NASA Legal Roll Cage Question
#21
AND BACK TO THE ORIGINAL REQUEST
from the NASA rule book
WEIGHT REDUCTION:
Weight reduction points are based on the actual vehicle minimum competition weight (with driver). Removal and lightening of non-essential parts is permitted unless stated otherwise in these rules. Modification of the OEM frame, sub-frame, and floor pan are not permitted (see
5.2.2) Removal or lightening of engine parts is permitted only as listed elsewhere in these rules:
5.2.2 Base Classification Table and Listed Base Weights
Any tube-frame, never street legal, monocoque purpose-built racecar, vehicle not approved by the DOT, TUV or Japanese government for street use, or production vehicle that does not retain the original front clip, floorpan, and sub-frame, or is converted (partially or wholly) to a tubeframe
design, that is not otherwise classed below or in Appendix C, will default to the Super Unlimited class until evaluated by the National PT Director for possible homologation into another class. Individual cars may be approved for classing or re-classing by the National PT Director using the vehicle’s actual dynamometer measured maximum chassis horsepower and torque, and the minimum competition weight of the vehicle (with driver).
No points mods:
42) Shock tower reinforcement plate (to strengthen tower shock mount location only--no bars)
43) Shock mount replacement/modification (only if already taking points for both shocks and springs)(may raise or lower mount
location up to two (2) inches if no horizontal movement.)
46) Add front strut tower bar (two attachment points—bolted in or as component of the cage)
47) Add rear strut tower bar (two attachment points—bolted in or as a component of the cage)

I think I'm going to leave that stuff in. Based on that, I could remove it but it has to add some rigidity. I am definitely going to remove all the tar sound deadening stuff.

That's an awesome time for a T3 car. I looked up the run off results from a couple weeks ago and I think the fastest T3 car ran 2:34.xx.
My second session out I ran a 2:36.6. I took passengers and played with some settings on the car the rest of the day. Looking at my data I should have a 2:34 in the car. Maybe more. We'll see.
Oh yea, this track is fast!!!

I won TTB Great Lakes Championship and Great Lakes TT Rookie of the Year.
