Running Hoosier R7 s on your 350? What size?

Looking to get R7 s and assuming 295 front / 315 rear is the best combo?

I run the 315's squared on my R. If I was running stock gt350 wheels I'd probably go with the 295's square. Hit up trackdaytire.com and tell them Steve from Serpent Stangs sent you.:cheers:

Curious why you say a square setup? Both the R and 350 come with staggered setups....

Factory staggered setups always have some amount of understeer but the setup makes them more street friendly. A 315 setup on the street isn't much fun as it will tramline making for poor street manners. Any track rat will tell you the proper setup is square. I run 315 squared as well on 19x11 Forgelines with R offset.

This is highly debatable. Square has advantages and some disadvantages (as is true for any technical compromise). Depends on how much you street vs track and your driving style. I run staggered on all my track cars. My preference. YMMV

The OP was asking about R7's so street applicability is out of the equation. Some cars do require you tune the suspension to the square setup but I will say the GT350 responds nicely and is quite neutral on a square setup from what I have run and seen.

Bare in mind that R7's are typically wider than their measurements. Double, triple check what the REAL widths of the tires are. A Hoosier A7 "245" is closer to most 265 or so street tires that actually follow what 265 or 275 really is.

I am also trying to decide what tires to get. I am a Hosier fan, but they don't make the correct sizes. They do, however, offer close sizes. I checked the other manufacturers and put this analysis together.

For Hoosiers, I think I will go with 315F/325R (vs 295F/325R). Tire diameters are very close. If you get more than a little off, the electronic nannies will not work properly.

The Goodyear Eagles (from ZL1) look interesting and they are cheaper, but 3 pounds per corner heavier.

There's zero point to splitting hairs that thin. Pick the tire that will win races, not drive your sanity into bench racing mode.
