Fastest as in speed? Or quickest to say 60 mph or 1/4 mile?
3.55's will get you quicker acceleration at the expense of mileage and top speed. I ordered the 3.55's w/ the automatic.
Remember that is the "old" model on SLA. I think we will see a difference with IRS. I'd even take you up on a friendly race if we were closer. Mine will even have a little extra weight with some options I chose. Besides, 3.55's weren't offered on automatics from 11-14 were they? Correct me if I'm wrong. If you like extra step off the line, don't mind worse mileage and will hit your local dragstrip a few times, I'd recommend the 3.55's.
Regardless of wheel size all 2015 Mustang tire diameters are 27".
Id happily take that wager my friend! I am interested to see how this IRS stacks up to the old yet proven SRA. Also, the gearing is the same on the auto as It was previously, so the rear end gear choices should replicate the same performance. Its a matter of traction and wheel hop issues at this point given the new rear end architecture.Remember that is the "old" model on SLA. I think we will see a difference with IRS.

Although I suppose I should be talking it down to secure my combo as the "quickest". ;)
I agree, it will likely hold its own. The base GT gets dinky 235 width all season tires, which certainly aren't going to help it. At least the PP adds much wider, stickier rubber. The new launch control feature will help the manual with traction/launch consistency as well, compared to the previous gen.I would tend to agree with you. Although a base manual GT with PP only and the 3.73 gears might be right there.
Yup that's why new wheels and rubber will be the first order of business for me.
See last quote below, the 18's wheel and tire is likely lighter than the 19's & 20's. It will suffer having 235 width vs. either 265 (20's) or 275 (19's in PP). Still very nominal differences.
My local is an 1/8 mile as well. Let us know.
Would be fun to get together. We are quite a distance from each other though. Open invitation.
Another reason I chose the 20 inch wheels. 265 width vs. 235 width albeit at a slightly greater weight and rotational inertia. Its also why I chose the 3.55 gears to offset the heavier 20 inch stock wheel/tire combo.
What he said.
