hoosier 'A' compound or 'R' and versus v710?
this is all about autocross.
i would like to get v710's but i only have 1 more race in 2 weeks. but i heard that having tires sit over winter is never as good as starting a new set fresh at start of season. true?
also, which is more appropriate for my rx7 for autocross domination? the A or the R hoosier? 2730 lbs and 400 rwhp. i would think the A but never used hoosiers before.
which are faster? v710 or hoosier? i hear the new hoosier A6 is just as fast, if not faster, than the v710? any hard data out there? which lasts longer too? i'd do 8 events with a co-driver.
fyi...i'm not a noob. have been ax'ing for 8 years and am an instructor at my club (www.motorsportsne.com). always used v700's.

GRM just did a write up in last month's issue. They said the kuhmo's like slip angle more, whil the Hoosiers muscled the car around. They are both equal in performance in their opinion, using a Mini as a test mule if I recall correctly. but the Kuhmo's are cheaper.....

I read the Mini article too but the Mini is a "slow" fwd car Every SS, ASP, BSP etc car I've seen switch from the V710 to the A6 got slightly faster. On the other hand the V710 is still an excellent tire and very competitive, is cheaper than the Hoosier and has a longer useful life (though I still wouldn't store them over the winter).

I think the real question is have you driven on race tires before?
If not, go with the 710s they will give you some room to be a slight be rough in driving.
If you are very, very percise then maybe the Hoosier A (not the R it is a track tire, not an autocross tire). Hoosier stick great but one false move and you are off the track. The 710s will give you a chance to recover. Also, if you are running in BC (like us in the Seattle area), you will have some cold damp tracks, not a good think for hoosier. The 710s are actually very good in the cool and wet. Hoosiers would be a great july and august tire.

I have been running the 700 the last two years myself, and I loved them. I just went to 710s this year, and Wow what a difference. These tires stick and allow me to through the car around a bit.
I am not the precise driver I would like to be, so these are the right tires for me.

I ran a set of V710s at the beginning of this year. I ran 205/50-15s on stock vert wheels. I didn't have my camber plates, so the car understeered a bit. I have to say the car was PLANTED!! It was stable in the rain until I got into a LOT of standing water going down our back straight and then it was very forgiven. Unfortunately, my wife and I only got 5 days out of them before they were corded.

I think you'll see the A6 edge the V710 out at Nationals this year unless the new asphalt surface there doesn't allow the A6 to show it's slight advantage.

No experience with the A6, but I know you'd be very happy with the v710s, as for storing them in winter, if you store them inside the house, the impact would be way less... My codriver and I have gotten over a season out of the 710s and have used them in the rain with no problem. Also hoosiers are easier to flatspot and cord, so they are definitly less forgiving.

Ok, I went back a looked at the numbers between a guy I race with and myself.
We race about the same number of events and neither of us have made any major changes to our cars in the last two years.
He has been runnning VictorRacers for the last couple of years. Last year he beat me at every race except one. On average he beat me by 1.146 second a race (I was running 700s)
This year I have been running 710s and he is still running the VictorRacers (second year on these tires). I have beat him every race except for one. On average I have beat him by 1.088 seconds a race this year.
The way I figure it is that my new 710s are running 2.234 seconds faster than my 700s.
Take it for what its worth.
