For what its worth:
The Kastner 1972 GT6 runs Toyo?s and is setup at 3 degrees negative and has
been running a welded rear.
The Group 44 1972 GT6 is 2.25 negative running on Hoosiers with a posi rear
Both these cars handle well, slide well and have not ?snap rolled? on me in
years.
The comment earlier on Avons is interesting. I looked at the web site for them
and might try a set.
I run Avons on some of my other cars and they are much more predictive.
The edge of grip is much more telegraphed and the warning comes much earlier
that the tire will be letting go.
They are just expensive.
The Hoosier to me grip well - and then all of a sudden they let go. They yelp
once and then are gone.
They are harder to find the edge without going over the line.

My GT6 has a welded rear end. I get virtually all my braking done in a
straight line and then am easing on the gas almost immediately in most turns.
That pushes the rear end out and steers the car.
So, definitely the tires slip, and you can see it from the gummy rubber on them
after a run, front and rear. However, on tighter turns, at a certain point if
I push it too far, yep, the rear end just comes around. Usually you know when
it is coming, but on certain turns or perhaps when this driver is not looking
for the signs, it?s been known to happen. Generally not once they are up to
temp though.
I have heard the Hoosiers are grippier cold, and no question I need two laps at
speed to get full grip.
Thanks guys, all looks positive for the Toyos. What is this rumor I had heard a
couple of times that they stick good, but when they let go you're gone. Is this
what you are talking about Scott? I can get a little drift out of the TDs on my
GT.
Thanks for the input.

I?ve run the R888s for years; this year am running the R888Rs, which seem
slightly faster and more predictable. If you find R888s at this point they have
probably been on the shelf since 2016.
The tires wear incredibly well and are consistent.
I?ve always been tempted to try the Hoosiers, just for comparison, but what has
deterred me are camber settings. The R888s on my GT6 like about 2.5 degrees of
negative camber or more, and I?m told the bias plies only want 1 degree or less.
Thus, comparative sessions are impractical, and switching is a real commitment.
I?ve watched similar cars running on the track with the two types of tires, and
my impression of Spridgets, at least, is that on TDs there is a lot more drift
in the turns than with the radials. That said, and I am sure that there are
differences between the cars and drivers, there are top three Spridgets in VRG
on both types of tires. Of course, they have a solid axle in the rear, so the
Toyos may not be operating under ideal conditions on those cars. When I talked
to Toyo they recommended 2.5-3 degrees of negative camber (even though their
website says 1-3).
I also hear the radials last longer, though my impression of the R888s is that
after 15 heat cycles or so, they lose a little grip and lap times creep up
slightly. However, seat of the pants says that is less the case with the new
R888Rs.
No question the toyos are cheaper - $144 at tire rack, versus $183 for the TDs
at Woodman.
No recent experience with the RA1s.
Hey Guys (and any women out there?)
OK, thinking about Toyo Proxes for my GT6 next year. 205/60x13. I run Hoosier
TD S's right now and have always. looking for opinions on these options, all
three are VRG approved for my car. Also anything you can warn me about or
advice for switching from bias ply to radials? Just trying to get educated at
the moment, I see a lot of guys running these but have heard some bad
experience stories about spins from the learning curve or handling differences
R888R
R888
RA1
Thanks
