Light Flywheel Question

Just oredered a ACT Streetlite Flywheel for my S5 Turbo project. They guys I ordered from said that it doesn't come with a counterweight but instead needs the counterweight from a automatic FD. Does anyone have this flywheel and is that truly the case? This may be a dumb question but it just sounded kinda weird to me. Any help would be appriciated.

YES FD rotors are the same as kouki TII rotors you need either one's counter weight. But since TII's did not come auto in the states you can't find them that easily.

Could you use an automatic counterweight off of a non turbo 88 model?

Bad idea - The S4 & S5 rotors are not the same weight, so you would be out of balance.

oops, I was thinking about my series 4 motor, did not read he was using a series 5. My question is that it doesn't matter if the counterweight comes off of an NA model right as long as it's for the correct year, 86-88 or 89-91?

This brings up ANOTHER point..... are s4 NA and TII rotors the same weight since they are different compression??? Cause when i put my lightweight flywheel in my TII I used the only thing that was available... an s4 NA auto counter weight??????? Car seems to run fine, but come to think of it... I've never seen an automatic s4 TII.
