Hawks Motorsports’ Announces Sinister 1.5 To Their Line of Clutches

If you’re an avid F-body fan like we are, the name Hawks Motorsports probably rings a bell somewhere. It should, as they’ve been at the forefront of restoration and performance products for 3rd- and 4th-gen Camaros and Firebirds for roughly two decades. In addition, they provide in-house modifications, dyno-tuning, as well as custom fabrication — to ensure that your car will stand out from the thousands of copies out there.

Over the last several years, they have expanded into both older, and newer performance cars; including 5th- and 6th-gen Camaro, C4+ Corvette, Pontiac G8 and GTO, and CTS-V.

So, in addition to offering restoration and lightly used OEM products for our favorite pony cars, they have stepped up to provide us with performance products under their sub-brand, Sinister — which includes a line of clutches.

Official Release:

Introducing Hawks new addition to our Sinister Clutch Line!

Hawks Sinister Stage 1.5 Clutch Kit with Billet Flywheel; Camaro/Firebird/GTO/Corvette/CTS-V 97-2014 LS1, LS2, LS3, LS6

The Sinister Stage 1.5 clutch package includes everything you need to upgrade your LS clutch package with an easy pedal effort, effective holding system that handles up to 600 RWHP cars up to 4200lbs. Sinister Stage 1.5 Clutch set is for heavier bolt ons; HCI etc. System includes a high clamp 2800 pound pressure plate that maintains a light pedal effort and provides maximum surface area for heat dissipation without distortion or warpage.

The clutch disc features premium full face organic friction material on the flywheel side and is full face metallic on the pressure plate side. This not only suppresses transmission noise and gives additional strength over stock hub configurations while allowing more power and abuse of heavier cars like the 5th-gen Camaro.

Rounding out the system is a billet steel flywheel that is precision balanced and surface ground to insure minimal run-out and optimum mating surface for the clutch disc to seat against. This clutch is great for 5th gen Camaros, 04-07 CTSV’s, Pontiac G8’s, 04-06 GTO’s. Works especially well in lighter weight applications also.
