Question: I have a SoCal 1991 Convertible with 67k original miles. I have added a Bonez intake and Bonez less restrictive Cat system coupled to a Racing Beat Cat back exhaust. I have added Tokico Shocks and Hawk pads. Now am considering the Racing Beat lightened flywheel with their heavy duty clutch set up. I only drive the car on the street and usually just on weekends( 3000 miles a year)
Is this setup worth the money($600+) in improved performance or is this something that is meant more for Competition driving? Will I feel a definite increase in performance that will not diminish the current great feel the car has with stock set up? I want to find improved performance any way I can short of a very expensive turbo swap. Appreciate any advice from those of you with experience with Lightened Flywheels. Thanks.

 

Swap out your diff with a GTUS 4.33:1 model and you will notice drastically improved accelleration.

Vert's have a tall 3.9:1 diff that eats up performance.

 

I'm using an act hd clutch and 9# alumnimum flywheel. It makes a huge difference in acceleration. I forget what exactl they say, but dropping 20lbs in flywheel weight will make the car accelerate like its 200 or 300lbs lighter. No sacrifice in driveability either. I can still lug the clutch in traffic at like 500rpms to keep the car rolling.
