We don't have the schedule laid out yet. In rough terms, I can tell you this:
We will have the drivers meeting at 7:30 AM, track hot a 8 AM. We will have 4 run groups (3 TT, 1 Race) and will have our normal rotation through the groups every 25 - 30 minutes. I expect 4 sessions for each group on Saturday between 8 AM and 4 PM, with approximately an hour for lunch break. Enduro should start promptly at 4 PM (gridding around 3:30 PM). Enduro ends at 6 PM.

the rules are getting confusing... is that also going to cause a complete re-classification of cars too? I too would like to bring other cars to the track that does not have 5pts, but are you saying I cannot run in the point by group if my stock tires are like 140 or 180 thread wear, unless I have 5pts? Is the transponder use still the same?

confused...

We are trying to make it easier for people to run in some TT groups without having a 5 point harness set-up. We used to require harnesses on ALL cars in ALL run groups. We have now relaxed that requirement.

If your car is year 2000 or newer (i.e., safer), you can run in Solo & Point-by with just factory seat belts. Older cars have older belts, may not have as much crash protection, air bags, etc.

We still want you to have harnesses if you want to run in Open Passing.
If you have cranked up the power or cornering abilities (e.g., competition tires, etc) we think you ought to have 5 point harnesses in Point-by.

Transponders are required if you want timing results.

Alfa and non-Alfa classification has not changed.

Any clearer?

Terry - the question about Treadwear rating remains unanswered. If our stock cars, from the factory, come with <200 Treadwear rubber, we ARE required to run 5-pt harnesses?

Some examples of stock factory setups on cars most likely purchased for track use:

The Mitsu Evo MR comes with Yoko A13C's that have a Treadwear rating of 180.

The Lotus Elise comes with Yoko AD07's that have a Treadwear rating of 180.

The Lotus Exige comes with Yoko A048's that have a Treadwear rating of 60 (!)

Porsche GT3RS' come with Pilot Sport Cups with Treadwear rating of 60 (!)

I checked the tech inspection sheet again

Under the:

Notes and Comments

Driver Restraint
1. Cars manufactured from 2000 to the present, which have not been modified (see below), may run with the factory 3-point seat belts. Harnesses (see below), however, are highly recommended.
2. Cars manufactured prior to 2000 or cars that have been modified must have properly mounted harnesses (see below).
3. Belts/harnesses which appear old, warn or dirty are unacceptable.

Tires with treadwear less than 200 are classified as modified.

From the Tech Sheet:

Definitions
Unmodified Car – A car which has not been modified in order to increase horse power above the original/stock level and
which has street tires (see below). Modifications made to the intake system in front of the carburetor(s) or air flow
measurement device are excluded, as are modifications to the exhaust system which are made after the exhaust
manifold. Suspension adjustments are acceptable as long as they stay within the range provided by the original
manufacturer. Factory or purpose-built race cars are considered “modified”.
Street Tires – DOT tires with a wear index of 200 or higher. Tires advertised as “R-compound” or “track” tires are not
street tires.

We will have all our regular race & TT sessions PLUS the enduro from 4 to 6 PM on Saturday. We will hold enduro qualifying, by lap time, during one of our race practice sessions.
