im yet to kit mine fully, all i have is the corvette servo. 1-2 shifts are awesome, chirping 2nd. just waitin for my warranty to finish so i can install the kit.
others have only said great things about the stage 2 kit
so can the kit be put in without the box being taken out??
i guess for the professionals i possibly could be done incar, but i'd assume they'd remove it and check everything whilst there installing the kit. personally, i would rather the box out of the car, theres a heap of springs to install.
cant answer that exactly, as im not an auto pro.
