Recommendations:
Camshafts & Followers:
We're seeing a high percentage of S54's with worn/flat Followers as well as Camshaft scratches
Therefore, we recommend you take full advantage of the FREE OF CHARGE LABOUR to have new Camshafts & Followers installed to give maximum longevity to your S54 top end.
This can be, Schrick, BMW, Turner, CAT, etc.
From OEM specs, to CSL specs, to race specs, this can enhance your driving experience.
It's not a mandatory option, and therefore only a recommendation.
"Pay for the Camshafts & Followers and we'll install them for free".

PLEASE NOTE:
We're finding some E46 M3's with extremely dirty/stained/clogged/tarnished Cylinder Heads (due to incorrect oil grade, poor oil quality, or extended service intervals).
Some vehicles require the Cylinder Head to be chemically cleaned in a Hot Wash bath twice (or even three times).
Optional Extra:
We are also able to thoroughly clean the Rocker Cover in the Hot Wash tank.
(Some vehicle need this, and some don't. We can advise once we've removed the Cover).
To make a booking for this service we require a £500 deposit.
