Thread: Brake weights

Anyone know what the differece in weight between the different brake setups are?
I would like to know aftermarket and OEM options.
For example ..Are NX calipers heavier than Willwoods.
Rotor weights,slotted,or drilled,etc.

I feel this info will help out with anyone building a racecar or trying to trim pounds off a street car.
I am not saying to run lighter brakes and have less stopping power,but maybe the weight may factor into your decision on upgrades.
I for one am building a track car that I want the lightest possible brake setup without sacrificing performance.
I would like the stopping power of nx brakes at a minimum,but lighter if possible.

I just did the nx upgrade on my 200sx and I'm disappointed, besides weighing about 10-15lbs more per wheel they don't stop as good, but then again I didn't upgrade the mc yet

Something is wrong. I kept the stock master cylinder, night and day difference.

Did you properly break them in?

Wilwoods are like 1/3rd the weight of stock brakes. They are all aluminum instead of cast steel.

This is easy. Get the LARGEST rotor (2 pieces are usually lighter)that you can fit and get the SMALLEST pad/caliper combo (wilwood and brembo make tons of calipers for custom applications) that you can find that still has brake life to make a full session. That will get you the most performance and also be the lightest. Size of pad has nothing to do with brake performance.

Hmm, maybe I should add this info to my thread.

Also for track use... Ditch all the parking brake crap. You don't need it and shouldn't have it on there. All it will do is tempt you to use it in the paddocks and ruin your rear rotors (when I come off runs my brakes are literally smoking). If you still want to have a parking brake you can get a ball valve inline to the rear (stomp on the brakes then close the valve for parking). You can ditch some weight there pretty easy.

Any suggestions for this?
Are you running a setup like this?
Right now the car as ad18s on the front,but I was thinking about leapfrogging the NX upgrade for something lighter...like maybe 11" wilwoods.
I also already have a set of P10 rear calipers for a rear upgrade if needed later on down the road.


I already bumped that thread for this


Thanks...Any actual comparison #s available that you know of?



Good idea,bu then I cant drift...J/K
Thanks for all your input...keep it coming

I race a miata... So I can't say specifically what will work for you (at least bolt on directly).

To fit under 15" wheels I am stuck with 11" rotors (which if you want to run 15" you will be too, which you probably will want to). I prefer Brembos for how the brake line attaches with banjo fitting, but either way you are going to have a good setup.

If it were me I'd run 4 piston calipers with 11" 2 piece rotors in front (I personally like to have plenty of pad vs saving the last nth of weight). And 10.5 to 10.75" 2 piece rotors in rear with a 2 piston calipers (or move current front brakes to rear to save money). Get 7/8" or 1" MC and balance valve then be golden.

Has anyone been able to find out how much more the AD22 setup weighs over a B14 setup? The 10-15lbs per wheel mentioned above sounds like like an estimate.
