THANK YOU ALAN! I'll just hope you aren't my Service Adviser when I go in for warranty work.
NO ONE is saying HOOSIER's should be driven on the street.. they are a TRACK tire... but they are NOT A SLICK Racing tire. Those are completely different, deliver considerably higher load forces and frankly weigh almost 1/2 as much as a 'DOT Competition Tire'.
To try and get us back on track... here's the latest alignment settings, getting ready for this weekends event... I'm extremely pleased with how much Camber we were able to get out of the front, just with shims and not modifying anything, or replacing any hardware. I'll look to provide updates following this weekend!
Car was weighed/aligned with a full tank of Fuel.
Best Regards,

So much goodness in this thread!
I will try to start my R7 a bit higher PSI and try to manage PSI by over driving them less at higher PSI towards the middle of the session.
This based on some suggestions that my tires overheat, based on starting too low +/- 20PSI and then needing 3 laps to get them to 28.
After that they are cooked quickly and go slow, even still going to 35 in the end.
Maybe starting higher resulting in 35+PSI hot by starting at about 25PSI will keep the temp down a bit longer?
Sure wish we had temp indication a la BMW.
So, I got a call from TireRack this morning. Evidently Hoosier has decided "the 335 size tire is not as wide as it should be" and that "they are going to make them wider". I asked how much wider and it wasn't known. It is supposed to still fit on a 12 inch wheel. The current size is no longer available and the new wider tires should be in stock around the end of the month. I was told they would be measured when they arrive. I learned this from their work on trying to fill an order I placed on July 30th. On the good side, the new tire will cost about $31 less.
Interesting comment on the 335/25 tire size... agreed... today it's the size of our '305/30'... so I hope they 'stamp' the new ones 305's... and move the 305 to a 295 size... which is more indicative to what I measured when I ordered them.
I'll try to get some time to reach out to Hoosier in the next week to get an update.

It sounds like Hoosier will make the 335/25 wider, which is good for the 335/25 folks, but not do anything to the 305/30, which is no good since it will still be narrower than the MPSC 305/30? Hope that they do move the current 305 to 295, make the 335 wider, but also make a "true" 305/30.
I ordered set of. Hooosiers from Trackdaytire.com they hav 335/25/20 narrow in stock as does the Hoosier warehouse in Manchester CT ,Hoosier will now be making a wide and narrow size 335 one that will be a true to size and the other will be a 305

I sent an email to my contact at Hoosier, and should have an update by Monday. Ironically... I think the 305 is closer to a 285... and had though on the 'RS' with the 9.5" front... it could be the perfect FRONT tire!
And then will look to learn about what the plan is with the wider 335 and what they may do with the 'current' 335 mold.
I guarantee you if R7s are on a car at-fault in a serious accident on the street "the eyes of the law and the lawyers" will see it differently than you do.
I don’t just play a lawyer on tv but I am one in real life to.
HoosierR7s are DOT legal. The fact you can use them on the street doesn’t mean you should. In fact the argument of negligence would be very easy if an at fault vehicle had them on and tire failure was part of the reason for the accident. Tread thickness and sidewall strength is just not the same as a tire designed for street use. It would just be In my opinion at least beyond stupid to use an R7 or A7 for the street.
Anyway I run A7s as I find that although they don’t have as many cycles in them as R7s they don’t fall off as precipitously as they wear.
Ok, got the latest low down on what's happening in the 20" Hoosier Tire Sizes:
The Wider Versions are coming next month – September – hopefully. A Product Bulletin will be coming out, to outline the different sizes and dimensions. The new specs are below. However, as soon as the “N”arrow tires are sold out, Hoosier does not plan on making any more. There is talk about relabeling the "N"arrow P305/30ZR-20 to a P295/30ZR-20 but that is down the road a bit.
I have a solid production date on the Wider P305-20 R7(Friday, Sept. 7) but still waiting for a solid production date on the Wider P335/25ZR-20 R7.
So, the good news, from the way I read this... the 'Narrow' 335 is going to become the 'Wide' 305... which is perfect for our cars.
And seeing the even larger 'Wide' 335 coming... not only may be a good alternative for the RS, it may work for those who've built track wheels slightly wider than the OEM 20x12. However, for the RS, I'd still have liked to see an 1" more in diameter to help with the offset.
Looks like the 'Narrow' 305 (really closer to a 295) will be going away... but could return labeled as a 295... which may work on the front of an RS. I have a pair still... so may try fitting them when my RS gets here in January.
