Tetra Disc Clutch Kit for Porsche 991 GT3 Cup | With FlyWheel Kit

Tetra Disc Clutck Kit for Porsche 997 GT3 Cup | With FlyWheel Kit

The Kit includes

• 140 mm Tetra Disc Clutch Kit 

COMPONENT FEATURES:

The flywheel is made of forged CrMo steel and special heat treatment (Nitriding), offering a surface hardness of 60 HRC which is twice the HRC value of those flywheels with a polished/machined appearance and that is why they wear very quickly, especially in high compression engines.

The higher the HRC value, the more resistant the flywheel is and therefore the longer the service life and reliability;

The clutch press is made from forged 6061T6 aluminium and treated with hard anodising. We add steel rivets to the legs, for almost lifetime durability.

The top/pressure plate is made from forged chromoly steel for superior performance and durability.

The clutch disc is made from sintered material and various designs are available, although the standard version has 3 large pads, as shown in the pictures. Splines other than the original are available on request.

We include a 100% metal clutch support and clutch collar, especially for racing clutches, which replaces the unreliable original clutch collars.

Plug & Play solution with no modifications required.

MAIN BENEFITS:

Very significant lightening of the flywheel + clutch assembly with respect to the original, thus reducing rotational masses resulting in greater acceleration and more immediate engine response.

Improved shifting at high rpm.

Very long life of the friction elements and low cost of these.
