It's pretty much like doing TypeR front brakes upgrades on a Civic/Integra. U cannot use the stock fit brake rotors coz those are regular civic/integra's size which is in 262mm/10.3". U need get a pair of 282mm/11.1" size Prelude rotors (redrilled 4x114.3 to 4x100 pattern) PLUS a set of TypeR size brake pads & a set of 3mm spacer behind the brake rotors.
For wheels clearance wise, there are some 15" wheels out there like these Team Dynamics ProRace1 will clear even with 15x7" +45mm(4x100) offset. U can get them from fastbrakes or good-win-racing.com:
Other choices out there that should clear are(list below are the 15" wheel choices for ITR/CTR, u may need to add another 3mm extra room on offset):
- [15x7] Kosei K1 15x7 (+38mm offset)
