I am doing a mass purchase in a couple of months and need some help with what gauges I should get. I will have room for four 2 1/6" gauges. See my sig for my current mods. At that time I will be purchasing the following, Kenne-Bell 9psi intercooled kit, steeda shifter, upper and lower control arms, a roll cage, aluminum drive shaft and safety loop, a set of 16" rims and drag radials, shocks, struts, springs, caster/camber plates. Suggestions please.
