I assume in the 260 it’s just a bit more Rev happy?
Current one weighs in at just over 6kg, the one I've gone for is 4.5kg which isn't the lightest you can get (Fidanza do an aluminium one which is 3.5!!).

I'm cautious about going too light as it can make low speed driveability a bit awkward, so went middle for diddle really. I'm not too sure how light the Cup 260 one is though.

I only drove a 260 sedately, but it felt a fair bit more responsive particularly whilst rev matching and lower down in the revs.

I had the Fidanza flywheel, oh my does it rev, however, it is a real pig in traffic when it gets really hot. It would not disengage correctly and drag, all down to the flywheel expanding in the constant heat. Ended up parked at the side of the M25 once for 45 minutes to cool down while the traffic started flowing better.

Yeah that's the main reason I didn't go as light as possible, been there/done that. I had to get my Civic on life support this weekend in preparation for if/when the missus goes back to work this week and I've always loved the flywheel feel in that. Appreciate the K20 is not a 2ZZ but if I could get a similar feeling setup in the Exige I'd be quite happy. (According to google the FN2 flywheel is around 4.5kg).

All the suspension is now off the car, no bad surprises really - the bushes are in OK condition but a couple of them had walked out a bit... so they will get replaced.

Obviously will get it all tarted up too, got new bolts/fixings to go on too. I replaced the NS wheel hubs last year after I managed to break the speed sensors on both( :| ) so will stick some new OS ones on this year too so at least I've got the full set.

Finally past the point of no return with the gearbox and I've sent it off for rebuild.

I've been back and forth on this more times than I care to count, should I run it to destruction (if ever?) and fix it then, or be proactive and try to use it as an exercise to optimise performance a bit more? The big sticking point was the diff, I really wanted to try one in my car and I just couldn't justify the cost and effort of install without doing the strengthening stuff whilst at it.

Obviously I decided to go ahead, still not sure if it's the right decision or what - hopefully I've not ruined the car and hopefully it rewards me with years of happy motoring and trackdaying... we shall see.

I opted for the following 'upgrades':

Image

SSC 3rd and 4th gears, same ratio as standard - just chunkier, and still helical so hopefully not too noisy.
Kaaz 4.8 Final Drive
Longer 6th gear from a Corolla/Celica
TRD LSD from an MR2

Added to that I've got a Stage 2 clutch and lightweight (4.5kg) flywheel from Competition Clutch:

Image

What I've calculated to end up with looks something like the following:

Image

Effective wheel torque should be +10%ish through gears 1-5. At most circuits I go to regularly I'm at the very top of fourth and usually short shifting into 5th just to give me breathing room coming into the braking zone. I expect to be using more of 5th now, and hardly any of 2nd (if at all). The change I don't think is too extreme, it was very tempting to go all in on a very short box using either Kaaz gearset or a 5.0 FD with stock gears but ultimately I leaned towards a more conservative setup.

The diff I know is a controversial topic, I don't think there's a clear right or wrong answer for the Elise platform so I just need to try it myself. Fingers crossed...

Gearbox is with a local specialist (http://www.stephenbreargearboxes.co.uk/) who do a lot of Toyota stuff and I have a few first hand reviews of their work in Lotus circles too so hoping for a top job. :thumbup:

Jury is still out on gearbox cooling, from the temps I logged last year I'm not convinced my stint lengths would benefit from one, but I shall continue to log temps and I will of course add one if needed as the new gears may generate more heat just through altered tolerances etc.

Suspension is also off to Chris @Type116 for Zinc plating, I'll topcoat it with something (probably POR15 clear) when they get back.

Anyone who says you dont need one is wrong.

:thumbup:

( and good progress. I shall be watching with interest )

Well..... I got a PAX with Matt Becker at the Lotus 60th at Hethel.. we were in a 111R with an LSD, he said he didn't like them as it pushed to front too wide, especially out of the top corner there.... with Gavan Kershaw in a 211 at Snetterton, he said he preferred it (in a 211)

I've spoken (and driven) with people whose driving ability and Lotus experience I respect a lot. Some love the diff, some say it's OK but not mandatory, and a couple say it spoils things.

Certainly I think the higher power gets, the more beneficial a differential will become.

I really think it's something that everyone needs to try themselves. There was probably a cheaper and easier way for me to conduct that experiment, but hey-ho :lol:

sure it will be great - I think it depends on your driving style as you say.... I had quaife LSD in my Talbot Sunbeam race car back in the 90s... could drive it sideways for miles... epic ! :)

I look forward to hearing your views on the LSD when it's all finished. I don't have Lotus specific LSD experience but from the car's I've had with/without one I believe if you are comfortable with oversteer it makes for a more predictable handling dynamic when on/past the limit.
