The Touring Car Masters Series is run with technical regulations, as approved by CAMS, comprising touring cars of the pre-1976 era which have been modified in accordance with the CAMS Touring Car Masters technical regulations to maintain a similar appearance to the touring cars of the period.
The technical regulations are borne out of four key technical principles:
+ Cost reduction
+ Competitive racing
As a result, there are technical allowances for up to date passive safety equipment and sensible technical variations to allow for race schedules, replacement of obsolete components, performance restrictions, individual performance adjustments and up to date active safety components such as brakes.
