I spent yesterday at Sandown Raceway in Melbourne and put around 240km on the car at competition pace.

Got down to PB times (high 1:26's) but noticed that the clutch was starting to slip on 4th to 5th change, and if I slowed the change so that the revs matched, the slip was not so noticeable, but in the end, it eventually saw me fold for the day.

It recovered enough for the drive home having let the car cool for 45 minutes.

So now I need a flywheel and clutch.

I can see JWT offer a package, but I am interested in alternatives, especially as the car will get a big weight diet, HR head conversion and sequential shift gear box in the medium term, but for the time being, will be DD, so a sprung centre is mandatory.

What is the range of alternatives - I'm keen to have any feedback.

I've already PM'd Valkyrie MotorSports and the Doran Racing guys, but I suspect they will use a solid centre race clutch which won't suit my immediate requirements.
