Hey guys. I was curious if it would be ok to put front discs in the rear for a thicker rotor. or have rear discs all around to save weight?
Front rotors in the rear and vice versa

Why would you want to do either one? 
The engineers of the NSX (as with most other sports cars) designed the front rotor to be larger because most of the work during heavy braking is done by the front brakes, due to the transfer of weight from the rear to the front.

Sort of a big brake upgrade for the rear. more metal means better heat absorbtion and less brake fade. However if i switch to thinner rear brakes for the front, yes, i would induce greater brake fade but i would reduce my rotational mass making the car turn better and easier.
After analyzing the front and rear rotors. they are the same diammeter. the hats are too. Only difference is 28mm thickness and 21mm thickness. The only thing I would be concerned about would be:
1. Can the rear calipers accomodate such a thick rotor. if not then how about Integra Type R front rotors. they are 11 inch diammeter but are 23mm thick instead of 21mm.
2. If I use the rear rotors will the front caliper pistons have to reach too far to make contact? However many Integra and civic owners use Integra Type R rotors with the NSX caliper. So it isnt too much of a reach from 23-21. Just something I was pondering.

BTW: There are differences in the bore for the hub, unless you have some magic that allows the hub diameter to be changed, as such one set of rotors will put stress on the wheel studs and for the other they won't even slide into the hub.

The shape of the caliper will not allow this in the rear.

exactly. sounds pointless and quite dangerous to me.nsxtasy said:Why would you want to do either one?
why dont you just get a big brake kit if you want better braking? i have seen in a couple magazines of people custom putting a front rotor and caliper setup on thier rear. i seen a civic and a jetta with that done. i would never even think of tryin it on a nsx
I have a better suggestion: Why not drive in reverse all the time? So you will have profit of the lighter rear rotors :wink:hlweyl said:If I were to switch front and rear rotors, I would switch the front and rear tires as well.
Wow,
I havent heard of a bad idea like that in a long time.
Very dangerous because your messing up up brake balance and when going through hard braking the weight of the car shifts forward. This will increase the strain on the small brakes then in the front.
Shifting them around will not change the weight either.

Why don't you try using some StopTech front 2 piece rotors and since they are 2 lbs. lighter that would solve your rotational mass problem for quicker turn in. 
For the rears just go with some good quality slotted rotors such as SP or Rotora and don't worry about the weight but rather about how well they'll be cooled to preserve pad life.
In this fashion you will know everything fits, and will only improve your braking and rotor life without getting into complicated untested switching of mismatched parts. :frown:
Good luck but be practical here.
