[racing] IRS Conversion

Hi Gordan et all,

It’s worse than that. The early XJ40 rear brakes (11in solid discs) have
no problem with stopping power, but with longevity under race conditions
when on the back of an XJS.

I can see that, but can you venture a guess about simple everyday traffic?

(snip)

Later XJ40 type brakes (11.5in solid discs), however, seem to be fine.
But for preference, go for the 12in X300 vented discs. You can never
have too much brakes.

One detail I wondered about: the fulcrum bearings are a different
size on the '40. Which ones did you use and did you modify anything
there?

cheers,–
Arnoud
