Duke, I've driven a stock 2.3L, a stock 2.6L, my euro 2.3-16 and a 2.6L with 400E front brakes. Hands down, the 400E brakes are the easiest stage upgrade to the chassis. I'm glad you find your brakes adequate . . . so just imagine the improvement. I'm also familiar with that "cheese grater" of a track formerly known as Firebird Raceway. It's now Wild Horse Pass The bigger brakes make taking that hairpin just before the dregstrip a much faster corner, likewise the looper at the end of the strip.
