SCSS Regulations

SCSS Kart Classes

Unlike many other circuits, we are proud to be inclusive at Leicester Karting and cater for a variety of owner-driver kart classes. Listed below are the classes which are eligible to race in the Stretton Circuit Sprint Series (SCSS).

The information below sets out the broad basis for entry into the series, but we are happy to include any other karts that happen to fall outside of this framework. We aim to run as close to MSA/ABKC regulations as possible with regard to the technical regulations, but we also aim to strip out some of the more trivial regulations in order to make the series as accessible as possible.

Conduct Standards
The SCSS is built on integrity, respect and the conduct of our members.

• All drivers, mechanics, parents and affiliates are expected to conduct themselves to professional and respectful standards at all times.

• Any issues/disputes must initially be brought to the clerk of the course (Ant Durham) which will then be brought to the attention of Stretton officials if necessary.

• Any aggressive or disrespectful behaviour towards any member of staff or driver/affiliates may result in exclusion from the current round with no refund.

• Karting should be fun for everyone involved and we intend to keep it that way.
