I run stock 17.5 and made a couple changes this saturday. First off i went to inline axles/hubs up front, it steers like crazy now and still has plenty of rear traction. I'll check tomorrow but i think i forgot to put the ackerman spacers in the rear so i'll change that for next weekend. High speed steering felt the same and low speed steering was increased more than i've ever felt, there was almost no push or waiting for the front end to hook and turn while going really slow. Not sure if i'll stick with them for the long run but for not it feels like a good change. I'm still 1-1.5 laps behind the leader at the end of 8min though, i blame the driver mostly
Also went from orange front and pink rear to silver front and yellow rear losi BB springs, major difference was more traction in the rear and not being able to jump as far.. if i hit the same jump with stiffer springs it launches my car farther, with a low battery and yellow rears i can't clear a double at our track and case it, even with a good run at the jump. I'm going to try silver/pink and see how she goes next weekend. I drilled my rear pistons with a 1.3mm bit(almost #55, closer to a #2 than a #3) and run 30wt, front is #2 with 32.5wt. Might go with #3 rear and 22.5.
Comments on my setup are welcome, either i've lost the "Edge" that i had when i started running buggy and winning a lot, or everyone else is getting faster in general..Or a combo of both
