Trans Brake on a C4

[cucho]

Hello 420nitro, is been a long yeah i now, and also i have my new car running 11.51 with this C4 and a 310 engine, im just use this car for competition non street for the street i got my other stang with a T5 and running 12.70. The thing is that i want more power to leave the line, i got 4.11 and im gone a change to 4.56, with the 4.11 i run 1.70 60 ft at 118 mph, with 26 * 10 slicks, i heard about a planetary sistem for the C4 that came with 6 pinions this increase the relation of the trany or just only take more durability, also i need the servo kit, tell me what i need to do in my C4 already have only shift kit, and also i have a 3500 stall, that works great.
