Probably a noob question, but I see alot on these forums about lightweight flywheels for 6MT but nothing about lightweight flexplates for a 5AT. My main objective is to effectively make it so that less HP gets wasted through the crank and put more power down to the wheels as well as better acceleration. Does anyone know where I can find some aftermarket lightweight flexplates for an '08 TL-S 5AT? I've Googled tirelessly with no answers. Or are there other ways this can be achieved?

 

Flex plates are already pretty light, from what I understand...

 

If you cannot do the work yourself (and it is not an easy job), it will cost you two to three thousand dollars to put in a light weight flywheel; in return you will get virtually zero improvement in performance. Don't waste your time and money.

 

Flexplates are relatively light and have a tough job to do, torque converters are heavy and filled with ATF fluid. If you could find a lighter converter that would be a better option. Or just get a lighter crank pulley... will have about the same net effect.
