That ad' is very misleading. I'm not that certain w/Viggens or 9-5's, but on 9000's the weak link for torque values above 400-425 Nm of torque is the pressure plate - not the clutch. A stock Aero clutch is more than sufficient for 500 Nm, provided it's used with a capable pressure plate. Unfortunately, there's not many choices for a 'capable' pressure plate. Sach's monopoly position is reflected by their price - it more than doubled in price, a few years ago.

The way I read it is that they are selling the design on the fact that a paddle friction plate with the std. pressure plate will grip better than a non-paddle friction plate.
I sort of see where they are coming from but the difference might be too marginal to be of real benefit.

Just a thought, but does the AP Paddle clutch actually use a stronger pressure plate?
If so, then I could use the AP pressure plate with a standard friction plate.
If AP use standard pressure plate forces then it supports the sales pitch in the paddle clutch I have linked to.

hmmm

You retain the standard pressure plate when you fit the AP paddle. It's only 4 paddles compared to the Swedish Dynamics 6.

I've never had even the slightest hint of slippage on the AP with just short of 500NM.

I too have never had any slippage with the AP clutch, while a standard clutch was slipping after only 30k miles. My car was putting out 450Nm of torque.

Mind you, I couldn't even slip it when I wanted to, which made driving in snow almost impossible

It was probably that exercise that caused the AP friction plate to chew through the flywheel and pressure plate. I finally ditched it in favour of the Sachs pressure plate and a standard friction plate. Expensive but much easier to drive, although crawling in traffic gets a bit hard on the leg muscles due to the increased pedal pressure.

that's great info - cheers.

SO - there is a potential that this Swedish Dynamics paddle friction plate + standard Pressure Plate will sit somewhere between AP setup and fully standard in both agression and grip?
(based on the fact it has 6 paddles,not 4)
If so, it could be a great potential alternative for me.

One other confusion I have is, if the AP clutch uses the standard PP, how can the action be heavier? (or is that mis-information also)

It's not. The action is as light as the standard clutch but with a rather more sudden "bite". It is the Sachs Racing pressure plate that produces a heavy action.

Thanks for the info. - Given that I want to keep the clutch as 'light' as standard (i.e. not very!) and the Sachs pressure plate is also rather expensive I may actually end up with the AP clutch
1) Its available in the UK
2) Lots of people have used it - it has downsides but fits and works.
3) Sounds like it will last a good 50k+ miles.

tbh - The Swedish dynamics one is a bit of an unknown and given the effort of fitting one...I'd rather not gamble.

Also - been quoted 6 hrs labout to fit clutch and slave cylinder. Sound normal?

Labour is about right. Don't foregt that wehn you repalce the AP paddle, you'll also need ot repalce the pressure plate and probably have the flywheel skimmed. It's brutal.

I assume having the flywheel skimmed might be an extra £50 or so onto the next clutch change?

Also realised the AP paddle doesnt come with a pressure plate and I can only seem to get either an original Saab PP (£120) or a full Sachs PP and FP (£150). So overall not as cheap as I thought.
