Project Acura RSX, Improving the Stopping Power!

An impact driver is used to remove the pesky Philips screws holding the rotor to the hub.  Then the rotor can be removed.

He the old stock caliper is compared to the new remanufactured Centric caliper. The stock caliper has a phosphate surface finish which mildly resists rust in dry climates like California. The Centric reman unit is bare metal, presumably, the fragile phosphate finish was removed during cleaning when it was remanufactured and will quickly discolor unless you paint or apply heat resistant clear coat to it before installing it.

The Stoptech rear rotor is the same size as stock but is a great quality part that is slotted and has improved corrosion resistance.

The rear rotor is put in place on the hub and the caliper loaded with the Stoptech 304 pads is bolted down.  Then the parking brake cable and the Stoptech braided steel brake line is put in place.

The Stoptech provided rubber-lined brake line bracket is bolted to the OEM location.

Our revitalized rear brakes are ready to go. You can see the anti-squeal shims on the Stoptech pads here through the caliper.

  1. I’ve noticed that no one makes 2-piece rotors for stock sized rotors. I would have thought the weight savings from the iron hub will still be worth the trouble, but it seems that the market does not demand for it.

    Any insights on that?

    1. Because it would be pointless to offer something like that. Stock rotors are good if you are running stock sized tires with stock type compounds. When you run more aggressive tires and suspension you quickly overwhelm the stock brakes in track use, with aggressive pads, the car might stop but the rotors will become damaged, rapid wear heat checking and warping.

      1. are S2000 rotors the same as RSX? Cause there are 2pc options for that… although same logic applies as to why its kind of a waste of money…

        1. Yup, anyone who is really serious about tracking the S2000 upgrades to a BBK now. It only took a decade of telling people that, ha. The crowd of, “oh, I just bring spare stock rotors because they crack every two track days” is much smaller now.

  2. Would you recommend going to a bigger rear brake on a FR car with more even weight distribution, or do they tend to do well with just a more aggressive pad as well?
