Hello,
I have read lately of the desire to use a return to a "vintage weight" for the
race cars (implied in recent letters of returning alternators or penalty lead
weight, etc)
I have a few years of crewing experience for a circle track team (Super Late
Modified tubular frame 600 HP cars) so am fully aware of the use of electronic
scales and rules at races for total weight, front to rear, left to right, and
cross weight. These weight specs are very important to the circle track
racers to help ensure some sense of parity.
Bottom line question:
Where do I find the "OFFICIAL VINTAGE RACE CAR WEIGHT SPEC" ?
Is it the production weight or some spec'd percentage of the production weight
of the car? .......Easy to find!!
Is it some average weight from a particular year(s)? .... Never seen weight
listed anywhere.
Is it the weight of the champion racer from a particular race or series back in
the 60"s? .... Again never seen weight listed.
Is this going to be another case of a different spec for each vintage race club
regarding weight or has it been decide by some national committee of vintage
race clubs?
I am not yet a vintage racer. I am slowly building a 1960 Jaguar Mk2 to run
with CVAR in Texas and Hallet.
Background:
This is a question of interest for me as the Jaguar Mk2 is not a common race
car.
With me learning to drive it will be more of a tank or rolling chicane out
there running with the Porsche 356, AH 100, and TR2, MGAs, Abarth, etc in the
Group 4 of CVAR.
I would like to understand the spec weight as I finish building this car and
not be surprised when I arrive at the track....... let me clarify... not be
embarrassed because I am probably going to show up over some spec weight :-)
The purchase of lightweight racing parts and stripping out the rear seat,
carpets, etc would seem kinda silly if I end up having to add lead weight...
but then again, as in circle track racing, this way I get the locate the weight
on the car where it will do the most good to balance the weight.
Thanks!

P.S.: When I was trying to convince my "Fanatic Racing Impaired" wife about the
need to buy an aluminum flywheel based on the weight... she suggested a diet
for me would be cheaper.... a longer discussion on moment-of-inertia did not
recover any high ground in the discussion .... initially.
