I know its an unusual request, but my wife can't understand why the clutch for the TVR is so expensive (well under £100 for het Clio!), so, I tried to explain that's its a special 'racing/performance' part that bears no resemblence to the Clio one at all, is that right? Has anyone got any pics of one, so I can show her, I have done a search on the net but to no avail.

(SP mentioned that my clutch was biting a tad high (stressing, yet again nothing to worry about at this time), and I asked the cost of replacing it in the future, and it's a four-figure number)

Oh yes, and please explain to her why simply fitting a Clio clutch wouldn't work all that well!!!!

Tuscan Bev has got some nice SEM pics of bits of a S6 clutch. Got them done at work to see if a failure (at <20k miles) looked like fatigue or frature.

I'll see if I can get a copy, but I'm not sure they would help!

Cheers Andy , I too was told today that these clutches 'realistically' last only for around 20K miles, but I would have thought it was dependent on other factors, like how hard the host car's driven?

Mine had a new one just before I went to the Alps last summer, after about 17k miles, 2.5 years old.

Don't think I used it particularly hard so that might be how long they last. Perhaps you should try a clio one

Well it is a high performance clutch made from tibetan yaks hoofs so its suited to a 400hp car, so the parts won't be cheap as a Clios. Its not a common 'off the shelf' component too - handy to keep the prices up - just like front brake discs on our cars. I assume a lot of the cost is fitting of the parts too.

Cheers That is a ggod pic, wanted her to see the 'fingers', around the centre, which tend to break off,, and I almost had her believing that the clutch was really made from tibetan yaks hoofs!! lol

Typical, got the car back, 2" of snow in the Forest this morning!

I am sure she will not see that clutch as being worth any more than hers, the real reason cannot be seen. The "fingers" look the same as any two bob clutch.
The diameter of a clutch goes up with the power output of the engine. As your car has serious output it would need a clutch the size of a dustbin lid to harness the power without falling apart. Having a clutch this large is impractical so they effectively split the power between two clutches next to each other, enter the multi plate clutch. They manage to do that with plates and spacers and cleverly get away with only one cover still, but it is almost like having two clutches. A compact multi plate clutch has all sorts of forces/heat to contend with so the manufacturing process is different and more expensive. The higher clamp pressures mean the hydraulics are under more pressure(excuss the pun) which results in other problems and expenses.
In short the reason your bill will be bigger than hers is that her car is feeble and yours ain't, it is also a well known fact that bills for cars with multi plate clutches must take precedence over all household bills

Cheers. perfect explanation , just made her read it, and she (and me!) now have a better understanding. ( as someone yesterday gave me a deeper insight into the pros and cons on the 2 different diffs and ratios fitted on TVRs, and why some new cars are slower! )

Another quick question, my clutch is biting very high, so I think it will need replacing sooner rather than later - are the new batch of AP twin plate clutches of a revised design, so they last longer than 20K miles? Also, I note the price is around the £550 mark including the vat, has anyone bought the clutch seperately and then had it fitted?

Just trying to think ahead.....



Cheers

Not that I'm in any way, shape or form paranoid, of course!!!!

I doubt you'd get it fitted PROPERLY any cheaper than somewhere like Silverstone Performance.

What happens when you buy one yourself, pay to have it fitted and it goes bang because it is faulty?
If the garage supplied it then it will be their problem, if you supplied it then it will be your problem with resultant labour charges. Not a good place to be.

Not sure how relevant to this thread these are (or if anyone is interested!), but - here are some nice clutch pics. They are looking at a fracture site on one of the fingers.

Are those the latest Mars pics? Wish they didn't fracture so soon! - interesting pics though, thank you

Since being told of my 'impending clutch failure' I have since become paranoid, and I have found myself not using the Tam () for fear of being left stranded for hours!

Today, for instance, I have always picked my son up in the Tam, but I daren’t today, if I'm late, my ex is as forgiving aa a nutty Muslim cleric with hooks on the end of their arms!

Not an enjoyable experience at the mo, I feel like booking the damn thing in to get the clutch changes, may be worth it just for piece of mind - so I can drive it without this black cloud hanging over it!

I think at 2000x mag it would probably look pretty much identical to the clio. (or Mars)


When my clutch went it was pretty 'progressive' (if that is the right description). I think the fingers fail one at a time.

Anyway - I was able to drive it 30 miles to the dealer to get it sorted, so I'm not sure worrying about being stranded is a good enough reason not to drive it!

Take the RAC card and enjoy the spring.

You're right, I worry too much - and - after just getting back from picking my son up in the Clio, I wish I had taken the Tam, after being 'bullied' no less than 3 times on the road by 2 Focuse's (Foci??) and a fake M3!
