G'Day Pusches
In the meantime I also did some searching on the internet on DE sites. I have found one who provide an uprated clutch for Ci and CSi models. Web link is :
www.g-power.de/
G330090020
G-POWER clutch set GP R - E31 850i/850Ci/850Csi amplified Consisting of pressure plate (with changed pressure features), amplified racing clutch disc and corresp. bearings, e.g. for EVO II kits.
(Assembly-time ~ 5 hours)
In fact they have quite a lot of stuff for the 8-series
Cost for the CSi was approx 1500€ including VAT. Since standard one is £480 including VAT, the price difference is not too much
Thanks again for your help
