I driving e36 318is manual.diff 3.45 open.then I did the m40 flywheel mod..weight 10.2kg

Then I shave the flywheel to 9kg.felt very light.top speed still same.

Yesterday,I change to LSD 3.45..now I feel the flywheel like previous weight 10kg.maybe I should follow fab setup,7.6 kg flywheel..

Still have the 3.45 open diff..

that's strange.... Maybe the ratio is not 3.45 although the tag said so, could be 3.25 or 3.15... is the RPM the same at 100kph in 5th gear?
