you mean with normal propulsion (meaning bolt ons only)? adding 50+ whp/wtq makes it a completely different ballgame

when i'd run my wagon with just 4 lbs (about +50 extra hp) and i had race pads (performance friction) and some good blanks with ate fluid and ss lines i'd have brake problems...when i'd turn it up to 7-8lbs (~190whp and ~205wtq) my stock brakes just couldn't handle it...what made the difference was upgrading the rotor to 11.2 inch from 10.5 inch and thickness from .53 mm to .85 (mazda rx7 size) made the biggest difference as the brakes could effectively cool themselves...i'd literally be running high 130 mph straights into a very tight turn one at summit point
