I was in Toronto today to see some cars at Performance World. I saw Da Sivila there and asked them about the UPR clutch quadrant and FW adj. Thay said That it WILL NOT work with a stock oem cluch cable and I told them that I was pretty sure it would. I wasn't planning on buying theese from them cause I just got them off ebay but I acted interested to get a bit of info from them. He told me he puts down 500 hp to the wheels and still running stock quadrant and cable. Then he asked why I want it is your curren't stock one broke. I said no I was just looking for some adjustability and a nicer clutch feel. So to make a long story a little shorter he was kinda rude to me and talked me out of buying from them (didn't plan on buying something I already bought anyway). When I left them I seen the Ford Racing booth and asked them if the Quad and FW adj would work with the oem cable and they said according to thier book it says the Steeda stuff will so there should be no reason the UPR wont. Was I right or did I make an ass out of myself.
