Alright... here goes a head scratcher...

I've got a 2008 Honda Fit Sport currently running the typical "Fit BBK". 1997 Integra Type R calipers up front with 2008 mini cooper SOHC rotors (280mm x 22mm) all on a 4x100 lug pattern. 15" wheels do clear. Specifically a 15x7.5" or 15x8" Konig Hypergram at around a +35 offset. The brakes are strong, but because the 57mm piston is larger than the Fit's 54mm piston, the pedal travels further and some times yields a softer pedal feel.

I'm wondering if NA1 or NA2 NSX calipers will work? I know the brake pad is the same as the ITR caliper. I also assume that the NSX calipers should bolt right up to the knuckle as the ITR calipers do without any modification or brackets. I also know the thread pitch of the brake lines are the same. I'm curious if the rotors will be similar. I've done some light reading on the ITR forums and it seems like it's possible. The NSX's dual pistons are smaller (34/40mm) and should firm the pedal right up. Just want to confirm that rotor would be the same.
