How much play is needed in driveshaft???HELP i have a strange 12 bolt with BMR TQ arm and a carbon fiber driveshaft, i have heard that since i have the 1350 yoke this shaft will not fit but it fits on mine just does not have alot of room to move front to back only about 1/2 a inch, will this work or not, i have a M6 if that matters
Re: How much play is needed in driveshaft???HELP Most driveshaft companies want one inch of freeplay in their measurements....I would keep a check on the trans seal with only 1/2 inch...especially if I had some folks in the back seat and ran over a speed bump...could push the shaft into the seal and rupture it.
Re: How much play is needed in driveshaft???HELP You need that extra play Joe so you will not damage that shaft going over a bump. The pinion angle, it there and has to be set with a pinion gauge an has to be set just right for hooking up. <img src="gr_images/icons/wink.gif" border="0">

Re: How much play is needed in driveshaft???HELP I had a new custom D/S made by Denny's. I was very upset when it came out longer than stock.
I measured exactly as instructed by their web site. I thought I did something wrong. After installing, I had 1" metal to metal and about 1/2' D/S to rubber seal. I called Denny and he explain that I had a normal reaction and that it was made and measured prefectly. BTW you only need less than an inch at ride height.

Re: How much play is needed in driveshaft???HELP No, you don't need a full inch of play. I'd say 1/2 inch would be plenty.
Think about it. If the driveshaft moves a full inch towards the tranny, then that means the rear-end and axles are moving a full inch towards the tranny, which means you probably need to replace the rubber bushings in your lower control arms, or else connect your lower control arms. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
The rear end will move in an arc around the pivot point where the LCA's are connected to the subframes, but that translates into very little front to back movement along the same axis as the tranny.

Re: How much play is needed in driveshaft???HELP Hey Lar's SS,
Thanks for posting. I got my Denny's a few weeks ago, and noticed the EXACT same thing. I hadn't called them on it, though, as I didn't *think* I would have problems, but I'm glad to know that they did build it right. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
BTW, the Denny's shaft rocks. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> I'm loving the Cartek / Dennys / Moser / ET Street combo at the strip. 6K clutch dumps, dead reliable every time.
