Two thumbs up. Best bite & pedal feel, very good wear (we changed only the fronts once at the Thunderhill 25 hour). I don't think you can go wrong with them. Plus I'm pretty sure they give a discount to BMWCCA members (http://www.cobaltfriction.com/carclubs.htm), so ask about it when ordering. Side note, overall winning car at Daytona 24 this year was on Cobalt pads. Jeremy Lucas 95 M3 - now with Cobalt pads ----- Original Message ----- From: "Fernando Mujica" <fmujica@mac.com> Don't ask me how, but I ended up ordering Cobalt SpecVRs front and rear for track use. See info below. So, I guess I'll be the guinea pig :) From Cobalt's page on the SpecVR... Coeff. of Friction: 0.64mu Temp Range: 350-1550F+ Cobalt spec(VR) is a GT-Class road racing compound delivering unparalleled initial bite and braking torque, with excellent modulation and release, a very linear pedal feel for consistence performance, and extreme fade resistance. The spec(VR) has a flat torque curve, with a coefficient of friction of 0.64mu, up to a fade point in excess of 1550F. Additionally, the spec(VR) is surprisingly rotor friendly, and has excellent wear rates. Suitable for all GT-Class vehicles, as well as Formula Cars (Atlantic, Continental, Mazda, et al.), and Sport Racers (Radical, Stohr, WSR, et al.)

I've liked and used PF90's, then PF97's for many years, but didn't realize the corrosiveness of the PF97 brake dust until I drove home from LRP in the rain last year on street tires, which were on pristine M Contours. It's no problem unless it gets wet and then dries caked on the wheel as it did on this trip. I also experienced serious heat-related brake fade at the Summit Point enduro last year. If I'm going to put up with the dust of doom anyway, I'll go with the racers' favorite Hawks, which the Bimmerworld folks tell me have noticeably better heat-resisting qualities than PF97's. Now, they sell Hawks so they're prejudiced, but they also kick tail in ITS (and not shabby at other levels) with no brake problems at all. Hmmm. (HEY, why aren't they a list sponsor?!)

I recently tried Carbotech Panther Plus, XP9 compound, I think. I was very dissappointed. Did not have near the stopping power of the HB's and they wore much faster. I got them with the NASA instructor discount so I may try their XP10 compound before giving up completely on them.

Date: Wed, 11 Feb 2004 09:14:02 -0500 (EST) From: marc@plante.com Subject: Re: [E36M3] PF 90/97 Brakes...PFZ? I've been a long(ish) time user of the PF pads, including 90s and 97s. Only other "track pad I tried was Turner's Cool Willies, which ran clean for a track pad, but didn't have much bite. Regarding Chester's vibration comments. I and other drivers have had similar issues. It seems to be a function of the pads laying material down on rotors and bedding in. A common solution to this is to swap rotors with pads and have a set of rotors that are bedded to the pads. For some reason, I find that hammering the brakes relatively hard a few laps into the first session (after warming them up) helps to get material into the rotors and smooth out the shimmy. Once they're bedded in, they are consistent with good bite and life span. The problem with melting seals probably comes from the fact that the pads hold more heat than stock pads. My mechanic keeps telling me I need to duct. I just replace seals, though when I take over my wife's M3 as a street car and migrate the 325 to more dedicated track use, I'll probably duct it. One of NCCs geekier instructors (Pete Read) called and talked to people at Performance Friction about the 90s vs the 97s since a lot of DE people loved the 90s and are not as keen on the 97s. The 97s are designed to run at a higher temperature range, which cuts the low temp driveability that the 90s had. I think the 90s were rated at something like 1000 degress while the 97s were rated at 1200. Personally, I find the 97s have a bit more bite, though they're not as happy shuttling to and from the track as the 90s were. I miss the 90s, and would love to find a pad with similar characteristics. Marc Plante E36 325i, 218k Vienna, VA

#6. Mounting question on hybrid GC camber plates... - from AVUSM3@aol.com
Top
Date: Wed, 11 Feb 2004 09:27:59 EST From: AVUSM3@aol.com Subject: Mounting question on hybrid GC camber plates... Hi Josh - You are right that the bolts on the GC plates have an allen head. What is not obvious in the picture is that these bolts are welded to a frame/carrier which goes under the plate. These welds hold to bolts in place and allow you to tighten the nuts on top of the strut tower. You should have no problem running a strut brace since I am currently using a LTW brace with these plates on my '95. One word of caution - be careful with the amount of torque you use to tighten the nuts on top of the strut tower. I believe the spec is 13 lbs-ft. The welds that hold the bolts to the frame/carrier below cannot take much more than that. Ask me how I know......I managed to break one of the welds while installing the plates and needed to have the bolt re-welded onto the frame/carrier to complete the install!

Have a set of these coming to me and I have a question on how they mount. Do they have studs like the factory bearing plates so you can still run an upper strut brace? On the GC site it looks like they use allen head bolts that bolt from the engine compartment down... Although I suppose I could use bolts up through the bottom of the strut tower up, then through the strut brace... TIA! -josh

I ran 255/35-18 on rear and 225/40-18 front. I had about 15K and one track day on them when I sold them and upgraded to S03s. My guess is they had at least 5-7K left on them.
