DOT approved = street legal.
Im not sure why we (you) are arguing this. Just because tire rack and Hoosier don’t recommend it for the street does not mean it’s illegal on the street. Like I said, I wouldn’t use them as street tires as there are so many better choices. I may have driven them to the gas station and back before though...
It’s nice to have choices in tires.
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!
Hi Dave, can you provide a breakdown on the 3255lb weight measurement. Fuel level, driver weight (or not), tires (R7 or PSC2s) etc. and any other factory options that may appreciably affect weight like PCCB, half cage, etc.

Hi Allan, sure.
The 3255 is Full Tank of Fuel, 2018 6speed Manual, GT3 w/ PCCB, LWB, FAL, Extended Range Tank and fire extinguisher. (No LED Lights) Oem Wheels, with Hoosier OEM Sized tires, that weigh approximately 1lb heavier than comparable MPSC2's.
No Driver, and No cage or Rollbar in the car. The car weighed 3100 even with about an 1/8th of a tank of fuel at a previous weigh in.
Thanks Dave! Great info. I've been thinking a 991 GT3 would be a fun car for re-setting TT2 records in Texas especially given the lap time you set relative to your ST3 car without A7s and limited setup time. I'm estimating your body weight with gear to be ~200lbs, let me know if that sounds about right. I also think a .1 would be a better fit than a .2 as I'd likely have to run restrictors on the .2 to bring the whp down anyway. For weight adjustments it sounds like I could easily manage with fuel load, especially with the larger tank option.

Absolutely on the same page... And I did 'think' TT2 could still happen with the .2 but you'd have to add about 100+ lbs to the nose (or so).
A good friend races a .1 in TT2 very competitively, with not too much done to it... so out of the box, and A7's... these cars would be great for that class.
Great thread, and timely for me. Can you characterize the wear you got on these tires and on these alignment? My MPSC's wear out the edges on the front with stock settings. Will likely eventually go to Hoosiers with the camber settings you have.
Anyone know what size Hoosier would fit the OE size rear wheels on a GT4? The wheel size is 11 x 20. Would the 305 fit right? The OE tires are 295.
Yes, I think the 305 would be the perfect size for the 11" wheel, as it's a bit smaller than the Michelin 305. If you're local (AZ) I have a new pair of the 305's available.

I've only done one weekend on them so far... so other than 'wear across the tire' was great that weekend, I only have 4 sessions on the tires so far. I'll have the car back on the track in October and can report back. No amount of camber will save the outside edges on the MPSC2's.

25 track sessions around 20min each?
LOL...yeah 25, 20 minute sessions seems to be a stretch. I'd say more like 12 to 16 20 minute sessions are probably more realistic, depending on your driving style.

Ack, not what I wanted to hear re MPSC's. Will await your further adventures with the Hoosiers. Thanks!
I'm fairly certain the sidewalls of Cup2s are made of spandex...
Which in some regard makes sense... as the tires were as light or lighter than the Hoosiers! Which is shocking to say the least. Typically Hoosiers are a considerable amount lighter than equivalent 'street tires'.
Just as an FYI, I've been in contact with Hoosier re choosing which 20" sizes will be manufactured in A compound. Unfortunately that decision has been delayed- originally they had planned to choose in July, but no joy yet as of now. So A7s are coming in 20" sizes, we just still don't know when. Just in case anyone else is waiting...
