Donut Cage
ive heard alot of people on here mention these "donut cages" i assume when people say this there are talking about something similar to in the picture below?
just wondering what the benefits are of having these in the driveshaft?
cheers, Brad

Re: Donut Cage
The black one will restrain the buldge of compression under hard shaft rotation and thereby limit this rubber movement and contain a fractrure failure.(aim)
The triangular plates do sweet FA cause the donut is laready triangulated internally.

Take it as a given that if you want to take your car racing, you should have these covers to save the donuts.

Re: Donut Cage
Well ideally yes. Consider each coupling as part of a 3 link chain. If any link breaks, what have you got? No drive ! Well not exactly but you certainly wouldn't race with it. Vibrating like shit is ok to hobble home but not to race with.
Last Morgan Park meeting I went to that lasted over the week-end, one guy broke 5 donuts over 2 days and changed them all. ABSOLUTELY Ridiculous !!
Having a shroud over your couplings will minimise this problem. Just be sure that the fit around the internal circumference is close.

Re: Donut Cage
I used the part for a long time and have no problems with durability.
Re: Donut Cage

Re: Donut Cage
Are they made for all three guibos?
Re: Donut Cage
It's only really necessary to run cage on front one. Over thirty hard races I have never had a failure except a cenre coupling but that because I had an inferIor grey import part. To make it(cage) is another story. There must be a 4mm space between the cages as the engine moves and twists. To find a pipe with correct ID is impossible so you will have to machine a 10mm thick walll pipe. Then laser two plates .
If you have some one here in SA I have two sets left . Not cheap but you will save bell housing,flywheel and donut when it explodes. 250 AUD and you can collect. Easier said than done.

Re: Donut Cage
thanks for offer...don;t really know anyone there.....
Come to think of it, I only had one rear guibo go and at least three fronts...never a middle.

Re: Donut Cage
It only happened once but I had a segment break out of all three couplings AT THE SAME TIME.
Make of that what you will.
