Racing Brake Pads ?

Hi,

I race in Australia in a class called 'Improved Production', I am after info from people re what they would recoomend re brake pads. I currently run Hawk Blue's (Gen 2 front end, Gen 1 front end, disks all around).
I run HB158 and HB 155, any other recommendation on pads, and what is the price in the states for Hawk pads?

Cheers.

Nothing wrong with Hawk Blues. Hard on rotors, though...Blues AND Blacks cause heat stress cracks after multiple events.

Blacks are $150, and slightly more for the Blues...these are front pads for the FD Rx7s.

This year, I'm trying EBC Reds up front and Greens in back.

There was a pad that the Triple M Mazda Rx7 SPs used to great success in the '95 Eastern Creek 12 hour enduro. The Mazdas never had to do a brake pad change during the entire race, while the Porsche 993s RSCSes DID! I think they were called Endless Brake Pads? I have a great video of that race that Mazda Australia sent me. I have pics of the production SPs as well in black You Aussies really love your Mazdas!

Hi,

Yes Mazdas are big down here! Even though we have heaps of V8's as well we sure have some great races!

Today I am not, watching it on Tv, but yes tomorrow I will go! I just watched the V8's race, real cool. Now all I need to do is learn to drive my Rx7 as well! Next weekend is my first race this season.

I'm wondering, will that mix of the greens and reds cause weird handling under braking? As I understand it, the greens are a bit more grippy than the red, but the red are much more fade resistant. I imagine this would cause a shift in your brake bias as they heated up...

Gene,

Yes, your concern is noteworthy.

I'll start with the stock '99 Type RS brake pads first to see how they fare. If they're fine, I'll stay with them the whole day. (I'm retrofitting '99 Type RS brakes on to my '93 US spec R1).

If the stockers start to fade early, I have the EBC greens set up to run all the way around to see if that works better than the Type RS stockers.


I've been rethinking the reds. The reds are a slightly different pad material than the greens. The greens have a high kevlar content, while the reds are semi metal pads. The friction coefficients are also different. The greens have a much higher coefficient and is heat stable up to 1000 F. The reds have a lower friction mu, but the mu rises steadily as the heat rises above 1000 F.

I don't really know how the pads will fare at the track with the larger '99 Type RS brakes. I might be fine with the stock '99 Type RS pads (which will be great, since then I won't need to swap from road to track!).

Full report coming once I test at Putnam Park on March 23.
