K Series 184mm clutch

Well it has been along time since my last update and much has happened, to be detailed in a new post with pictures and everything. Basically had the quartermaster clutch fail spectacularly by stripping it’s splines at my last event. I have a theory on friction products, if they are not AP they don’t work. Pretty much the problem was that because the quartermaster was a rally clutch with 2 X 1/4" thick plates the spline on the gearbox was not wide enough to house both splines and the cover would snag on the bellhousing without a spacer plate.

Long story short put the 215mm clutch back in and ordered an AP 184mm twin plate sintered clutch, which all credit to the agents here arrived 3 weeks ahead of schedule .

The entire assembly of weighs 2.8kg’s less than std, which is not to bad considering it has an additional plate and intermediate plate. Must be honest and say that it has felt like a bit of a tractor with the std clutch and flywheel, not as 2 storke as usual. Amazing how quickly one becomes accustomed to stuff, used to think the 1.8 was pretty free revving until I experienced this.

Sorry about the size can’t find my editing software to make it smaller.

Other notable additons are 3 way adjustable dampers and a few other bits and bobs. As soon as I find the time I will do a detailed thread. In short the car has been fantastic showing an improvement of just on 5 seconds over the best times aschieved with the 1.8, yes I have data logged to prove it, all in the forthcoming post.

That looks a beast! it looks like a oversized bike clutch

Interesting stuff Jason. Just to jump to the defence of Quartermaster though, I’ve been running a 5.5" solid centre twin plate for over three years now and there’s never been any issues with it, admittedly I run AP friction plates in it. The modified (ie round nosed) release bearing even fits onto the standard release fork.
