Hawk hp plus brake pads

BK911 · BK911's Garage

I did a search and it seems a few people like these pads for mainly DEs and occasional street use. I called a vendor and they said the rears were no longer available, and that most people were using the fronts and OEM rears. Does this sound right?

Its for a 2000# '73 911 with a 3.0 and carrera brakes.

Thanks!

I'm running HP+ in the front with HPS in the rear, so far so good.

Too bad about the HP+, I really liked those for auto-cross/street use..

An alternative would be the Porterhouse R4 (more track) or R4S (more street/auto-cross).

I haven't bought a set in a while but liked them for DE use. I think I got my last set from Tirerack, have you tried them?

Brian,

I think you will be fine like that, a few up here are doing that. The only issue I see with it is the wear differences, you will really have to check them often.

You going to the citrus DE @ RRR in October?

Moi? I have used the R4S pads for street and auto-cross, no track use. They stop and feel very similar to the HP+ pads but seem to squeal and dust slightly more.

I thought BK911 might have been looking for a source for HP+'s. Tirerack website shows them in stock for carrera brakes front and rear.

Thanks guys. I just thought it was odd to use different pads f/r and curious if some salesman was feeding me BS.

Donnie, I am hoping to go to Roebling. I just got back from Sebring and the car ran awesome. Too well in fact, because I have to put a roll bar, seats and harnesses before I go to the track again. Safety first!

The fellow I spoke to at Hawk says the HP+ at 100 f to 800 f to be replaced, and recommended Hawk DTC 30 at 100 f to 1200 f versus HP +. HT 10 are a more aggressive option at 300 f to 1300 f.

For whatever it's worth...

I've found street/track pad, to be a false economy if doing track days. I can burn up a set of HP+ pads in a weekend. On the other hand, a set of PF97s will last all season (25 to 30 days). I used to swap them out for street pads. But since the cars isn't driven a lot on the street, I simply leave the PF97s on all the time.

What is the down side or what is it like driving the 97's on the street?

Squealing noise when stopping.
Pad "knock back" sounds when turning.
A bit more rotor wear than with street pads.
Most importantly, high-speed panic stops are non-linear. (Exactly like what happens when you brake hard, on cold brakes, on the track. The tires lock up.)

I have to think that Hawk is reacting to market demand. Most people I know that tried using the HP+ as a combo street/track pad discovered that it did neither well. Lots of noise on the street, marginal for intermediate track use and useless for serious track duty. I can cook them in 20 minutes on the track.

Frankly, it's so easy to change pads in a 911, why not just have 2 sets of pads? HPS for street, Blue or HT-10 for track. And don't forget a good high temp brake fluid.
