Just wondering what everyone's thoughts were on this clutch. I would like to be able to get a lightened flywheel with it. I'm a little less than BPU so would this clutch not be the right one for me? THanks,
Zach

I have had an RPS stage 3 with lightened and it seized up on me after 45 passes on it. But the clutch's main purpose is for agressive street driving. When I pulled the clutch out there was plenty of pad material left. So in fact it would have lasted for a long time on the street. Another thing is that the lightened flywheel chatters quite a good bit. I am currently using a Arizona clutch (factory flywheel, Airzona disk,RPS pressure plate). The clutch feels stiffer than stock and there is no chatter from the factory flywheel. I ran a best of a [email protected] on the RPS and the Arizona posted and [email protected], which shows the RPS was slipping. The 60' time on the RPS was 1.836 and the Arizona 1.799. The arizona with flywheel will run about 1300 and the RPS is the same price.

I recently had the Arizona clutch fitted and I have to agree with Brian that it is a much nicer clutch. It is still brand new but it already drives like the RPS clutch did after 1000 miles. The RPS clutch when new is almost impossible to drive.

I had the RPS Stage 3 sprung hub with lightened flywheel but one of the springs in the clutch came loose and wreaked havoc on the flywheel etc. I still don't know what the cause was but I am not going to try another RPS clutch again.

Based on the recommendation of some very high horsepower Supra owners I decided to go for the Arizona clutch.

Wow. Thanks for the information guys. i was just about ready to purchase the RPS sprung clutch also with a mueller lightened flywheel. With the Arizona clutch should I just get the stock supra flywheel to go with it then or can a lightened flywheel still work well with it. Thanks,
Zach

Stock flywheel. The AZ Clutch isn't sprung so, if you wanna show your tranny some sympathy, stick with the stock flywheel :D
Ok good. just checking. :D

I just bought an RPS Stage 3 sprung hub clutch and a stock flywheel from Dusty last night. It goes in on Wednesday, so I'll let you know how I like it. (Rob Smith recommended the sprung stock flywheel with sprung clutch setup for the best streetability.)

FYI I did drive a single turbo Supra with a Mueller flywheel and RPS Stage 3 sprung hub clutch last night (Qualen's). Engagement felt worse than my TRD Twin in terms of engagement chatter, and it engaged over a wider motion of the clutch pedal (I'd say maybe 3 inches of motion versus 2, but that's just a guess). I'm guessing that the increased chatter is just due to the fact that it was just installed (10 miles on it) and not broken in yet.. everybody says they get smoother as they break in.

I will miss the TRD Twin's light pedal though. The RPS single-disc pressure plate is considerably stiffer. But I guess that's the price I have to pay for a quiet car at idle. That and the horsepower I'll lose through the stock flywheel..

Thanks for the information Andi. Let me know how it works out for you. That race course looks really fun. I wish we had something like that here.

I also ordered the RPS Sprung Stage III from Dusty a few days ago. I will be using it with a Mueller Lightened Flywheel. I have heard that this setup is very street drivable, chatters very little, and apparently the difference with using a lightened flywheel is incredible....

I guess we will see, it should be going on sometime next week. I will post feedback. currently I have a stock flywheel and the RPS Turbo Clutch... not a good setup for BPU

Regards,

Bartel

I've had more problems w/ RPS clutches than I care to recall. However, Rob has always stood behind the product and his customer service was excellent. BUT that still doesn't give me back all my money for labor (rob did reimburse one labor fee) or the down time on my car. The last (and current) clutch I have is the RPS w/ the full metal race disk. I love this clutch....it has been the best by far and is actually very streetable after about 1k miles of break-in (pretty harsh for the first 500 miles or so). I also use the stock flywheel.....for drag racing purposes it is much better than a light flywheel. If I were going to buy a new clutch it would probably be either the AZ clutch or the HKS triple.

... chatters very little... Dream on. When I had this combo and I stopped at a traffic light people were always looking at my car because of the chatter. The Arizona clutch is way more civilised than the RPS Stage 3 and as I've said before when new it is already more driveable than a broken in RPS.

here is what Dusty from MVP has to say about the AZ clutch
"
The AZ clutch is kind of new and has not been tested much but from what I can tell it works well. It was developed for heavy track use and is not quite as friendly as, say, the RPS stage 2 but is very equal in drivability to the RPS stage "

guess I am going with either RPS2 or 3 clutch set...not sure about flywheel choices yet.

I have an RPS stage 3 with a stock flywheel. It chatters pretty bad at idle WHEN HOT...

When cold, no problems.. and only when really hot, like after a quarter blast or some hard driving.. during normal cruising, street driving, doesnt seem to be a problem.

If i push on the clutch, it goes away completely, regardless of temperature tho...
