Ok so replacing my first split CV boot on my d21 and was thinking what are your thoughts on the silicone VS rubber boot?

fit manual hubs to it then you wont chew through them like there going out of fasion , also im guesing you have wound up the tortions ? if so drop the front diff down to correct cv axles and it will increase boot life ,
IMO the genuine boots last the longest ,

im running a couple of silicon boots and no issue at all they are alot more flexible than the rubber and take alot longer to perish and dry out

The reason CV boots wear out so quick (IMHO), regardless of make and texture is because they rub on themselves where they concintina (sp). When you put them on, spread the inner section a little further along the axle shaft before securing them to prevent this from happening. I have not had an issue with my CV boots since doing this many years ago.
You must reguarly keep them clean too as mud, grit and sand etc. will not help them either.

Like anything, a little bit of preventative mtce goes a long way.

We only use the universal streachy silicon boots at work be cause they last longer and easier to fit!!
And i agree totally with kiwipete about not letting them rub on themselves!

Ok so I fitted silicone universal items and moved them along the shaft a bit more.

Lets see how long they last once I re-fit the shafts.
