which pads are you guys using with your Stop Tec slotted rotors?

PFC 01 on Stoptech fronts.
Hawk blue on stock rears.

SO I guess Brakeman 3 was a bad choice? My stop tech rotors look like they have minor cracks around the whole rotor after Pocono last week. I'm not doing anymore track time, so I'll just use these till next season.

BM3 not necessarily bad. I've run them on the rears. But I love PFC 01.
Minor cracks are normal. If the crack extends to the edge of the rotor they need to be replaced.

Chuck, arent the PFC01's too aggressive for the non-ABS Viper? i used them on my old race prep'd 350Z and they were great, but i thought they would be too much for my viper. I tried the carbotech XP10's and they were WAYYY to much grip in the front for me.

BM3 on & off the track.

Eric, depends on driving style I suppose. I love lotsa grip. I'll have to try those carbotech XP10's. Do they make them for Stoptech?

I have stock fronts and 40 mm rears... switched from BM3 up front to PFC 01 and now have a habit of locking the inside front wheel. Still have BM3 on rears.
Definitely more stopping power but flat spotting a tire daily. More difficult to modulate than BM3 IMO.
I have a set of carbotech in the box for the front to try but if these bite MORE, I won't even try them.
I'm gonna try to be a little more delicate with the brake pedal and try the PFC a little longer since I just put a new set on.
Chuck, if I remember correctly, you have the front Stoptech calipers which actually have a little less piston area compared to stock along with Tom's 38mm rears?
Perhaps the PFC's work a little better with the balance you have... or, you may just have a better feel for the brake pedal.

I do my share of flatspotting. Less and less over the years. But that's the price to pay for learning to stop on a dime. You just plain ain't gonna do it without a grippy pad.
I lay on 'em hard at 150mph and as the car slows I gradually back off.
Too much camber will lend to flat spots as will improper weight distribution. Have a pro scale the car with you in the driver's seat.

And while we're at it what fluid are you using? I think I still have the stock stuff and lost my breaks by my third run at Summit Point.

Castrol SRF. Don't waste your time or money with anything else. I've already done that for you.
Change your fluid no sooner than one week before each event.

Chuck, your right there, key words are CHANGE FUILD before EVERY Track EVENT

I have a fairly new set of XP10's for the stock fronts if anyone wants to trade or try them i'll sell them for half of what i paid or trade for something a bit less grippy.
only have 1 track weekend on them
I will go with XP8's in the front and XP 9's or 10's in the rear.

PFC 01's are the most popular with the Stoptech equipped cars at Viper Days.
Have not had any brake fluid problems with Motul RBF600. Castrol SRF is also excellent but pricey. Either way, flush the dark fluid AFTER each event, and have fresh fluid throughout BEFORE each event.

Chuck, that's a good point about the camber.
The car is corner weighted but camber is set equal (-2 deg in front, I believe) on both sides despite that most tracks I have run on are clockwise.
Flat spots are definitely on the inside aspect of the inside tire... some trail braking doesn't help.
There's obviously a tradeoff on the camber. It would be nice (if I were competitive enough among other things) to adjust alignment for each track and have someone check my tire temps to better hone this.

Aint that the truth. First buy a car, then get helmet, then a trailer, then spare sets of wheels, a bigger tow vehicle, enclosed trailer, tools, tools, tools, tires, tires, tires, etc, etc, etc.
Now we're at the point of bringing our own dedicated pit help.
It never ******* ends.
