for a stock car or even a pretty modded road car that clutch will totally suck.

Avoid paddle puck style clutches like this. It' may have a sprung centre but, it's not going to have much of a friction point.

Also the pressure plate is probably way over sprung. Again totally unnecessary.

Go the excedy style 9 button sprung centre clutch with something similar to the stock pressure plate for a mild road car.

that F1 clutch looks like rubbish..

Exedy are crap.

Go for an ORC clutch and flywheel - for something up to 250rwkw you only need a super single ORC unit...

I have been fortunate to have had an education in clutch selection many years ago. getting it right/wrong means alot to the whole nature of the driving experience.

Exedy aren't crap. they are actually very good for his application. They represent good value. I've used a single plate exedy 9 puck ceramic on both a nitrous fed gtst (with a stock rated pressure plate) and I covered bucket loads of kms and a few other gtst's and a gtr. Quite a number of friends have run these on even 400rwhp+ GTR's with no issue. The good news is they also drive very similar to a stock clutch and last.

ORC make great clutches for very high powered cars /race cars. But, they aren't great in the value for money stakes at this lower end of performance / power. They are double the price of an exedy easily.

The key is to select the right clutch characteristics for the application. The clutch is best thought of like you would brakes in many ways. Friction plates have a selection of compounds to choose from with different heat properties etc..

One of the largest stuff ups people have is in selecting a pressure plate that is sprung higher than they need. The bedding in and road going operation of the clutch is also critical. For example, trying to ride a multi plate race clutch for a traffic light hill start will see it die very quickly which tells you something about where that style of clutch was meant to live. Race clutches are also designed for relatively short life spans between rebuilds compared to road setups. They are afterall best thought of as a consumable like brakes.

I agree with what you say on getting the right bits that suit the intended purpose.

I still stand by my statement that exedy are crap. Even after talking directly to Kabel Davis who runs exedy Aust, I am still convinced they are rubbish.

Of the Exedy dealers i have had to deal with, most of them hate the product.

The reason for recommending a super single ORC clutch is that is a single plate that is still driveable on the street while being able to cope with increased power outputs of engines. We all boost things and play...

I'd like to point out that my 'experience' with exedy clutches is vastly different to the 'opinions' you have taken on board.

I tend not to stand by 'opinions' without some demonstrated experience to back it up. There could be plenty of reasons to bag out a brand. One that comes to mind is lower profit margins.

At the end of the day the ORC is a great product, but no better than exedy for this blokes application . Just more expensive.

Looks like an ebay special.

Rivited pucks, wow (All clutches even the cheap and nasty have rivets)

heat treated springs wow (pretty sure all springs are heat treated thats how you make em springy)

cnc castings wow (Generally a clutch pressure plate will have a cast iron unit machined flat cnc machned wont make any difference to regular machining)

i could go on.

i have fitted and driven many clutches

haven't tried an orc

exedy clutches are quite good maybe a little overpriced.

Extreme just as good as exedy but cheaper and have stronger torque straps

both exedy and extreme have clutches to suit different needs. ACS the company who make extreme will make pretty anything you want given 2-3 hours send em and the workshop or retailer will usually get next day. despite them being sa and im in melb

Talk to them both they both contact numbers on their respective sites and let them guide you.

do it once do it right. clutches are costly and so is labour.

My opinion i love a good brass/ceramic button sprung centred heavy duty clutch. you get used them. they feel strong ya know. not great stop start but hey.

also i was surprised how liveable a cushioned solid centre clutch was. dunno the brand it with the car an r33 but it was good for pullin skids.
