Available now: Uprated MKIV TT clutches.

 

 

I use the stock, brand new driven plate, as it is correctly

balanced, doesn't judder and will hold all but mega torque

highly modded engines or cars used for drag racing.

I modify a stock brand new cover to give more clamping force.

The reason I tooled up to do these is some of the aftermarket

US clutches I have fitted SEEM to be built from used cover

assemblies with reground friction surfaces, and a stronger

spring. I have had hellish trouble getting these to fully

release, because due to this seemingly thinner cast iron

friction face, the geometry of the clutch goes to pot, and

being a pull type clutch (the hydraulics pull the bearing

away from the engine, rather than the more normal push type)

it is a lot harder to effect a cure.

 

For 455 pounds plus VAT , you get a brand new driven

plate, a brand new modded cover, and a brand new release

bearing. I would rather fit myself so any complaints are down

to me, I see a lot of clutches damaged by people without the right gear

(a ramp and transmission jack, plus correct circlip tools and fitment)

or clutches fitted to patently knackered flywheels. I will do a supply

only if you feel competent to tackle the job or are using a bona fide garage to

fit the clutch. Clutches damaged by incorrect fitment will NOT be considered

for exchange, be SURE you or the garage know what's involved and have

the right gear.

 

 

Toyota use a dual mass flywheel (the flywheel is in 2 parts, an inner and

outer assembly, damped in the middle) which is now showing signs

of wear causing a lot of rattle when idling or on very light

throttle openings. For God knows what reason they are charging

about £400 + VAT for a new one, they look more like they should be

over 500 to me, but don't say anything :-) The very similar LUK dual

mass flywheel on Maseratis is nearly £1000 + VAT.... So if the flywheels

old enough or abused enough to be scored, or it has movement beyond

the Toyota workshop manual limits it should be replaced.

 

Having me fit the clutch and / or flywheel will cost £175 + VAT labour.

 

They are in stock now.
