Steve...
I remember well when your Dad de tuned the car for 'vintage'. The thing I
remember most is how much those Bulbous orange (Signal Red) Fenders weighed due
to all of the bondo repairs. I could hardly lift them. I thought to myself,
any advantaged picked up from wide wheels and slicks...gets tempored by the
added weight.

My TR3 had wide slicks in the SCCA days, now I run 5.5 wide rims with the best
rubber Legal in my vintage club. The car handles great and is very
controllable. Also, the tires are less money than the treaded Hoosiers.

I totally agree with Glen and Tony here. The skinny, hard Dunlops would be
great if it were the spec tire for all production classes.
Sadly, the technological genie is out of the bottle, and once that happens,
putting him (or her) back in that bottle is essentially impossible.
The mindset of vintage racers is a bit different than SCCA or IMSA, but, I have
the feeling that the hard chargers will still push those old skinny skins
beyond their limits, and spins would prevail, which are certain to cause more
bent sheet metal than currently is the case, and vintage racing intends, in
large part, to keep both drivers and cars in one piece and looking pretty much
as they did before racing commenced. But, this is not a new subject, and as
for originality and the "old days," I do remember walking into a Triumph shop
in New England in 1970 that ran an SCCA TR4A IRS, and it was wearing big, fat
cheater slicks....
The larger question of when a safety improvement is a performance improvement
in disguise is not one that's going to be resolved simply or easily.
Generally, bits that don't break unexpectedly are a safety enhancement, as Tony
makes clear. We don't think about safety in the same way as in 1962, because
we know a lot more about it, especially from the experience of others. No one
gets too excited about helmet restraints, because we know a lot more today
about TBI and its causes than we did then, for example. We could get quite
priggish about originality, but, would anyone today say that the stock fuel
tanks were just fine and fuel cells are an unnecessary expense, knowing what we
know about fires, or that four-point roll cages aren't original, and therefore
shouldn't be allowed (even though there's clearly a performance advantage to
them in stiffening the chassis, if done cleverly)?
But, one thing that everyone so far is unwilling to admit is that we are
inveterate tinkerers, and saying, "well, this little piece of shit part that
fails every Friday like it had a timer built into it was good enough for the
factory in 1962, so it's good enough for me" just isn't in the vocabulary of
most of us. Kas must have file cabinets full of dynamometer test results as
proof of that. In that regard, the rules always have some rubber built into
them, whether it's apparent to all or not. No one goes into this hobby with
the belief that a DNF every weekend is great fun.
Cheers.
