Car classing for the Golden Gate Lotus Club Autocross series is a combination of Lotus model, tire type and
Index. Indexing is a commonly used handicapping system for comparing times of cars whose set-up and modification are
varied. Separate year end trophies will be awarded for each class. Not all classes require an Index. Please Index your
car if it is required in your car's class.
Instructions
In order to participate in an "indexed" class you must first Index your car using this page. Select the appropriate options for
your car and press the "Index" button to get your GGLC Index for your car (Lotus Elise/Exige only). Enter your Index
into the registration page during sign-up. If you have any questions about
this page or the indexing system please contact autocross@gglotus.org
