Another point worth mentioning is in turbo cars the heavier flywheels help the engine to keep the revs up during gear changes therefore keep the turbo spooling better - which is why I have a normal weight fly on my car.

I don't know if there was perhaps a design fault with earlier Lexus flywheels perhaps ?
The trouble with dual-mass flywheels is that if they do develop a problem, you can't just skim them to fix them, they have to be replaced.

22-10-2016, 11:56 PM #10There are differing opinions but some people seem to have found that replacing the flywheel can cure the juddering. Replacing it with another dual-mass one from Lexus can help, not just lightweight ones. However the problem is that the Lexus ones are about twice the price of the lightweight one.
