> I need to replace my front brake pads soon. What's the general opinion here, should I stay with the Porsche ones or go with something else?

The 928.... part number pads for MY 86-91 have since been superseded by p.n. 993.351.939.01 (front) and 964.351.939.03 (rear).
I had the fronts replaced a year ago or so, and they have been put to
the test on our common venue, the Autobahn, many a time to my full
satisfaction (not to mention the Nordschleife - Hi Jay and John!).
Would you want to gamble on a recommendation by someone who rarely
sees the fast side of 80 mph??? Take the Porsche recommended pads.
They dust a bit but never squeal (unlike some passengers).
I can't believe that none of the 928 rennlisters experts bothered to reply to your reasonable request for information on a 928 matter instead of all that dribble about Russian Sheep and French Sex ..
I am not a mechanic but, I believe your 928 GT 1990 has the following options.
Porsche part number: 928 351 939 02 without asbestos - model M475
or with asbestos 928 351 939 03 - these are the same pads for the 87; 88 and 90 928.
You may also consider replacing part number: 928 351 927 00
I usually use part no. 00 043 117 00 as a preferred anti squeal paste.
Also sometimes part number : 928 351 950 00 must also looked at.
Another trick that Wally once mentioned was to have the pad material facing inwards. Gives better braking results than others. Sheep skin is not a good braking material but has lanolin as a natural lubricant.
The part number : 965 352 939 03 are the preferred pads for the rear brakes.
Graham, I hope this has been a help.
I think Carlos has advice on how to fit them without spending to much time away from the Net.
I am doing ok. Thanks. I kind a expect summer to come soon since it is getting warmer by the day ;-) (we had 10C today). I hear about the Textar being actually quite good. Not too much dust and good braking friction. The price of 118 EUR is really ok. Make sure you get new dampers in as well. They glue at the back side of the pads.
Here is my "simpelton's explanation" of brake compounds.
Hard ones work best when hot. Soft ones work best when street temp (cold) If you use hard (race compound) on the street, they never ever get up to the proper temp, hence they have little stopping power...but, hey, you gotta stop...so you push even harder, and finally you get her stopped. Next corner, next off ramp, same deal. It is like pushing a piece of concrete against the rotor...push hard enough and it will eventually stop you, but it's hell on the rotors.
If you use a soft street compound at the track, man, your first few corners feel great, because the pads are right smack on their best temp...but a lap or two later, they be too hot .. no matter how hard you push, they don't have the right grip, they get even hotter, then the fluid gets hot, then....
So, on the street, use the right pads and you won't have to trash your rotors.. On the track, use the harder ones because after a few laps, your rotors and pads will be too hot for a street compound to work properly. Or if you are DEing, you will want to back off for a few laps after a couple of fast ones.. let the pads cool down before they get the fluid boiling, if you're running that hard with street pads.
