Technical regulation
1st preface
prohibition are all changes, which not expressly in the following regulation the triumph & British GT Competition
are permitted. Permitted changes may not involve bad changes. In cases of doubt the participant in the accountability
stands regarding the vehicle parts in question. With Homologated vehicles the participant a copy of the appropriate
Homologations sheetes, which must be authenticated by a ASN, must with which technical acceptance submits. For vehicles
without FIA Homologation the participant must submit a comprehensive catalog and/or manufacturer documents. On the
acceptance of such documents the responsible technical commissioner decides. The components of the vehicle must keep
