997.1 Caliper Dust Boots/Seals - What Size?
 

I need to replace the dust boots in my calipers as track days have resulted in mine cracking/falling apart in a relatively short space of time. Can anyone tell me what sizes I need? In the Porsche Parts Catalogue there are two pages for fronts, each with different sizes listed. I know the I450 option denotes PCCB, which mine is not, but there's still two sets to choose from?

If you do a lot of track days and don't drive in the rain or snow/salt, I would not bother. You'll burn them off again in a couple track days.

I'll put silicon boots in this time as to avoid the same issue recurring.

We don't salt the roads here (doesn't get that cold in Auckland, NZ), but I do drive in the rain and don't want to have to rebuild my calipers on a regular basis.

Anyone?? Would really appreciate a steer in the right direction. I guess worst case scenario I order 32mm and 38mm and just see what fits...

If you find suitable high-temp replacements, please let us know!

Reviving my own thread, in the hopes that someone who knows or has done this before can tell me what size the front calipers need. Anyone ordered or fitted new dust boots before?
