Before u spend £300 check everything else. My thrust bearing collapsed and it gives all the simptons your getting. Doubt thats the problem, but you should check that the clutch is pushing out the slave cylinder piston enough to push the clutch arm thing enough to release the clutch if thats makes sense. When u push in the clutch the arm on the gearbox moves abit over 10mm on mine although u could measure yours and someone elses to compare. Its free to check that before you spend £300.

Also in america when the clutch cylinder starts to wear out instead of buying a new one they buy a longer piston for the cylinder on the gearbox, it costs $15 and fixes the problem for another 50k miles

To sum that all up get a measuring tape and measure how far the arm on the front of your gearbox moves when an assistant presses your clutch pedal to the floor. Then measure on someone elses GT to compare.

The americans also use that $15 part I mentioned when they fit a heavy heavy clutch, sounds like your thing too. I'll find the link.

This items falls under the classification of “dirty little problem solver”.

Many people have found that aftermarket clutches, especially those with heavy pressure plates, make complete disengagement of the clutch difficult.

This makes gear changes difficult and may make the transmission grind when shifting from neutral. This clutch slave cylinder push rod is ¼” longer than stock and is made from CNC turned 303 stainless steel.

This slightly longer shaft puts the slave cylinder piston further back in its bore, thus allowing a longer stroke and more disengagement. Installation is simple, and does not require bleeding the clutch.
(Although recommended.)

The Toyota version fits most transmissions, including MR2, Camry, Celica, etc.

Extend your rod!
