D-Sport / DRS 3 Paddle Clutch Kit - Made by Exedy Japan

 

Imported direct from Japan. Limited stock and soon to be discontinued.

 

This lightweight (620g) and strong cerametallic clutch disc features bonded material rather than the usual riveted. So you get full depth of lining wear without the worry of wearing down into the rivets.

 

Offers a torque increase over organic of around 15-20% and will not fade and slip due to heat like organic does. 

 

This is 170mm as opposed to 180mm but still fits GTti pressure plate and flywheel perfectly fine.

 

Be aware some judder when pulling away from a standstill is often experienced with this type of clutch disc (gets bit better once bedded in).

And engagement is fast.

 

Sold as a 3 piece kit with the 20% uprated pressure plate and release bearing (as shown in clutch/drivetrain section)

 

This will hold torque up to the gearbox safe limit of approx 150-160 lbft. 

 

Disc, +20% Pressure plate and release bearing.

T25/T28 Flange

 

Available with external wastegate branch (as photo)...Or without.

Superb Quality, Hand-made by Fusion Fabrications here in the UK.

 

Popular T25/T28 flange...To suit a large choice of turbocharger sizes.

The downpipe will be your own responsibility to get custom made on the car. Unfortunately we cannot supply downpipes due to the many differences in turbo sizes and exhaust pipe configurations. But the manifold is the hard part to make!

 

Remember you will also have to consider the other modifications required for a setup like this....Such as turbo oil feed and oil drain (back to sump), Air filter and boost pipework, etc

With external wastegate branch...£ 550 

 

Without...£ 475 

 

Please allow a few weeks before dispatch...This is made to order.

Multi Layer Steel Head Gasket

 

This MLS head gasket is exclusive to GTti Developments.

Features 3 layers of Stainless spring steel. With heavy embossing on the outer layers.

The inner layer also has firing rings.

The gasket has performed amazingly well since it's debut a few years ago, over 20 have been sold and used on some of the most powerful GTti / GTxx's on the planet!

 

However be aware this gasket is NOT the only cure if you are regulary blowing normal head gaskets. In this case you need to look at your engine tune!

 

For most people's usage I would still recommend the standard type composite gasket, which offers a easier installation on less than perfect surfaces. This gasket requires a high standard of smooth finish on the cylinder head surface and engine block. Best fitted if performing a total engine rebuild.

 

A light spray coating of gasket sealing spray (such as "Permatex copper-spray-a-gasket" or "VHT Gasket Cement", search google or ebay) is advised to ensure good oil and water sealing.

 

These are made a little thicker than factory gasket, 1.4mm to compensate for a minor head and block skim.

Thicker can be made no problem, Up to 2.0mm

 

Usually made and sold to order, But sometimes I have a few in stock.
