332ti track brakes and tires

[Speed25]

New owner of a 332ti that I'll be converting for mostly track use. The car already has the e36 M3 brake setup, and stock rears. Any advice on a good pad combination? Will stock rear calipers and rotors hold up okay? Will get SS lines and RBF600 fluid.

Also, tires. I'm planning 17x9 LTW5s with a square set up. I've been running a 135i that needed tons of work to eliminate understeer. Since the Ti is known for oversteer (e30 rear), and it will be partly gutted (very light in rear), is a square setup still what I want?

Thanks for any experienced help!
