Coordsport sell an output gear set 4.875 ratio for about £260. Was available in the RS 5 but was dropped for the 6. Your car comes off the line like a rocket but you need second gear instantly. Nice on a very tight road. Don’t even think about this with the stock clutch!
I have fitted a Ralliart three paddle ceramic disk with their cover. I have been very happy with this clutch. It is quite drivable and holds well. However I am starting to believe that if I ask much more of it the answer will be no! A friend of mine who has implemented an anti-lag system tells me that a very robust clutch is necessary. I intend to go the same rout with anti-lag and launch control.
Please tell more about the OG Giken clutch. I’m interested.
