I just did a quick comparison of S1 S parts vs 4xx parts (clutch disc, cover, and flywheel) and the prior came out to 1104.10 vs 526.77. These were based on prices from DeRoure.

LotusLeftLotusRight Posted May 22, 2019 Report Share Posted May 22, 2019 I think you'll find the NA parts are much cheaper on DeRoure, if you can get them. It's the S flywheel that makes the above total seem so high. You presumably wouldn't need a new flywheel for your NA. Nevertheless, the 4XX parts are probably the best value option, especially if they are available now. 1 Quote Link to comment Share on other sites More sharing options...
Brendonian Posted May 22, 2019 Author Report Share Posted May 22, 2019 Just realised, the 400 flywheel probably isn’t significantly lighter than the already lightened S flywheel. Probably a noticeable difference for an N/A Quote Link to comment Share on other sites More sharing options...
Bravo73 Posted May 22, 2019 Report Share Posted May 22, 2019 FYI, the S never actually got the lightened flywheel in the end (regardless of what some publications/manuals might state). The 400 flywheel is the lightened flywheel, originally intended for the S. Quote Link to comment Share on other sites More sharing options...

I wonder what the difference is if not weight. Quote Link to comment Share on other sites More sharing options...
122 Posted May 22, 2019 Report Share Posted May 22, 2019 How do people find the feeling of the clutch bite point? Sharp/vague? Quote Link to comment Share on other sites More sharing options...

Sorry, didn't see your message until now. I'd say the bit point has always felt fairly normal, not too sharp, or too vague. It's very subjective, and depends a lot on what you're used to.

Brendonian Posted May 28, 2019 Author Report Share Posted May 28, 2019 Well, I have an 'interesting' update on my clutch situation... Lotus Silverstone have confirmed again that I should expect a long wait for a genuine Lotus replacement clutch. They also informed me that Lotus advised against fitting an S/400 clutch as the flywheel weight can cause 'calibration issues'. Not sure what that means, but I'd guess that means the engine is more likely to stall as the ECU has been calibrated to match the expected hardware. Silverstone have however found an alternative clutch option from a company called Oztilia Xtreme. These claim to have tested their clutch on the Evora, but I can't find any reports on actual customers out there on the internet. I'm not sure what to do: waiting it out seems to be the sensible/safe option. I've heard a number of reports here that the S/400 clutch is fine, but it would be just my luck to be the first person to run into problems. And it seems to be that the Australian clutch is every bit as much of a risk as a 400 clutch given that it's unlikely to have had a great deal of testing over an extended period. All advice/thoughts welcome! Quote Link to comment Share on other sites More sharing options...
au-yt Posted May 28, 2019 Report Share Posted May 28, 2019 (edited) Interesting that they claim the lightened flywheel will cause vibration, Unless the 4XX series has balanced engine, which I very much dought. remember the V6 Exige has been around for a while have a snoop on there forum and ask, lots of there cars have been tweeked. This is the link to the Australian listed clutch. and I would not be surprised if the guys at Simply Sports cars don't use them and they know a thing or two about competition build, not that is what you want but there experience should be of help. https://www.xtremeclutch.com.au/en/catalogue/xtreme-clutch Edited May 28, 2019 by au-yt 1 Quote Link to comment Share on other sites More sharing options...

The issue is ECU calibration. Presumably the ECU is tuned to let the revs drop to a certain point before trying to control the idle. The lightened flywheel will change the rate of rpm drop, and likely catch the ECU napping, so the engine is more prone to stalling. Im not looking for an uprated competition clutch, I just want something robust enough to deal with spirited road driving for many miles, and years.

Gold FFM C8RKH Posted May 29, 2019 Gold FFM Report Share Posted May 29, 2019 Reading his post I don't think @au-yt was suggesting it is a competition clutch. Just merely pointing out that SSC has extensive experience in performance clutches, including the rigorous demands of competition, so a potential good source of information and insights re that particular clutch. 2 Quote Alcohol. Sex. Tobacco. Drugs. Chocolate. Meh! NOTHING in this world is as addictive as an Evora +0. It's not for babies! The first guy to ride a bull for fun, was a true hero.

In fact it’s all the other information I have about that clutch that suggests it’s designed for more extreme use. Apparently, it’s rated to 400 lb ft. 1 Quote Link to comment Share on other sites More sharing options...

Ha - I was tired and a little drunk in my hotel room too! Must be a Tuesday night thing... Probably accounts for why I was winding up my 'Murican cousins on another thread too. 1 Quote Alcohol. Sex.

andydclements Posted June 10, 2019 Report Share Posted June 10, 2019 If it's normal clutch material, then I think I'd be looking at a local specialist to have the existing one re-lined. Slightly different if it was end of Autumn, but you don't want to miss the few decent months of good driving weather. 1 Quote Link to comment Share on other sites More sharing options...

andydclements Posted June 10, 2019 Report Share Posted June 10, 2019 22 hours??????? I can just imagine a conversation. Cust: how long is the job? Dealer: Just under a full day. Several days later Cust: Why are you billing me over 20 hours? Dealer: because we got it done a little quicker than expected. Cust: But you said less than 8 hours. Dealer: No sir, I said a little less than a day, there are 24 hours in a day. 1 Quote Link to comment Share on other sites More sharing options...

au-yt Posted June 11, 2019 Report Share Posted June 11, 2019 (edited) 222 weeks that's madness, If I can make another suggestion, there are companies that rebuild clutch plates for all sorts of cars, and sorry to mention the competition again but there the people to look for and spec a road clutch. Its probably an upgraded Toyota RAV 4 Diesel unit as that's what the gearbox is from. Edited June 11, 2019 by au-yt 1 Quote Link to comment Share on other sites More sharing options...
