Just to add more fuel to the fire, has anyone seen the racing style accordion-less boots used in a street car application? Go down the list and click on the Lobro 108mm CV boot listing

http://www.taylor-race.com/items.cfm?categ...2=Boots%2C%20CV


I suspect since these type of boots are intended for open wheel formula cars, the boot doesn't allow for a lot of angularity? I don't think the lack of an accordion is a big issue since the accordions are more of a feature for a FWD-like application where the CV actually pivots?

Never seen them on a non-open wheel.

This isn't directly applicable since I've never used the 108mm models, but I haven't been pleased with the longevity of the smaller ones on a few open wheeled race cars. The centers tend to tear pretty easily, even on a car with low shaft angularity. We actually went to bellowed ATV boots for greater reliability at lower cost.

Edit: Meant to add: All of the other Taylor Race stuff is great (as is their customer service)-and Scotty is the man! (IMG:style_emoticons/default/biggrin.gif)

Thanks for sharing your personal experience with the bellow-less boots. I suspect I happened to stumble across them by doing a google search. Didn't want to give them a blind try for $55 each! (IMG:style_emoticons/default/laugh.gif)

I thought I'd follow up on my own question for any future readers. I had some new CV bolts from PMB. With the flange and gasket in place the length was fine using the newer/thinner CV's. Not sure if the bolts would have been long enough for the older/fatter CV's.

Also, I got confirmation from a local Porsche shop that the float compensates for the difference in the CV's and that it shouldn't be an issue.

here's some gratuitous axle porn...

Just checked my stock, no strap even, just the rubber boot.

Mark, is that the boot your running on your car>?
The reason i ask is that i ordered boots twice from AZ autohaus and got the wrong one.
maybe that makes me stupid but Im just trying to find the right boot so i can get my rear axle situation sorted out.
Or could you guys tell me what the diameter of the flange where the boot hits it.
mine is 2.55 inches od on the flange. every boot i get fits inside of the flange and thats wrong.

It looks like swayaway is un reachable...

But this website seems to sell the correct axles :

So I’m a new to all things 914 and looking go 5 stud.
I’ve read both threads 2 or 3 times, brilliant work.
I have front and rear 5 lug suspension from a ‘78/‘79 911sc so its an easy swap over except for rear.
So I’m thinking why not just make up a 28mm steel spacer that will fit between the gearbox flange and the 911 axel?
Obviously one end will be drilled for the 100mm 911 CV and the 108mm flange with countersunk bolts?
Any reason why that wouldn’t work?
