Hmmm last time I ordered a SB kevlar clutch for another customer, they shipped the next day... Are you waiting on Toyota parts then?

Oh, btw I found a picture for you that shows that the TRD Twin comes with its own flywheel (referring to your question earlier in this thread):

I just wanted any advise on what is the best performance clutch to get, i have been looking at the TRD Twin plate sprung cerametallic clutch kit, complete with lightweight flywheel - up to 750NM /800PS, but just wonder from anyones experience whether they could suggest any other good alternatives.

Any help would be appreciated (i hate to see it just sitting on the driveway)

Cheers

I have a HKS stage 2 clutch that would make a perfect fit for your situation. And it's for sale! It only has about 4k miles on it, and there is absolutely nothing wrong with it. Please email me with any questions at dixonm@uwstout.edu I am very serious about selling this so please feel free to contact me with any questions that you have no matter how minimal they may seem.
Thanks,

Mike

Hey,

I have installed the clutch and flywheel, that you have reccommended and have found that the gears are very stiff now, and the clutch is very high, i.e. it is very jerky when i drive it.... is this normal, until i break it in. The garage advised me that there is around 8mm of play in total between the fork, Slave and Master cylinder, would this have anything to do with it.

Also they were saying that the Standard Flywheel was completely flat but this lightened one concaved in on one side, would this also make a difference??

cheers

That doesn't sound right. Are you sure the clutch pedal is adjusted properly?

Yes. That play should not be present IF the clutch was properly installed & adjusted. Who did you take it to?

What "Standard Flywheel" were they referring to? The South Bend Kevlar clutch doesn't come with its own flywheel, and a brand-new oem flywheel should be perfectly flat. If you installed a flywheel that is not flat, then yes, that could also make a difference.

They said they had to adjust it slightly. I took it to a local garage. No i bought the 'RPS Cyn-R-G Segmented Flywheel for 1993-98 Supra TT, the one you suggested, and since this is specifically designed to fit the Supra TT, i don't really see why there should be a problem. The flywheel they were talking about was the orginal "stock" one.

Would you recommend that i change the fork 1st and see how it is, and then perhaps the Slave and Master if need be.

cheers

I see. Unfortunately ime most "local garage"s (including 'yota dealerships) don't have the experience necessary to work on a 400whp+ gt sportscar. Fwiw, in the future, I'd strongly advise you to to take your Supra to a shop experienced with Supras if at all possible. Improper installation could easily explain why your gears are stiff.

Which Ashford do you live in? CT? WV? AL? If you're interested, I may be able to recommend an experienced supra mechanic or owener(s) that you can get in touch with.

Honestly no. At this point, I'd recommend you have it checked out by a shop that is familiar with this car. For example (hypothetically speaking), if your Supra shifted properly before you took it to this "local garage", why would you suddenly have to change the clutch fork or slave cylinder? Did your "local garage" break these parts?

If you have the TSRM, you could try adjusting the clutch pedal yourself. It's pretty easy mechanically speaking. It can be done with one 12mm wrench...but you need the TSRM to make sure you do it right, since adjusted wrongly it can cause your throwout bearing to wear out very quickly. When properly installed & adjusted, there should be absolutely zero "play in total between the fork, Slave and Master cylinder". When properly installed & adjusted, the engagement/disengagement point should not be "very high".

P.S. Your earlier post said that the lightnened flywheel is "concaved in on one side". Again, this could possibly be a problem, depending on which "side" they're talking about. Imo, if the shop suspected there was a problem, they shouldn't have installed the flywheel.

Hey,

I spoke to Dusty at MVP Motorspoorts last night, who was very helpful. He advised that when you change/ upgrade your clutch, they can simetimes become stiffer, however that there should not be any sort of play with regards to the fork etc. He said at 1st try putting it into 2nd then 1st and this should make 1st gear easier to go into and the same applies for reverse.

Also he was saying the generally Spring plated clutches are installed in a different way to the stock clutch, i.e. the opposite direction to which a stock plate would be fitted. But said that's how RPS clutches are fitted, but that they don't really deal with Southbend clutches, so that may not be correct for them, but generally they do fit in the opposite direction........Do you know if this is true or not???

Yeah if i had a choice i would of taken it to a Supra garage, or at least a garage with some sort of experinence in performance cars, but i was limited in choice, and most specialists are too far away, especially with me having to tow the car to them!

I actaully live in Ashford in Middlesex in the UK, im sure if i was in the US i would of found loads of specialist garages..... Dam the UK.. ha ha!

Cheers

Yes, it's true. You should install the clutch exactly as specified by the manufacturer (SouthBend).

Great how would go about getting touch with him, is he on this forum, if so maybe i can chat to him 1st to see where abouts in London he is.

Yeah i think i'll call southbend back again as the 1st time the guy was not very helpful, saying that its fits the same way as all other clutches.... i reckon he just couldn't be bothered to explain. The reason we don't know if it is installed properley is beacause no instalment instuctions were provided with the package when delivered!
