Hi everyone,
I thought I'd share this with you all, but current StopTech owners and prospective buyers will be particularly interested in this one...Here is a copy of a press release from our website, and some pics. In short, our rotors went the full 25 hour race distance at Thunderhill (560 laps for this car), plus an extra 100 laps of practice and qualifying. The brake system on the Bullet car is made from the same exact components that are on our street kits for the Z. Obviously, the part sizing is slightly different, but our racing and street kits are made from the same pieces. I thought you guys might enjoy seeing what your kits are capable of.![Big Grin](https://my350z.com/forum/images/smilies/biggrin.gif)
StopTech Rotors Enable a Class Win and Go the Full 25 Hours of Thunderhill
Torrance, CA… It took five drivers and only one set of StopTech AeroRotors® for Bullet Performance of Costa Mesa to win their class and place 8th overall in the ultimate endurance race - the 25-Hours of Thunderhill. Seventy-five race cars, including top teams from around the country, took on the challenge of the race dubbed the “new king of enduros.”
Bullet Performance ran StopTech’s World Challenge 322x28mm brake upgrade on their #56 1996 BMW 328is. At the 12-hour mark, the team was leading their class and 7th overall. “The StopTech brake system performed great the entire race with negligible brake fade. We were able to continuously brake deep into turns,” said Chris Welch, one of the five drivers of the Bullet team and co-owner of Bullet Performance. “It was unbelievable that not once did we have to change our rotors or pads during the 25 hours of non-stop racing, and this reliability allowed us to save time and increase our lead.” According to Mickey Miller, driver and co-owner, they completed 560 laps in the race and 100 laps of practice and qualifying on the same StopTech rotors.
After starting the race at 11:00am on Saturday, Bullet Performance took the checkered flag the next day at 12:00pm. StopTech’s front-only World Challenge brake upgrade kit includes two-piece floating directional AeroRotors® with directional AeroHatstm, ST-40 4-piston calipers with patented bolt-in bridge, and StopTech stainless steel brake lines. The team ran Hawk HT-10 track pads in the front and had a third of the pad remaining after the race. The low pad wear evident in this grueling race was a direct result of StopTech's superior AeroRotor design. The tremendous air flow through the patented internal vanes and directional hats allowed the rotors to stay cool enough to keep pad wear to a minimum.
The World Challenge brake upgrade is designed for 55 minute sprint races and the rotor is smaller than the standard StopTech 332x32mm BMW E36/E46 3-Series brake upgrade. Despite the use of the smaller components, the brakes performed flawlessly during the much longer 25-hour enduro event. According to Steve Ruiz, StopTech engineering manager, “this successful result once again shows the benefits of the StopTech AeroRotor® and AeroHat™ design in racing applications.”

2 different functions... tho Im not sure what the function of drilled is other than appearance; slotted routes hot gases from under the pad to let it clamp down. I think drilled is sposed to be for cooling and less weight; but rotors absorb heat into their weight; less wouldnt be real good for fade.
now J Ritt can come along and correct all of that information with he truth

Mr. J Ritt
Your information has sold me. Any additional thoughts of a Four wheel 335mm brake combo for the 350Z?
I'll keep in touch with Jeff@performance ..
Good show
Cheers Amy

BTW, for all of the people who actually cross-drill their rotors after the fact instead of buying rotors with holes made as a part of the casting process, the cracks in the StopTech rotor are nothing compared to what ghetto-*** cross-drilled rotors would look like after a few sessions on the track.

Congrats! Quick question, I noticed you have slotted rotors on there instead of drilled, why? Are they better I was always under the impression that drilled was better.

Slotted rotors scrape the pads clean of deposition as they pass over and slighty fall into the slots. Drilled rotors are for ballers and stockcar drivers from the '50s. Rotors were first drilled in the early days of motor racing because the brake pad compounds of the day would outgas and create a thin layer of gas between the pad and rotor which had the same effect as a puck on an air-hockey table. The rotors were drilled to allow the outgassing to dissipate and not remain trapped between the pad and rotor surface.
