Hello all!!!

I am new to the group. I recently purchased a 93 bmw 325is (with limited slip) with the intention of turning it into an ITS car. Can anyone here give me a rundown on the basics of things to do.

I have already replaced...
Shocks (went to bilstien sports for the time being) Control arms and bushings, trailing arms and bushings, sway bar bushings and links, guibo. The drivetrain looks really solid, and subframe is in tact (does not have the reinforcements installed). I am trying to get all the rules figured out before I begin making big changes to the car.

I have purchased the entire suspension(shocks included) and braking system (including master cylinder) from an e36 M3, but do not know which parts I can use and which I cannot. I would love to use the brakes, but from what I read we have to use the stock size rotors and master cylinder. Any advice would be very helpful.

Looking for info on tire/wheel options, roll cages, brakes, seats.....basically anything people can throw at me.
