CV Boots Suck

CV Boots Suck
I posted this in the other 944 specific forum, but would like to hear from racers.
Does anyone know of another solution for these dreaded CV boots? Does someone make a boot that is thicker or more substantial? I swear I have to change out these things about every other race weekend and I'm getting sick of cleaning up the greasy mess it creates when they get a hole in them or worse yet, tear apart completely. Not to mention the PITA it is to swap these things out at the track when you have limited time. This weekend was the last straw.... The entire boot tore all the way around where it attaches to the collar against the CV joint itself. WTF? These off road race guys must have some sort of solution...?
I think I need to develop some sort of shroud to protect the boots from debris and help contain the flying grease if they do let go.....
Any input would be greatly appreciated. Thanks!

I read your post on the 944 forum about bloating of the boots.
The standard grease that comes with axles is not really suitable for racing. It overheats and basically turns to liquid. The boots the are supplying now do suck. You can try venting the boot by placing a small plastic tube under the cv boot, like the ones the come with spray aerosols like brake cleaner. I would use a zip tie and not a hose clamp like in the pic. Changing the grease to something like redline or neo will help with cv joint longevity.

You might try "aero boots" if they make them in the right size for you:

I use NEO in my CVs.

Some folks will put a second boot on when they rebuild the joint and tape/tie it down in the middle of the shaft. Then if one dies, they can cut if off and then move the new on in place without having to take the shaft out, pull the joint apart, etc.

Also, check the angle your axles have into the CV joint. Very low cars consume a lot of CV boots because of the flex that the boot experiences as the wheel turns.

You can also install "aero boots".

Yes my car is pretty low, but my axles are not at a bad angle. I don't hit curbs or go off track. One of the problems with the tracks out here is the rocks and debris that get flung on the track surface from "other cars". I think that's to main cause, although this last weekend the boot was torn all the way around....

I use the proper band clamps that come with the boots/axle. I have the special pliers that crimp the band on correctly.

Which boots are you using?
This may not be relevant, but my friends in the repair business have sworn off all CV boots that do not come from the dealer. They've tried every aftermarket "OEM" labelled CV boot with horrible results. The only ones worth buying are dealer supplied.

I bet its the driver side CV that failed (s), which is right next to your exhaust. Is the pipe wrapped in a heat shield? I loose a boot every now and again, some last, some don't, so am forced to carry spares. What a mess.... Exhaust heat shield, vent tubes and Redline grease help for sure, but you should get a season from them.
