There are a few of us that prefer the "R" tire allowance. If I remember
correctly, there *is* a few ST classes. ST does still mean "Street Tire," yes?
Please enough of the "get rid of "R" tires" soap box. You'll have to pry my
Hoosier Racing Tires from my cold dead hands (or rims). :^)

With Danny Shields' recent articles about this and several postings touching
on this subject along with high speeds being obtained by high performance
stock cars (like SS), it is now high time to propose the removal of DOT R
Tires (called "cheater slicks") from the stock classes. There are many
arguments in favor of this but several readily come to mind: 1. The
technology of
stock cars and street tires is advancing and DOT slicks are no longer
needed. 2.
The stock class will come closer to being truly "stock" by one step and help
the newbies. I am sure others on this list can add to this. Two other stock
allowances should be considered for removal: 1. Cat back exhaust - the new
exhausts are better. 2. Any air filter - again better stock technology. The
only one that I would keep is the shock absorber allowance but I would cost
restrict these - if this is even possible. Time to make stock more "stock"
and
still have lots of fun. Jim
One data point on an admittedly unusual car, the Elise. On a given one
minute course, the stock street R compound tires are only roughly a second
or so
slower than a Hoosier shod car. You can drive the Yokohama A048s about
8,000
miles on the street and for about the first 5,000 they will be gummy. They
are fine on the street durability and rain wise as long as it's above 45-50
degrees or so. With the full street tires, the Yokohama Advan Neova AD07s
about one more second is lost. Now the differences will change with course
and
car but there are many real street tires that drive just fine for autocross.
