If you have an (999) S, don't bother, it already runs a lighter flywheel as stock. Not as light as some people run, but never the less its a few hundred quid for marginal gain on that particular model assuming street use is intended.
When my 999s was being fettled by Sigma Performance we discussed fitting a lightened flywheel when the motor was in bits and decided it was more beneficial to spend the money on something else. The weight saving on the flywheel was only a few grams. The wallet lightening however was considerably more!!
