They are all billet unlike the RPS twin and have different options. Their full carbon costs more than the Tilton's carbon and has a lot more surface area than the Tilton. This is definitely the company I will be purchasing my clutch from.
Well woke up this morning and saw my ATS cltuch on the table!!! It comes with everything you will need. The kit to covert the pull to push type. All the bolts and springs are in the kit. I will try to post pics soon.
