Right, I knew about the scarebird brackets to avoid swapping over entire trailing arms. Their ebay price is higher than their website which is only $74. Then just add the cost of parking brake cables, 40/40 prop valve, maybe larger MC.
I'm already running the ITR front caliper 4 lug with the mini cooper rotors. Perfect fit and no problems for a year including track time. Before that it was redrilled Prelude rotors and shaved brackets.
I started the thread asking if anyone has confirmed using Accord/Prelude rear brackets to make it possible to bolt the DA/DC rear caliper on a 10" EP3 rear rotor and use rear ITR pads. I've already swapped over the entire EP3/RSX-S caliper+bracket on two of my Integras so this would be for others looking to not deal with the hassle of inverted rear calipers and the general swap. Upgrading the rears makes a huge difference, even with factory 10" fronts it helps balance the car out a lot.
I can easily out-brake street tires, but works well threshold braking with my setup.
