I guess I was more worried about the installation than anything. I was wondering what size/type fittings they have on them. Maybe a better question for the company that makes them. The tuning of it is not the problem. My justification for it? I started with a Del Sol S with drums in the rear, and I'll be throwing on the disks from my Si parts car, it already has teg brakes in the front, and I will most likely be moving up to prelude vtec brakes in the front. That, and I'm just completing my engine. D16z6 with a t3 that should be pushing about 15-20lbs. I'm not one to get an engine all hopped up and forget how to stop. If I'm hitting 130+ on a straight, and need to haul my ass to a stop before turn 1, I don't want to be braking half way through the straight just to have controlled braking.
