BEST street/autocross performance tire in 285/35/19 for Brembo/Track Pack wheels?
a 9" rim is too narrow for a 285. You'll need at least a 9.5" wheel to support it. I have 9" fronts now with 285's and turn-in is sluggish at high stress/high speeds. I'm going to a 9.5" front in a week in large part because of this. That 1/2" makes a big difference on the 285's on our Mustangs.
Others have seemingly had good luck with RA-11s and M/T Street Comp on 9" wheels.
I run Toyo 888's front and back (the backs are 315's on 20x11's). Mine are 20's though, so I don't know if the 888's come in a 285 for a 19" wheel.
I agree that this is a preferable solution but at the moment, not an option for me... I'm dumping most of my expendable budget into my Mopar these days. Per your suggestion, I did call Tirerack. They're apparently not going to take a chance and deviate from common wisdom (ie 285 not reccommended for 9" wheel)...and the conversation was very robotic. Thanks...this is what I'd assume they would say. There are lots of folks running 285 RA-11s though...and again, while not ideal, it seems that they still work well. Bridgestone won't reccomend it either. I agree that they're fine...but they're half an inch taller than stock. I don't know about you but I paid extra money to change to a 3.55 axle when I ordered my car (should have gone 3.73) so they're not the choice for me since these tires would take me in the wrong direction.
Not sure if there is a difference for doing auto cross vs road use from a legal standpoint.
I was just wondering if Ford offers the track pack wheels in a wider width like 10" that would us set up our cars staggered and allow for the wider tires? It would be great to have the matching wheels and a staggered stance.
The trick is finding out where the truly competitive Mustang AutoX guys hang out online (not being coy here, I honestly can't tell you this), then ask your question there.
For a road racing street tire, you're not going to beat the Toyo Proxes 888. I don't autocross so I don't know if they allow slicks, but I'd be surprised to hear of a better road course or turning STREET tire for the Mustang.
Well...I'm starting to rethink my priorities and the Michelin Pilot Supersports are available in the stock 255/40/19 size...
Do you think they'll be better than the stockers?
Almost everyone seems to go with the 275/40s so it's hard to find opinions on the 255s.

I'd probably do the 275/40s and run 1" spacers front and rear. The Brembo wheels look good when they're pushed out to the fenders.
Yes. Pilot SS are the best tire in this category.
