Based on advice from Jimmysidecarr, I decided to post the following as a new thread. I hope it's helpful:
Hello everyone. I just wanted to give some info regarding the McLeod RST. I recently had my shop install a Spec 3/new Fidanza friction plate and I personally hated it due to the chatter/shudder getting into 1st gear -chattered like hell in the trans area and sounded like wheel hop in the rear-, although I was told this is normal during break-in.
It did get a lot better around 1000 miles -not completely gone though- but I jumped the gun around the 400 mile mark and ordered the McLeod RST/FRPP TOB/Lethal Sleeve/Clutch Fork/ and replaced the center plate in the Fidanza aluminum flywheel for a second time as I wanted to be sure everything was new and there were no weak spots in the setup.
Anyway, the RST does have an incredibly light pedal feel, (I swear it is softer than my wife's Scion! It's funny to jump into her car and think that her clutch is harder than mine since it was the extreme opposite for the past few years! It is absolutely, 100% as soft as everyone claims)
It does still have a slight chatter/shudder getting into 1st & reverse, but it is a fraction of what the Spec's chatter was at the same point-in-time during break-in. Now, I'm only at about 300 miles into break-in with the RST so this may be premature as it may completely disappear very soon, but from what other posts I've read and what my tuner explained (they have installed dozens of McCleod twin disc clutches on many high performance cars) this too is normal and expected from even the McCleod RST twin disc, but should completely disappear with time. Just keep in mind the chatter/shudder from the very beginning was substantially less than what I experienced with the Spec 3, but it does still exist with the RST.
Personally, I do not drag or abuse my car, and driveability is of utmost priority which is why I replaced the Spec with the RST, but to be honest, I was and still am somewhat disappointed that there has been even an ounce of shudder with this expensive, and arguably the best, clutch setup on the market. Other than getting into first/reverse, the clutch shifts, feels, and performs perfectly although as I said, I'm still in the break-in period.
Maybe someone out there can explain to me why even the organic twin disc chatters/shudders when I thought this upgraded clutch would not have such an issue from the start.
Can anyone confirm that even a 'softer' organic material twin clutch can/will chatter during break-in? It seems the more I search for RST posts, the more I find that chatter is fairly common during break-in.
Could it be because I have an aluminum flywheel vs. steel flywheel?? Anyway, I do enjoy the clutch and pedal effort but I simply hate the slight chatter from a start. This setup costs way too much to put up with this, although this issue may be a distant memory in a couple weeks. I hope it goes away soon! I'll keep everyone posted. Thanks.
