Brake compound upgrade

[GEARBOXGARAGE]

Perhaps this topic has been covered in another post, but as I look through them all, I figured I would post a question to get the ball rolling.

I'm currently running the BP10 pads that came with all of my Wilwood stuff. D52 front calipers on the front, and Dynalite 4 piston in the rear. The vehicle is a '71 C10 Shorty with manual brake setup using a Wilwood 1" master, and I'm looking for a better pad that is better suited for autocross, but still has decent street manners, i.e. low dusting, low noise. Researching their website, I'm looking at the BP20 or Polymatrix E pads, can anyone tell me of their experience with these. From the dyno graph the biggest thing I see different between the 2 is reaction to heat? Any thoughts on this?

I ran Polymatrix E pads on a manual brake system and thought they felt numb. I have tried several others including BP 20 (which ate my rotors) that were much better including a couple from Baer and then some Porterfield R4-1's that I liked the best for modulation and bite. No need to stick with Wilwood for your pads, R4-1's would not hold up on a road course but are great autox pads..

Auto-x tends to favor pads with a relatively high initial bite, good modulation and linear CoF versus temp curve...the low-dust/noise/wear requirements are where you're going to face some challenges. Hawk HP Plus, EBC Yellowstuff, Carbotech AX6, Porterfield R4-1 (as noted above), BP-20, etc., would all be good "GG" friction rated pads, but none are what I would consider to be low-dust pads. I have no personal experience with the E-compound, so I'll let others voice their opinions on that option.

The low dusting is mostly a secondary concern. I want to be able to drive to an event, run the autox, then drive home and not worry much about trashing my wheels. I also go to the occasional car show, but don't know what to expect as far as maintenance and cleaning if I left the more aggressive pads on all the time. The BP10's work great for cruising around and road trips, but would changing pads in and out affect anything, like a cross-contamination of the pad compound?

thanks,

Some pads can be swapped in and out without any major issues, but they need to have similar base matrix materials for compatibility. Otherwise, you can swap the pads and rotors at the same time, then you're guaranteed to not have any problems.

For your D52 calipers try EBC yellow pads. Part # DP41145R
I work for ebc and I use yellows. The are made from Aramid Fibers, IE Kevlar. They are perfect for autocross.

Larger D614 pads (96 Impala SS/Cop car) fit D52 calipers and have a little more surface area if you are looking at new pads anyway.
