Subject: Re: planning my attack by Josh on 2010/10/6 2:48:04 What kind of power are you making? I haven't ever used the spec stuff on a ZF6, but I've done a ton of clutches on our cars. Since you have the spec flywheel, I'd go ahead with their clutch. If you didn't have anything, I would recommend the centerforce dual friction with the Centerforce steel flywheel. That's what I have now, and I like it. I've used a McLeod twin, and while it drove like a dream, it was brutal beyond belief if you were dogging the car. A few years ago there was a company in California that was making stock replacement clutch disks. You could get a stock one, or a hardened one. I don't really know what they meant by 'hardened' but I used one of those for awhile in a 92 Corvette and really liked it. However, since you don't have the dual mass it's a moot point. You can get the cast replacement hydrualic parts through CarQuest. They have one part number for the slave, and sometimes the box will have a plastic one in it and sometimes it will have a cast one in it. Just have the parts guy open boxes until he finds a cast one. On the master, the parts guy will probably tell you it isn't available. Have him take the CarQuest part number and cross it in the WorldPac system. It will cross over, and that part is a cast unit. Be sure to take both units apart and clean the bores. I've done over 20 clutch hydraulic jobs and every single time the bores on both the slave and master were full of debris. You can also double check the orientation of the seal in the slave. If you use a cast slave, you'll have to use new nuts with no flange on them (the OE nuts are flanged) or grind a bit on the slave so that a socket will fit between the nut and the slave. I don't recall the thread size at the moment. I prefer the B&M shifter, but anything is a huge improvement over stock. I think my transmission shifts better with the GM fluid VS the Castrol, but it could just be the placebo effect. If you want the Castrol/BMW fluid, you can get it in a 5 quart container from CarQuest. It's quite a bit cheaper that way, and it's enough for 2 changes. Take them the BMW part number and have them cross it in WorldPac. Last time I got some it was $39 for the 5 qt. bottle. |
