are there any serious drawbacks to installing front na2 calipers and rotors on a na1 car, leaving the rears stock? would the master cylinder be terribly unhappy or the f/r bias be totally messed up?

na2 front brakes on a na1 car

Isn't that the same setup (NA2 front and NA1 rear) as the 2002+ NSX-R?
No the NSXR had NA1 front NA2 rear to move the bias rearwards.
Hi,
i thought that the NSX-R had NA2 on the front... 300mm... or is NA1 calipers with NA2 300mm size rotors?!?

The NSX-R has a different weight anyway.
NA2 moved the brake a little to the rear but not by much. But the NSX the front ones have a lot to do anyway compared to Porsches and other younger cars. The NSX lacks an electronic distribution control which is standard for todays cars.

Modern ABS systems allow for more rear bias, because the computer has more line pressure to modulate lockup. In many new BMWs and Porsches, removing the ABS with the stock master/calipers = significant rear lockup.
Changing the pads Front to Rear can combat this, or any difference between NA1 vs. NA2 front caliper.

As the new ABS system was installed on 99+ the 97+ brakes don't improve the NSX F/R ratio significantly. As the year flew by...
I compared the brake temps of the NSX and GT-3 brakes during a drivers course and the NSX brakes in the rear were disturbingly cool compared to the GT-3 ones while the front ones of the NSX were also disturbingly hot and stinking.
Improving NSX brakes is more improving brake distribution than mounting bigger brakes but as the first one involves engineering the second one is the route most have to/will go.

Depends on the suspension (springs) you are running and the pads.
When I ran HP+ F/R the rears were much hotter than the fronts. Carbotech XP10 & XP8 rear - they were even.

Why the springs?
The car I observed had OEM pads (91). Mine has HP+. I'm astonished you observed hotter rear brakes. Will test it on my car. :wink:
Wait, let me think. Don't you have custom ducting to your brake discs?

Newer Porsches squat in the rear under braking while the NSX seems to have more front dive (more front bias). The front brakes still do the majority of the braking, but yes, adding slightly more rear bias to make the rears work a little more would help.
