Does anyone use the Porsche Sport Pads for street use? I've done a search but have only read of 02 Carrera's impressions: https://rennlist.com/forums/showthre...38#post3415038

I need to replace my brake pads (street use only), but instead of the standard OEM pads, I picked up a set of the Porsche Sport Pads which are stamped Textar T4128, part nos. 99635298000 and 99635198000, thinking that a more aggressive pad with a higher coefficient of friction may help increase the rate of decceleration if I hit the brakes hard while on the street or highway.

Is my assumption correct, and if so, do the Sport Pads fit the bill or should I stick with the OEM pads? What do you gain or lose by going with the Sport Pads instead of the OEM pads?

Various posts praise the Hawks, Pagid S (Blue), and MetalMasters. Do any of these fit the bill better than the Porsche Sport Pads or OEM pads?

Thanks in advance.

I would suggest giving a call to Ruf Autocentre. Both Wayne (on his Boxster S) and Hans (on the Ruf Kompressor 997) run these pads on their personal vehicles for a 2nd opinion. Keep also in mind that Texttar and Pagid are 2 different brands produced by the same company.

let us know what you find out! I hear the Textar stuff is pretty good... again depends on what you want it for... I've heard good things about the Porsche "sport" pads...

What are the friction ratings of these pads? There should be 2 letters on the back of them.

Tool Pants: In white lettering, the back of the pads read:

TEXTAR T4128 (47A)
21942 170 319
996.351.940.30 (note: 996.352.940.30 for the rear pads)
Germany 437387 09/04

Stamped into the metal backing of the base of the pads is:
TEXTAR T4128 21942 (47A) 02

What does that tell you?


02 Carrera: Thanks for the recommendation.

Look at the pad at the top of the picture, which is a Boxster Textar pad.

Stamped on the metal backing plate and in white letters is Textar T4045 FF. FF is the cold/hot friction ratings. 2 letters are used for the ratings.

The Galfer pad at the bottom of the picture is also rated FF.

Are there letters on the back of your pads?

Tool Pants: There are no letters stamped on the pads.

Tool Pants

Don't know what to tell you.

Even the Hawk pads we use have ratings, such as GG in the picture below.

Notes on rating of pad friction: Pad Friction levels are designated by the alphabet system... the further down the alphabet the higher the friction level and double letters is stronger than single letter designations (for example: GG has stronger friction than G rating).

Tool Pants

That is 1/2 correct.

First letter is cold. Second letter is hot. The letters are not always the same.

On the left is a FE aftermarket pad that we put in a Boxster.

So what would be a good rating for street pads, and then street+track pads?

Tool Pants

I am no expert on this subject. All I can tell you is what we have put in over the years, and maybe avoid some of the marketing hype.

Those G and G rated Hawk pads are popular with the autocross crowd. They can make noise on a street car and need to be heated up to bite the rotors. But they can be a dual use pad.

You do not put true "racing" pads on a street car.

For the street E or F work. On the Box Porsche uses Galfer FF on the front and Textar FF on the rear.

My fronts happen to be a Mintex with an E and E rating. My daily driver.

In any event, I think the point of this thread was and should be the coefficient of friction ratings. Calling a friction material "sport," "performance," "old lady" is just marketing without the ratings.

Thanks Tool Pants. It's always nice to learn something new.

Hey Russ, did you also put red stripes on your brake pads?

Russ Murphy

No, but you got me thinking about it now.
