I got the ACT one , either way 15lbs is too light. You should only drop maybe 15% of the weight.
Also note some drag-cars actually add weight to the flywheel. Only high rpm course racing will really benefit.....in stop and go situations the youll find it a bitch to get moving....it also makes it hard to get a proper launch at the 1/4 mile....as well as messes with driveability. Youll find rev-matching is a lot harder , revs drop real fast......and im pretty sure driving uphill with a lightweight flywheel is worse on acceleration......
But it would be an overal weight drop on the front of the chassis right over the suspension no less....which will improve responsiveness a good amount
It sure is a toss up....
