Need help from france!

Hello everyone, let me introduce myself. I'm Benoit (Ben), I'm 42 years old and I'm French. Nobody is perfect! Excuse me for my average American. I own a 550 maranello and a mondial 3.2. Recently the clutch of the 550 (the thrust bearing) dropped. I have to replace everything. I've seen OS Giken clutches, which are more race oriented. This is perfect since I would like to do track day. Do some of you know this brand and have an opinion about it...I'll take any advice for the track day.
Thank you in advance and good morning to all!
