This is Clutch Masters single mass lightweight version of the LTG flywheel. It is 16.2 lbs lighter than the stock steel dual mass flywheel which is worth significant racing performance gains. The stock flywheel weighs in at 31.3 lbs. However since it is single mass, you will have the infamous rattle at idle. This is more of a "race" product for someone that would rather have the performance gains and not mind the noise. This flywheel comes with a pilot bearing preinstalled and reuses the factory flywheel bolts.
High performance cutches have been a compromise since the beginning of their creation. Improving holding or clamping pressure will almost always increase pedal pressure to an uncomfortable point, especially for stop-and-go driving. Clutch Masters advancements in clutch technology has allowed them to increase the overall holding pressure without the increased pedal pressure and problems that come with it. Clutch Masters has been in the battle of man vs machine for as long as they can remember, but with each improvement in technology they are able to provide higher quality clutch plates that are both durable and efficient.
