Our now-turbocharged "Budget NC" had a clutch failure at Circuit of the Americas which then destroyed our 6 speed, so we finished the event on a backup junkyard 5 speed with the boost turned down.

That 6 speed has just come back from a rebuild at Walter Motorsports, and with perfect timing OS Giken has sent us this hot new Twin Plate Clutch and flywheel assembly for the NC 6 speed to try out.

First test driving of new twin disc today, and it's awesome!

I was dreading the first drive, we wanted the reliability on track days of a clutch like this which can handle easily any boost we dial the turbo up to, but I was not looking forward to the typical twin disc rattle. Fortunately, zero issues.

Pedal pressure is better than our typical ACT, pedal travel is better too (very much similar to stock release feel and just slightly more firm). No issues on first drive, color me impressed. My prior experience with typical twin disc was a lot of rattle potential, with this unit I hear a very soft constant metallic ring sound at a stop light with the clutch fully depressed but otherwise nothing and if the radio is on even a little then I can't hear it at the stoplight. Smooth action, good feel, happy first day! Hopefully a track day soon after we get the new built trans some break in miles.

Great to hear... waiting on Walter motorsports to confirm the ship to address for my core but I will be evaluating my ACT clutch after one race season of boost in the next week or so... I don't expect to need a replacement just yet but I assume this fancy twin disk option is a season or two away... excited to hear more!

Hi guys,

Any updates on the new twin disc clutch? Track days?

Also, is there an oil cooler kit in the works?

I need both of these items!

Thanks!

Twin disc is working great, on the site and customers have them installed.

Oil cooler still in development, no ETA on when that will finish, it is one of those things that is done when done and not done until it is done.
