Dear Mr. Dendyuk,
Thank you very much for contacting EXEDY Clutch Europe Limited and for your interest in the EXEDY Racing Clutch range.
I have already made a preliminary reply to Mr. Enache at Racing Nick, so he will reply to you shortly.
ZK07H is actually an EXEDY Uprated Sports Organic Kit ZC15T Cover and ZD15H Disc
ZK07T is actually an EXEDY Uprated "S" Type Metal paddle type Kit ZC15T Cover and ZD15T Disc
For the Bearing, BRG871 which you have on the Kit number we are not sure if that is correct? Is it a Concentric Slave Cylinder design.
At the moment EXEDY does not offer a lightened Racing Flywheel for this vehicle application .
So, the above are EXEDY Single Series Racing Clutches, not standard OEM Kits.
Thus, we will continue our investigations and reply back to Racing Nick who will in turn reply back to you.
Yours sincerely,
Richard Ford
