tbourner Posted July 4, 2005 Share Posted July 4, 2005 I know nothing about clutches, but am still looking into getting a new one cos mine's getting worse. But what do they all mean? RPS street/sport 6-puck sprung/solid hub? And do I NEED to change the flywheel when I replace the clutch - if it hasn't actually gone wrong in any major way? And is it worth getting a better flywheel anyway? And will the new clutch be a PITA for daily driving? Like noisy as I've read in a few posts?

Homer Posted July 5, 2005 Share Posted July 5, 2005 I had exactly the same dilemma a couple of months back - Dude & Terry S gave some great advice. Here’s what I managed to learn (hope I understood it correctly!): - You only need to replace the flywheel if it’s knackered, so not necessarily required when a clutch is replaced. - Noise & rattles are caused by lightened flywheels, the clutch and pressure plate make no difference to the noise level - I asked for a clutch that was fairly close to stock engagement but could handle ‘small single’ torque - not had it fitted yet but it’s apparently only slightly heavier than stock and has a smooth feel - last thing I wanted was an on/off clutch. Terry S seems to have done some serious homework on clutches so best bet is to give him a call to discuss you needs Link to comment Share on other sites More sharing options...
Suprasteve Posted July 5, 2005 Share Posted July 5, 2005 me too, i think mines going. What sort of costs are you looking to have it supplied and fitted ? Link to comment Share on other sites More sharing options...
Homer Posted July 5, 2005 Share Posted July 5, 2005 Steve, the kit I got will be £450+ for the parts, with a minimum of £100 fitting. Not sure of the cost if a flywheel replacement though... Link to comment Share on other sites More sharing options...

Not sure of the cost if a flywheel replacement though... thats not too bad, for some reason i was expecting #700+ Also you get a better than stock one so at least you're getting something better with your money. Thats the way i prefer to look at it rather than spending all that money and get nothing out of it...you know what i mean Link to comment Share on other sites More sharing options...
Fox Posted July 5, 2005 Share Posted July 5, 2005 If your not in a hurry!! My Supra has had the clutch changed to a RPS Street Max and i also changed the fly wheel to the RPS Cyn-R-G Flywheel!! However i won't know what it's like to i collect the car tomorrow!!! But to be sure i'll let you know!!!! ROLL ON TOMORROW Link to comment Share on other sites More sharing options...
Homer Posted July 5, 2005 Share Posted July 5, 2005 That’s true, but also think of the longevity. The stock clutch and plate will last for 70k+ if treated well, most of the people I know who have the aftermarket clutches tend to muller then in a MUCH shorter time. I know a couple of people who've been through the RPS clutch in 10k miles. From what I've found, if you want value for money then stock will be best Link to comment Share on other sites More sharing options...

tbourner Posted July 5, 2005 Author Share Posted July 5, 2005 Can get a 6-puck sprung hub RPS sport from Dusty for just over £400 delivered. He keeps saying I HAVE to change the flywheel though, and that you absolutely cannot SAFELY reuse the stock flywheel - have to replace with a new stock one or an uprated one.

Fox Posted July 5, 2005 Share Posted July 5, 2005 I will take me 3 months to do 1000 miles I was told not to go hard in her and let everything bed in, for a few hundred but nothing like this...... DAM Looks like i'll be going for an around ireland trip this summer!! P.S Thanks for the heads up!! Link to comment Share on other sites More sharing options...
tbourner Posted July 5, 2005 Author Share Posted July 5, 2005 Advice I was given: 1,000 mile break-in. First 500 miles no boost, 4,000 RPM’s and below, no launches or hard drops. Next 500 miles work up to full boost, work up to full RPM’s, no launches or hard drops. That was for the RPS sport - dunno about others. Link to comment Share on other sites More sharing options...
Fox Posted July 5, 2005 Share Posted July 5, 2005 it will be very hard not to tramp on the loud peddle for 1000 miles!! awell if it has to be done!! Link to comment Share on other sites More sharing options...
SimonB Posted July 5, 2005 Share Posted July 5, 2005 RPS only guarantee their clutches if you change the flywheel (or at least have it refaced) at the same time. You're looking at £200 labour probably to change it, you may find your existing flywheel is fine when you get it out, or it may be knackered. I reckon if it's done a good few miles you're better off changing it at the same time. Basically if you change to a lightweight fly you should go for a sprung hub clutch plate. If you stick with the standard fly you want an unsprung hub clutch plate. I have a RPS flywheel, and while it does improve the throttle response you will have to put up with the gearbox sounding like it's broken. It will rattle at idle and make a graunching noise when pulling at low revs. I'm going to change back to a stock one when my clutch needs changing again. I have a South Bend full kevlar clutch, which is very good. It feels almost the same as stock, with a slightly narrower bite point. It's a 6 puck, as most of the aftermarket ones are which means you sometimes get a judder as it engages as some of the individual pucks grip before the others. It's done probably 20k miles including a couple of trackdays so far and is going strong. The RPS ones have a slightly heavier pedal feel I think.

