Bashing

shocks are way to soft lol, im gonna get some 70 and 80wt oil so that its nice and firm for jumps. Im gonna make an order from tower and want to know what spur i should get, im not gonna lock it into second so i'll have both gears. Im probably gonna get a 8xl or 9xl, it will be running on 8 cell ib3800 packs and also a couple of 7cell gp3300 packs. I would like it to reach around 40+mph, in second gear of course lol. Thanks for any help:)
