JWT Clutch & Flywheel

Recommended Posts

Back in Feb/March @Sly@Kaizer Motor Kaizer Motor rebuilt my gearbox after a couple of failing parts (5th done, and R going).

Whilst they were doing this I thought I may as well upgrade the clutch and flywheel, and considering I had no idea what state it was in I'm glad I did.

 

I knew I wanted the JWT kit as I've only read positive feedback from it, and considering the car gets tracked I thought this would be a good way to go.

You'll find more reviews I think on the US forum, for ex:

@Adrian@TORQEN kindly got the kit out to Sly, including a StopTech slave cylinder:

My car has Vibra-Technics (road) engine mounts, Torque Solutions gearbox mount and Whiteline diff mounts.

 

Unfortunately I don't have any photo's of these parts as the guys had things fitted and ready to go when I was able to get there (lots of snow back then!). However I do have the old clutch/fw in the garage so I can show you the condition of those.

As soon as I fired the car up and set off down the road I could immediately feel the difference.

It's far smoother to operate, and rev matching is still nice and easy but perhaps you need to be a tiny bit quicker on the blipping due to the flywheel.

Yes the flywheel is quite noisy as expected when idling, however this is normal but you don't have to go that route as you can choose a quieter one if desired.

I did get one track day in at Anglesey back in the summer and it performed without a hiccup. As the track was new to me I wasn't really paying a whole lot of attention to my car :blush: (aside from braking/tyre pressure).

I'm sure anyone else with the JWT kit will attest that it feels a hell of a lot nicer and engaging (sorry) to use over an OEM set-up. 

 

Any questions, fire away.
