JB4 Freight Train

I just put my JB4 "stage 3" on last night and I am all

I had the JB4 on my 135 before I sold it and the chassis and suspension never seemed to handle it well. Everything seemed to squirm under hard acceleration.

The 1M on the other hands just squats and goes. This is definitely how the car should have come from the factory. This has me drooling at the prospect later on down the road of RB upgraded turbos, catless DP's, and FMIC. Oh if only money grew on trees......
