I would stay away from aluminum, the filters he posted are good. For shocks i got the one from the landslide 1/8 ultralite on my electric, had em on my nitro and i love them. Worlds better than stock. And im actually gonna put the front 1/8 pro series ones on my nitro volcano. And the redcat tuned pipe is good, thats what i got. And if you want more power get the sh .18, its only 45 bucks with redcats engine replacement program.
