310mm front discs with early boxster calipers?

[-Alex-]

Is it possible to fit 310mm front discs with boxster calipers, that came with kerscher set? Far is i know, early boxsters did have 298x24 discs at front. Ok, maybe 298mm discs are enough. Rear i will have 944 turbo discs with 944t or boxster calipers.

I have been planning to replace kerscher vented discs with custom made aluminum hubs, wilwood aluminum rotor hats and wilwood curved or directional vane rotors.

Already have those hats with 8x7" pcd and designed aluminum hubs

Why do you want to get a 310mm disc instead of a 298/299mm dics?
Though it shouldn't be a problem, obviously you'd have to space the caliper a little further outwards radially.

the boxster calipers that come with the kerscher kit are boxster 2.7 rear calipers iirc suitable for a 20mm thick disc

I'v been studying and no, according to the numbers, kerscher brake kit has non-s boxster front calipers, which are originally used with 299x24 rotors.

Rears on early non-s boxster are 292x20, and use different caliper at the rear

Also found that watercooled audi/vw guys use this caliper up to 312mm discs from A8/TT. So 310mm rotors should not be a problem.

You will probably have to use at least 17" rims to clear the calipers on a 310/312mm disc.

lol you;re right - i didnt remember correctly!

i jst checked my emails from when i spoke to them and it is indeed a front caliper designed for the 24mm thick porsche disc but used on a 20 mm thick vented disc for a bug!

i'l shut up now

Yes i think that i may need 17" rims. I have a 15" 944 space saver alu for spare that fits with 944 Turbo rearbrakes what i have now at the back (299 rotors, 4-piston brembos).


I was hoping to use the space saver on the all around if needed in emergency. But probably it wont fit anymore with 310mm rotors and boxster calipers, but maybe with 20-40mm spacer?


Allthought Kerscher said that their brake kit with 278 rotors and boxster calipers its possible to use any 15" beetle wheel. With 310 rotors, caliper will be pushed out 16mm.

So, there is two choices, if spare wheel doesnt with: 1. 20-40mm wide spacer 2. Smaller rotor (300-304mm)
