aluminum flywheel

**SSpeed** · 09-10-2007, 05:35 AM

Are there any cons to putting in an aluminum flywheel. I have to do a clutch replacement and might as well replace the flywheel while im in there. Where's the best place to get a good clutch and aluminum flywheels.

thanks for the help.

Street car and drag cars should stick with billet steel.

AutoX and road course cars should go aluminum.

Mine is billet steel by choice.

Stay with the Steel one if its a Street/Strip Car.

I would't worry to much about it there are alot of people running aluminum in dd with no warping. Steel will warp as well, aluminum flywheels have steel inserts with a small gap inbetween that allows for expansion due to heat. These inserst can be replaced if they do by chance become warped with out haveing to replace the whole flywheel.

I more than likely will be running aluminum with and ls7 clutch. Have't 100% decided, I'm reallly hoping someone will come out with a ls2 steel billet flywheel so I can go with that but as of now no one makes one so I'm stuck with aluminum or steel.

Go with steel unless your doing lots of autoX or road course.

I run aluminum in my wifes daily driver with no ill affects at all.

My biggest reason for going aluminum was the fact that there are not any shops around within 50 miles of me that will machine a steel flywheel every time I do a clutch job,,,so rather than drive all over town I simply went with aluminum,,,,Fidanza to be exact. When it comes time to do the clutch there is no machining of the flywheel,,,I simply remove the steel insert and replace it. There is no down time and no running around town waiting for someone to turn a steel one. Making 2 trips etc....this was reason enough to go aluminum for me,,,much less hassle. I can have the car done and on the road in 2-3 hours.

Don't notice any difference in the car as far as driveability or performance,,,but thats not why I did it anyway,,,,hope that helps.
