ive been reading through this thread. very enjoyable hahaha. anywhoo. if you look at my RRR WCE.
ive only applied the SP brake lever, SP rear shock stay and shock tower. the SP front middle shaft mount. SP chassis, kfactory brake disc/pads and kawahara rear bladed sway bar.
middle shaft mount = not needed
sp chassis = not really needed that much
kawa blade = isnt really needed either (can tune with std kyosho sway bars)
i only really recommend the SP shock stay and brake lever to anyone who asks me about it. the shock stay for more adjustability on the car and not having to worry about the shock tower. and the brake lever because the plastic one just doesnt do a justice on this car. although i <3 the kfactory brakes and pads only because i thought the brakes on the RRR were a little lacking.
dom is right about your obsession. only buy hopups you NEED. not want. youre just weighing down the car. and youll never really feel the full potential. rainier get out here and race! would love to have you pit with us and will.
