This system was in my typhon with a Kraton chassis b4 this build. I worked my way up from 25/38 to its current gearingLooks nice! Please be careful with that gearing; I would personally start at 28/34 and work my way up, especially if you don't have enough road to use. You're geared for 130mph+ so you might be taxing your system way more than you need to. Just my 2¢!
