Description

The ACT 600125 is a Prolite flywheel, which is ACT's lighter flywheel offering with lowest inertia. Prolite flywheels are designed for best throttle response and acceleration. Prolite flywheels are preferred for road racing or rally racing, and have reduced drivability. Materials are properly distributed for maximum strength, good heat tolerance and rigidity. ACT flywheels are serviceable and can be resurfaced with no need to purchase additional parts.
  • Product Weight (lbs.): 8.5
  • SFI: 1.1
  • Dramatically improved engine response and acceleration, mild to moderate gear rattle
  • Heat-treated forging for strength and toughness, induction-hardened ring gears for maximum life
  • One piece construction allows less opportunity for failure and provides uniform efficient heat transfer from the clutch disc. No more warped inserts or loose ring gears
  • Recommended for race use
  • Forged, CNC machined and dynamically computer balanced for smooth high RPM reliability

ACT ProLite Flywheel
Mike K. | June 23rd, 2010
I definitely give this product props thus far, I've noticed gains not as much as one would think but they are definitely there. Works just fine for daily driving the revs do raise and drop faster but it is not anything that takes away from daily driving that one might expect. When you wanna get on it a lil' it's nice to rev faster however your shifting needs to be spot on or you will not keep catching lift in subsequent shifts due to the faster RPM drop. Goodstuff though, just make sure to install a new clutch at the same time, not before-not after. My clutch went out 1 month before my flywheel, I had my original flywheel resurfaced at that time. My original flywheel was finished shortly there after. I was stuck paying for the same costly install twice in a month.

I have to say this flywheel is great. RPMs just fly by and when they settle they dont take their time. I noticed the difference over stock right away. I have to say I love it and getting into gear is easy. It is just a all around great buy I would suggest it to anyone.
Sweet!

Having given up on waiting for the streetlite, I finally decided on this model. I was a little skeptical based on peoples posting here and whether it was "streetable". After the first five minutes all doubts were cast aside. RPMs flew by and I didnt have difficulty getting into first, or stalling it. The RPMs do fall faster than stock, but it hasnt been an issue to me. Great buy and great prices here at
