I'm trying to get my '87 ready for a couple of late summer DE trips. I want to redo my brakes. A friend of mine races cup cars and recommended that I use just plain, slotted rotors, no cryo. I found Power Slot rotors for a pretty resonable price. Anyone have any experience with them? My friend also recommended Performance Friction pads but they don't appear to make them for the '87. I was thinking about the Pagid Orange, any other suggestions?

Thanks,
Paul

I use Performance Friction Track pads (compound 97) and love them! OG Racing s great to deal with, and is a sponsor to boot. Call them ...if they make them for an SC, I'm sure they make em for a Carrera. BTW, the ATE rotors (with an elliptical slot) is really good, and is priced reasonably, and the PFC-97s are also less pricey than the Pagids. Hope this helps.

Hi Paul:

Love the color of your car!....

Power Slot rotors are just fine as well as the ATE ellipically slotted ones,.....I've used the ATE ones on my daily driver for 10+ years.

Brake pads are a matter of preference so Edward's suggestion of PFC 97's as well as Pagid Orange's will do the job very nicely for you. Additional brake cooling is strongly recommended for DE events.

Paul,

The ATE rotors with the swirly lines are great, however, I'm not sure they make them for the Carrera's (think they are only good through '83).

If you're just starting out, I might gently push you away from Pagid Oranges. They are great pads which I've used for years (but am switching to PF97's). The Oranges require careful bedding per Pagid recommendation. If you don't do that, they seem to be more prone to deposits on the rotor, which mimics a warped rotor. I haven't had that problem, however, I've bedded them properly and always used slotted rotors (not sure if that has an effect on pad deposits, however, also have never had any). Overheating the pads can also contribute to pad deposits.

My Performance Friction listing shows PF97 fronts for 75-89 911's as 0045.97.15.44 and rears 0031.97.15.44. I've posted in the racing forum PF's recommended bedding procedure.

Heat is our enemy at the track, and as Steve points out, additional cooling is good (removing the rotor backing plate is one way to get more exposure to air, but isn't a cooling solution by itself). Don't aggravate the effects of heat by pulling in after a run on the track and using your brakes to stop when you park. Your rotors are real hot, and you're resting the pads directly against them, sending heat thru the piston to the brake fluid. Instead, as your pulling up to your parking spot, be in first gear, push the clutch in, turn off the engine, and feather the clutch to stop. After parking, don't put your foot on the brake and don't set your handbrake.

Thanks All!

Bill, what is a good source for those PF97 pads?


Best regards,

Paul,

As Edward did, I ordered mine from OG Racing. They are good people to deal with, have reasonable prices, and have a good selection of 'stuff' of interest to those who visit the track (unfortunately, pads can't be ordered online). I found that there is generally not much discounting on the PF pads.

I had the Power Slots on my 83SC for three years, really liked them.
I had one DE and about 50,000 miles of fun driving on them.
I went though two sets of tires and one set of pads (Mintex)
The Power Slots held up well and looked really cool. !
I decided to go with the Zimmerman cross drilled on my 89
with the PF pads. Just thought I'd give 'um a try.... so far
I like 'um.
Good Luck
Chuck

Thanks for all the help guys. I ordered the Powerslot Rotors from AJUSA (Great Prices, free shipping BTW!), new SS brake lines from Zims, and the pads from Brian at OGRacing.

I found the bedding procedures at Performance Friction for the PF97, any caveats or changes to that procedure I should use to bed the PF97 pads and season the rotors? I will prob. not have access to a track for a few weeks after I install the new gear.

Also, Brian strongly suggested that I only use the PF97 pads for/at the track and change to a street pad in general. I would prefer not to mess around changing all the time- how scary will the PF97 pad be around town and how much wear will I see if I do use those pads all the time?

One of the reasons I like the Porterfield r4s. Works great on the street cold and great on the track when heated with minimal wear. Go too hard (like the PF97) and your first stop in the morning can be a little long - and a little panic inducing... Hey it will wake you up in the morning - who needs coffee?

You can drive with PFC 97's on the street, but they don't stop as well as a normal street pad without some heat in them and they will leave a lot more dust. They also wear quicker and are expensive. My $.02 would be to change back to your street pads between track days. It takes around 10 minutes and is well worth the time. It also forces you to have a good handle on pad wear. It would be a bummer to wear through a set of pads at the track and have to deal with it there.
