im looking for a set of springs for my slash i have the big bores and the springs seem too soft. i have extra preload clips all the way around and the front seems ok but the rear sags just a bit too much for the amount of preload clips i have in it. the drive shafts are a hint below level which is where i want it for racing but just toomany clips for me. is there any linear springs out there that will fit? well i think they are linear. the progressives seem too soft. and i have rebuilt all 4 shocks 3 times. not sure what to do now.
