The 10# flywheel that Tilton makes (never knew Centerforce made one. Do they?) is not really appropriate for the street unless you are willing to give up some driveability. Car will kill since the flywheel doesn't have the weight to keep it spinning. The more appropriate method is to have yours lightened and balanced to about 16-18# This gives you a quick spinup without the loss of street manners.
centerforce only makes an aluminum flywheel in the smaller 225mm size, not the 240mm 2+2 and turbo size. if you want a lightweight one that size, go to arizona z car, www.arizonazcar.com their price is almost the same. but it is 10lbs and steel vice 13 and a combo of aluminum and steel. better in my opinion. i have the centerforce, and claims of reduced driveablitly are crap. i have heard it many times, and it just doesn't hold wind. mine drives eaiser than lots of other cars. the l6's torque makes it easy to drive, vice a wimpy 4 cylinder w/no torque down low. and it isn't my 3.1, for other cars i have been in, have them, and they are fine. it does make a noticable difference.
