If the old ones (MY00,01) were faster it must be by a small amount if anything.

Why i think this-

* Lightier flywheel
* Smaller alloy wheels
* Overall Lightier?

Any idea's?

The bigger wheels and softer suspension make the newer cars a bit faster round the corners, so it evens it up.

The orange ones are noticably faster

Of course it goes without saying that the 53 plate Silverstone variety is the very, very fastest S2000 ever made.

Thinks its all even to be honest AJ

AJ, just find the official weights for the different MY, that will answer your line of thinking. I didn't think there was any change?

I agree ........apart from of course the 2001 in red

Smaller wheels on the same transmission would suggest a faster 0-60 time?
I know the tyre profile is different but surely the OD is less?

what year was the flywheel changed?

Hi I've just joined up having bought my S2000 6 weeks ago, I've been too lazy/enjoying the car esp in the snow to do this before, I will introduce myself properly sometime soon.

In the meantime on this thread, I had reckoned that a 225/50x16 and a 245/40x17 would produce exactly the same gearing. Sure enough, the Bridgestone catalogue I've got shows a rolling circumference of 1915mm for the 17, 1927mm for the 16, less than 1% difference. Any difference would be more down to tyre pressure, how much rubber you've burnt off today! Toyo and Yokohama catalogues show pretty much the same, give or take 2%.

Also I believe Honda tinkered with the gearbox ratios with the AP2, but we have only ever had the AP1, so no difference there early to late, yes?

What kind of weirdo collects tyre catalogues? my excuse is 10+ years involved in club circuit racing, trying to optimise gearing, corner weighting, geo etc all the time. TBH you can get the tyre info off the mfrs websites, I just find it easier to open a book
