Tilton Engineering invented the carbon/carbon racing clutch and patented the drive system in the 1980s. It was the first carbon/carbon clutch ever to win a Formula One Grand Prix (Ayrton Senna’s Lotus-Honda at the 1980 US Grand Prix in Detroit)

Tilton’s 7.25″ OT-II carbon racing clutches offer a unique combination of low inertia, high torque capacity, high heat capacity and smooth engagement characteristics. The carbon matrix plates (driven and floater) do not warp from heat, providing consistent shifting and minimizing heat-related clutch failures. The smooth engagement characteristics of the carbon plates provide excellent drivability and reduce shifting shock to other driveline components. Through the use of additional pressure plates (shims) and periodic rebuilds, 7.25″ OT-II carbon racing clutches offer a long-life option for the serious racer. 

    Proudly Made In The USA.

      Who We Are.

      In 2019, FISCH RACING TECH emerged from the collaboration of Henry and Sigi. Henry paired over two decades of experience as a machinist with Sigi's 15+ years of expertise as a mechanical engineer. Recognizing the demand for high-quality transmission adapters and racing components within the enthusiast community, they embarked on the creation of the renowned Fisch Racing Tech Adapter System. They started product development in 2019 and successfully introduced their first products to the market in 2020.

      Don't take our word for it!


      Which clutch should I run?

      For Mostly Street Use try to keep a “single” sprung hub so that engagement is less jarring, but if you need the extra rotating mass and don’t mind a really aggressive pedal you can go unsprung.

      We recommend the ACT that is on our website for 580 ft lbs (600hp) ACT NZ2-HDG6 (6 puck, sprung hub, HD pressure plate; ACT NZ2-HDG6). If you are going to be upgrading your engine soon, ACT pressure plates and clutch discs are interchangeable so you can upgrade just the disc and get an extra 150 ft lbs out of your clutch for only a couple hundred dollars.

      Another cheaper option is the McLeod:

      For Mostly Track Use try to go with “multi” 7.25” Tilton 2-plate cerametallic or 3-plate metallic. Cerametallic wears a bit slower, but weighs a bit more than metallic. Metallic sounds more broken. Lots of good racecar noises. This is a good thing. Cerametallic doesn’t offer 3 disc, so a good feeling pressure plate caps around 760 ft lbs.

      Tilton 2-3 discs can be built to hold over 1300 ft lbs. More than the trans is likely going to be able to handle…. So power isnt the cap for these clutches

      Pros: Very lightweight. Engine revs out quickly. Race Car sounds. Replacement disc packs are cheap.

      Cons: Unsprung hubs = harsh engagement. RPM need to be high in order to slip it at all. Loading your trailer, or sitting in traffic will not be fun

      For Mostly Street and Track with higher hp you can use the Tilton ST-246 (9.6”). ST-246 clutches are designed to provide high torque capacity, low wear rate, smooth shifting and good drivability. All ST-246 twin disc clutch kits are available with either sprung-hub organic discs (850 lb-ft capacity) or solid-hub cerametallic discs (1250 lb-ft capacity). Right now only available for the JZ adapter kit.

      Is the clutch included in the kit?

      No. You have to buy the clutch separately, but you get 100USD Off when you buy as package. See clutches:

      Which clutch master should I use?

      For most standard clutch pedal ratios, the hydraulic release bearing (HRB) will work best with a 3/4"bore master cylinder. For the ST-246 clutch you should go with a 7/8” bore master.

      Can I run a different clutch than you recommend?

      The single option will work with any good quality 350Z/370Z/G35/G37 clutches. PLEASE CHECK BEARING CLEARANCE AFTER INSTALLING! Stack height are different.

      For multi option we use a ‘step type” flywheel. Be sure that the one you have selected is meant for a step type mount.

      Do you guys sell driveshafts?

      Not at the moment. We have only Yokes:

      You will need to have a driveshaft made, or your OEM one modified, when putting a CD into a car that didn't come with one.

      1350 series joint is about 37.5-percent stronger than the 1310 series

      There are so many factors that play into how much power a U joint can handle. Tire size, vehicle weight, gear ratio. Ask your driveshaft shop what size they recommend for your application.

      Where can I get replacement parts?

      On our website you find a lot replacement parts:
