt.
I am glad the Mayhem is working for you. I swear I am having so much more fun with the buggy. I purchased Soft Panther Komodo Dragon tires to run and this should even more help.
Have fun.
Rockman