Ian C Posted July 5, 2005 Share Posted July 5, 2005 An RPS Street Max is a stock friction plate with a beefier sprung cover. It requires no bedding in, but it merrily holds 500+bhpish Stiffer pedal for sure, as my left leg will attest to (I do find myself trying to push 'normal' clutch pedals through the floor now). Drives like stock otherwise. Can't see it dying by 10,000 miles seeing as it's stock and my original stock one lasted 30k in my ownership, up to 18k before that as well. 400+bhp hybrids setup too. But the I'm easy on the clutch... -Ian Link to comment Share on other sites More sharing options...
tbourner Posted July 5, 2005 Author Share Posted July 5, 2005 What's the difference between the RPS street and RPS sport then? Link to comment Share on other sites More sharing options...
Guest Terry S Posted July 6, 2005 Share Posted July 6, 2005 If you must use the RPS get the street clutch as it uses a stock disc, so the engagement is good.. There are other altenatives with less required pedal pressure, but TBH for 90% of you I would say go back to a stock clutch, you'd be surprised what they can hold. After that, The Kevlar discs are cool. Link to comment Share on other sites More sharing options...
tbourner Posted July 6, 2005 Author Share Posted July 6, 2005 Isn't a standard clutch the same price as an uprated one though (well £50 maybe)? What's the point in that!! I need to drive someone's that's got an RPS sport with flywheel really! If I'm going to be changing my clutch and flywheel to a new standard set I might as well upgrade! It can't be that bad to drive!! Link to comment Share on other sites More sharing options...
Guest Terry S Posted July 6, 2005 Share Posted July 6, 2005 probably, but drivability is great. Be careful with paddle clutches, they are very grabby Link to comment Share on other sites More sharing options...
tbourner Posted July 6, 2005 Author Share Posted July 6, 2005 So the RPS sport with street disc and a standard flywheel is a better idea - I'm not exactly Mr Big Power at the moment lets face it!! But I might be one day. Link to comment Share on other sites More sharing options...
Fox Posted July 6, 2005 Share Posted July 6, 2005 I LOVE MY SUPRA!!!! got the car back tonight and the clutch feels great!! The fly wheel realy does make a big diff to the way the car rev's out.... The peddle takes a little more push but it's just right and the car has a nice bite and short pull.... have'nt give her some yet but i'll let ya know what it's up to!!

tbourner Posted July 7, 2005 Author Share Posted July 7, 2005 Is the flywheel really that noisy? That is my ONLY concern with getting a lightweight, I don't really care about small biting points and heavy clutches (you may say I will care after a few thousand miles - but I really don't think I will). So if it's not very noisy then I'll go with that!! Link to comment Share on other sites More sharing options...
Fox Posted July 7, 2005 Share Posted July 7, 2005 Not that i can tell mate, the car idles fine with no clunking or ratteling at the min, but thats not to say in a week or so that might change. The car feels way more responcive and i would recomend this setup to anyone!! Im defo well please and i think it's money well spent. Link to comment Share on other sites More sharing options...

SimonB Posted July 7, 2005 Share Posted July 7, 2005 As Terry says, when it gets hot it rattles a lot more. After a few hours drive through France when it was 35C mine was shockingly loud when I stopped for fuel. The rattle on idle I don't find as annoying as the graunching you get at low revs (e.g. when pulling from Although it does rev more freely, it's not a huge difference, because the pressure plate is pretty heavy anyway, so just making the flyweheel lighter doesn't make as big a difference to the overall weight as you might think.
