Autocross classes and prep at LOG autocrosses

Unlike other marque clubs, Lotus LTD does not have a rule book. The rules are different at each LOG.

I think we can fix that. We don't need anything more complicated than the rules at previous LOGs, we just need some consistency.

We could start by listing the rules for each of the last ten years and combining the best parts of each.

Who wants to help?

Why not just follow SCCA rules / classes?

Very good question.

Traditionally, marque clubs like PCA and VTR have their own classes for cars. You can come up with their national rules set fairly easily in the Internet age.

Since it seems Lotus LTD has not codified rules for autocross, each LOG has been different. These individual-event rules don't usually seem to get a lot of exposure pre-event.

OK, so your plan would be to use the SCCA rules set. This makes some sense at the LOG33 event, since we will be running together with an SCCA Region at one of its scheduled events.

Normally what happens (at least I think it's normal, the only one like this I have attended was 2005 in Saint Louis and that one had been planned as our own event, but GM pulled the site and we wound up with SCCA at Gateway) is that the SCCA gives the LOG autocross chair a list of run times for the Lotus entries and lets him sort it out into LOG classes.

All the Super Seven cars and clones would run E Modified or D Modified.

7 & 7A [note that this does not include Super Seven cars]
Eclat
Elan (RWD)
Elan +2
Elite (1216cc)
Elite 2+2
Esprit (non-turbo)
Europa
could run C Stock, if you can actually find any that meet Stock rules.

Stock atmospheric Elise/Exige cars would be Super Stock. Lotus 7 & 7A (948, 997, & 1098cc) could run D Prepared.

Stock boosted Elise/Exige cars would be Super Street Prepared, along with the M100 Elan.

I don't have time right now to find all the Lotus cars in the SCCA book, but it is at:

The Road Tire can of worms is at:

=============

As an alternative to straight-SCCA classing, here is my first-pass attempt at our own classification. Modification limits are fuzzy, as they have been at every LOG I have attended. Your SCCA idea could fix that.

=============
Tires are the biggest differentiators of autocross performance. The tire split for street-able cars will be the same place as used by SCCA.
"Street" tires will be a treadwear rating of 140 or greater. (140+)
All DOT tires with treadwear ratings below 140 will be considered DOT sticky tires. (<140)


Lotus 7 and Replicas, 140+ tires.

Lotus 7 and 7 Replicas and all Lotus race-prep cars. 140+, <140 or racing tires. All cars with non-DOT tires run in this class.

Street-able Elan (Early) and Europa and Elite early. 140+ tires.

Street-able Elan (early) and Europa and Elite early. <140 tires.

Street-able Esprit (atmospheric) and Eclat and Elite (late) and Plus 2. 140+ tires.

Street-able Esprit (atmospheric) and Eclat and Elite (late) and Plus 2. <140 tires.

Street-able Esprit Turbo and Esprit V8 and Evora. 140+ tires.

Street-able Esprit Turbo and Esprit V8 and Evora. <140 tires.

Elise and Exige atmospheric. 140+ tires.

Elise and Exige atmospheric. <140 tires.

Elise and Exige boosted. 140+ tires.

Elise and Exige boosted. 140+ tires.
