Product Description

THIS KIT IS FOR USE WITH STOCK FLYWHEELS, ONLY.

SPEC has developed a new line of clutches for the 2012-2017 Chevy Sonic aimed at performance, but without the compromises often associated with a performance clutch. SPEC clutch offer a total of 5 stages for the Sonic, however we’ve decided to concentrate on the first three because of their super friendly street manners and the ability to hold up to 375trq.   If you need more than that let us know and we can price out the other options for you.

We currently have the Stg 2 Kevlar clutch in our Sonic and absolutely love it!  The vague feel of the stock clutch is completely gone.  The high clamp load pressure plate does add some additional effort to the pedal, but it’s more along the lines of what you’d expect from a factory performance vehicle.  The Kevlar disc we opted for gives a positive bite without being grabby, doesn’t chatter and engages as smoothly as stock.

 If you are interested in a kit containing  an option for a performance oriented lightweight flywheel, please see our other Spec Clutch listing.
