Looking at getting the UDR Flywheel or Fidanza. What can I expect as far as gains from either and how difficult is it to install? I have my stock UDP. Would you guys recommend it? Thanks for any advice.

 

Difficulty is on par with a clutch job, so personally I'd do BOTH at once, ie upgrade the clutch at the same time as the flywheel.

I like the Fidanza, since it isn't as light as the UR. Your driving technique doesn't change much with the Fidanza, but I hear the UR takes some getting used too. Also, if you get the Fidanza, later you can try the UR UDP and see if you like how the clutch/flywheel engage. If you get the UR, you're kind of stuck with it.

Also, you won't GAIN any hp/tq per say, you'll just not be losing as much. In first/second gear the revs will happen quicker, but in the 1/4-mile your times will actually get slightly worse from loosing the momentum the heavier flywheel provides.

 

Do I search on both. Or refer to my for sale link in my sig. It has valuable reference information.
