Does anyone have any experience with zoom clutches? Are they worth a damn?

 

Never even heard of them. Just go with a proven clutch, like Exedy, OEM or ACT. I've used Exedy (organic) with good success.

 

I have one in my Celica. It was put in by the previous owner. I hate it and would also recommend something with a better name. It's engagement can be jerky and it's holding power seems to fluctuate with ambient temperatures. In the heat of summer it slips a bit, but the rest of the year it's ok. Going on 3 years of this crap, ever summer is sucks.
