which brake pads?

[jamal]

CLs are good stuff. The only Hawk compounds I like are their DTC60 and 70 race pads but you need a fast heavy car for those.

You can get Stoptechs in both shapes. On a car like the BRZ they would work pretty good on the occasional track day, and they are a fantastic street pad. The DS2500 is a little better but costs around twice as much.

The D-plate numbers are 929 and 1124 so the part numbers for stoptech pads would be 309.09290 and 309.11240.

XP10 & XP8 going on my car after work today. I don't mind the dust on the street, and they don't eat rotors when cold. So I'll hit the rotors with a flapper paddle and then leave them for street and track.

I definitely can't recommend the StopTech Street Performance Pads for anything other than street driving. I've had quite a few customers come to me after burning them up or with judder issues after trying to use them for track duty. Given, some of those cars were different animals than the BRZ/FR-S, but they are a pure street pads along the lines of the Hawk HPS IMO.

The system should be able to increase braking at one end of the car even after ABS is activated at the other end. That's the whole idea of multi-channel ABS, no?
Way back when my ABS *did* work, it definitely activated on the fronts first.

Same problem with the other cars I've owned, especially ones without ABS or ABS removed.

For sure, any reasonably designed car that never had abs should lock the fronts well before the rears. That is the critical design criterion. I've always found that to be the case. NEVER locked rears first on a stock non-abs system. Never seen it happen. I have heard credible reports of ABS cars with ABS non-functioning or disabled locking the rears first. IMO, these systems should all be designed to ensure that fronts lock up first even without ABS functioning, but of course that don't make it so...

For the S2k, I've heard stories like yours, that rears locked first. All I can say is I've run mine for years with no ABS, with a variety of different pad compounds (always same front/rear), and on a variety of tires (winters to R-comps), under a wide variety of conditions (dry/wet/inundated on street and track, also snow on the street), and I've *ALWAYS* locked the fronts first (not infrequently, either).

I honestly don't understand how/why people are able to lock the rears first on the S2k.

I tried not to use ABS though. My street cars I drove on track only had ABS because they were still street cars. Race car has ABS removed so my habit is to not engage ABS on the street cars when on track either. Getting used to using ABS = failure when I switch to the race car lol

Under braking at high speed on track you've never locked the rears first? Running hawk blues all around on the chump car locks the rears WAY before the fronts so we run stoptech street pads on the back and raybestos up front and it's much better balanced now.. granted that's a FWD car though so not really apples to apples. Most of my track driving is in FWD cars where maybe it's more common to lock the rears more easily without the weight over them?

Did you tell them their website shows the wrong part number? I planned on doing so but I haven't had time to call them.

anyone have any opinions on Project Mu pads?

The MOT of the Stoptechs is above that of the HP+ and close to the DS2500. µ is also in the same neighborhood. For a BRZ that sees auto-x and 1-2 track days a year they should be fine. I'm not saying use them as a track pad. They definitely don't work on track for a WRX or EVO or Corvette or something (and I wouldn't use a DS2500 on any of those cars either).

Ditto. The suckiest suck pads that ever sucked. Orders of magnitude worse on the street and track vs. OEM S2000 pads (which are not good track pads!). Not good on the street, DANGEROUS at the track.

I did not go off their website. had a couple conversations about what platform pads should fit, and those got sent out. I'll take pics and post part numbers in the next blog entry.

Definitely going to be worse than OEM for the BRZ too. I hope people don't try to "upgrade" to HPS.

do you know the right part number for the rears? We got the proper fronts, but not rears. Anyone know what chassis shares our rear calipers?

[ill86]

I will run Endless pads. I have used them for many years with tremendous results.
