My Tuscan showing signs of needing new clutch.

It has done 44k and this will be its 4th clutch.

I don't trash the clutch. I have been lead to beleive 10k miles is normal life expectancy, I am not convinced

Anyhow anybody tried these?

Mine was replaced at 13k when I had the clutch slave cylinder replaced, they said it was 50% worn out, if that helps.

The helix clutch is good, as is fully rebuild able so the next replacement should drop in cost.

My car drives better with it, but theoretically any new clutch will and the diaphragm Spring fingers become work hardened over time and give the impression of a heavy clutch.

Even when I used mine as a daily driver with lots of time stuck in crawling traffic I got c.25k miles out of a clutch. I hope whoever said 10k is normal doesn't fit clutches...

Or perhaps they do... And want more business?

I went for the helix option and had it fitted about 15 months ago; the original clutch gave up the ghost after 25,000 miles. Very happy with it, no issues, works well.

Mine's still on its factory fit first at 55k.... Won't be gambling with a Helix went it finally goes.

Why an earth would you think it's a gamble. Have you ever handled both clutch packs. You've seen the latest AP hassle haven't you. The bad batch of helix clutches came and went...

Real experience of product A, only hearsay and opinions on product B. Generally human nature is to trust A over B. A decision based on no personal experience is naturally a gamble (odds on each being a completely different subject matter). Having an engineering degree I do understand theoretical improvements but having spent my working career in aviation, we tend to be a risk-averse lot. Same thing happens with my tyre choices although those Toyo's are tempting next time around.

Presumably your real experience is pushing the clutch pedal. I come from three generations of engineer (although I'm in business) so understand your philosophy.. But I can assure you from an engineering perspective the helix unit is at least equal and from a qualitative perspective is finished to a higher standard.

In addition to that the helix differentiates itself in the fact that helix will supply every single component to rebuild it. AP will not, they force you to buy a new unit. The AP unit has issues with the star washers holding the thing together and the diaphragm Spring... From experience of disassembly of my failing AP clutch there was nothing wrong with the friction surfaces..,

Strangely my day job is risk management.

Hope this helps.

Mine was replaced 6k ago with an AP unit and a replacement slave frown and is showing issues. Problem seems to improve with use, but gearchange is at times stiff to engage, crunchy from cold and sometimes shows (but not always) that the clutch is dragging slightly; car moving whilst clutch depressed in gear etc. problem statrted last year after service when fluid was changed but improved after a few weeks and a bit odf use. There doesn't seem to be any loss of fluid and clutch seems to feel in the right place most of the time. Its going in to be examined next week ... i know if it is the clutch that i will opt for helix over this

I have an AP clutch which has circa 20k on it.

I had the box out about 5k ago to change the slave which was leaking, the clutch at that stage looked ok so I refitted it but did have disengage issues which related to the starlock washers (as mentioned by M4TTI), as soon as I replaced them with manufacturer approved washers the clutch was fine (these things only cost £1 each); I also moved the clutch round on the flywheel to avoid the wear grooves where the butterfly springs press from clutch to flywheel. Touch wood the clutch is still going strong.

I subsequently fitted a Helix clutch on a friends Tuscan and had a whoor of a job, this turned out to be related to the faulty plate scenario. My issue there is that TVR and Helix knew there was a problem yet opted not to advise on this despite several phone calls to them about the difficulties I was having.

For the above reasons alone it will be AP for me when the time comes...
