Get some decent track pads on before you worry about the expense of new calipers. The stock brakes on my MR2 turbo can outbrake pretty much anything for a long ol' stint providing the right friction material is gripping the disk.
The Honda OEM pads will be useless. Start with EBC yellow stuff and report back for some more advise
Sound advice
Talking of EBC stuff Tony, those green stuff6000 series pads you fitted on my RX300 back in November, well its 5000 miles on and still can't get those shims in because they haven't worn down enough, not that I'm complaining or owt, actually I'm amazed!!
Me too actually.... Do the brakes squeak though?
Each time Iv'e tried to see if I can fit the shims, and found I can't so put everthing back together, about a day or two maybe. quiete as a mouse now, stops on a sixpence too, mind you I did plumb for the 6000 and not the standard 4000. I'd say they take more stick from an auto, compared to manual too.
And come to think of it, they've not come cheap though, the first check to see if the shims would go in, my mate broke a wheel stud, that got me a 60 quid bill to put right.
