One word ALKYControl. period Best Bar none. Nothing agaist the other kits they are good but AlkyControls are the best. & if you have questions on it just contact Julio himself, he isnt hard to get in touch with.
Got one on my TTA went 11.39 in it with pump gas, and will soon be getting one together for my Daily Driver AWD Turbo Laser.
