ello mate, if you're looking for something a bit better the MB6 front & rear disc conversion will take you up to 282's on the front and 262's on the back, but your studs will change to 4x114.
think you will need rear trailing arms and handbrake cables to get it all to work right.
or you could use EK9 front and rear hubs (i think) that would give you 5x114 stud pattern, again i think you'd need the trailing arms (if you dont have rear discs already).
im currently running the MB6 setup on my EJ9, prelude calipers up front with 282 grooved discs & brembo std pads, 262 grooved discs & brembo std pads.
the next upgrade to that is the 300mm accord brake discs & twin-pot accord/legend/nsx calipers but it's easier to get hold of a pair of new EP3 type R discs, re-drill to 4x114 and then the EP3 calipers fit straight on.
hey presto...a 300mm brake setup, add the twin pot accord calipers, an integra 1" master cylinder (or MB6), some tasty pads and you're laughing ;-)
