310mm front discs with early boxster calipers?

[-Alex-]

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.
