As far as we can tell, this vehicle doesn't have one.

On newer BMWs it's integrated into the slave cylinder. I know Toyota tells us it's all different but I can pretty much guarantee it's the same. The Z4 uses the same slave cylinder part number.

You can either manually remove it or swap with an older E9x slave.

Would that also make the travel a bit shorter? I feel like I'm almost having to step on the road just to shift.

Also, would you know if there are any BMW clutches that could theoretically fit the supra? My buddy is putting down 610 Ft-lbs on his supra and the oem clutch is not liking it when he goes to the drag strip.

Nope, but a clutch stop is cheap and easy to install. I have one in mine with all the washers. No gear lockouts, no issues.

I bought from the seller on eBay because I heard he was the original, but since it's cheap a lot of other companies copied the design.

Edit: Jury is still out on oem upgrades. The M3/M4 clutch would probably fit because, from what I see, the supra clutch is a twin disc and the F8X/G8X are the only other cars that came with one. But their limits are around 600 ft lbs as well.

So an interesting situation I found myself in today... I dropped my car off for some warranty items (new speakers, replace harness bar rattle, chassis malfunction) and to inform them of an issue I experienced. So about 2 months ago while accelerating from 2nd and then shifting into 3rd I experienced a total "lack of clutch" It slipped completely from about 3k to redline, at first I did not even realize what was happenings as it wasn't just a little slip and it caught, nope acted as if it had no clutch left at all, I let off, and accelerated again completely fine through all the gears, (albeit a very strong smell of burnt clutch for 3-4 hours) It was weird and unsettling but I chalked it up to fluke.( I did mention it to the dealer while getting the first service and they noted it) Driving again the other night under very similar conditions the exact same thing happened under the exact same circumstance, accelerating and 2 to 3 shift. And the same hours of smell, I was with a passenger this time and we both came to the conclusion that this isn't just a fluke and the car acted as if it had no clutch at all, but then when doing the exact same thing 3-4 more times it would not slip again. Obviously there is an issue, heat damage somehow maybe? ( I actually broke the clutch in pretty strictly for the first 500 miles) Slave cylinder? Pivot pin? few different things it could be. All of this is fine and dandy as it is a brand new car with 3k miles and under full warranty, so no reason to worry as I have not done a single power mod, no tuning etc. Well today after dropping it off I got a call from my tech saying he reached out regarding the issue to their FST and other appropriate channels. I am told that the clutch is a wear item and is only under warranty for the first year /12k miles, great im at 3xxx and have had the car for less then 6 months! Nope, not that simple. They will look at it but only if I agree to pay a tear down fee, if something is found they will cover it and fix it, but if not I am stuck with the whole labor bill for them checking... So they won't even check till I pay thousands out of pocket and risk not getting it back if they "deem" there are no issues which I know there clearly is but not sure what it will take to find it! so it is definitely precarious I find myself in. The tech said he will call the Field service tech to come down locally and have me try and replicate the issue in front of him in hopes he waives the tear down fee bs. I have been absolutely loving my MT, truly an amazing platform but this really is not what I wanted to hear... for 3k miles and being at a stock power level... slipping is pretty unacceptable. Just a little "rant" and update on my A91 MT!

Mine is 11,200 mile and the clutch said bye bye!!!????

How much power were you pushing and how hard were you driving the car?

I would also like to know this.

Hopefully this isn't a long lead time item and repair.

Wow that is not good… a full failure is definitely a worrying sign for me and other owners, the clutch is under warranty for 1 year/12k miles so hopefully they don’t give you any issue…

Update @NitroYellowMKV ?

 

[DGINR8supra]

Following this and lead time for clutch components

If I were you I would be calling corporate Toyota of North America and raising hell.

If I were to have chosen a 6MT, it would be for the sole purpose of kicking the dog shit out of the clutch and sliding frequently. This is really a shame, I hope these instances are isolated.

A manual Supra is “isolated” with the small amount manufactured so far. That makes it seem very common with the small quantity of owners here already experiencing issues in some form or another. Very concerning in my opinion.

Great!!!

After all this time waiting patiently and finally owning it, never thought that the clutch was going to be a problem.

Im having dejavu now. I’m feeling like the time I owned an Evo X MR.

I called everywhere to find it and end up trading it in because the DCT won’t hold up after a small turbo upgrade.
