A Legend owner has alraedy put the Compech big brake kit on his Legend. Here is the problem, COmptech had to machine a special extention braket for the calipers, and I believe that actually had to do it twice for him before they got it to fit. However, after that, I believe he said Comptech had enough with that, so they would no longer to that for anyone else. Thus, it is possible to use the Comptech RL brake kit, but you will need to find your own shop to fabricate the entention caliper brakets.
However, the more I hear about it, the more I really believe the guys who says the NSX brakes and caliper will fit the Legend. The 91-96 3.0L NSXs use an 11" rotor like we do, so their caliper might be a direct fit on the Legend. If not, maybe a minor modifications. Now, if that is so, then the 91-96 NSX brake kits should fit the Legend as well. We just need to find someone who has the money to experiment on this one
Or, just confirm with someone who might have already tried it.
