My 2012 S is in for warranty work. Little niggles before the warranty expires. One of the issues I wanted them to look into was vague/notchy shifting. Much to my surprise, Lotus is replacing my entire transmission!! So, I have an opportunity to consider an upgraded clutch/flywheel. Honestly, I have no issues with the S flywheel/clutch set-up, but it's an opportunity to do a whole range of upgrades since I am not paying for the clam-off labor. I am concerned about drivability if I go much more aggressive than the stock set-up. Any opinions out there?
