Slowest GT out there?

[2015 Silver GT]

The 3.15 gears and 20" wheels are working against you.

The wheels yes, the gears no. These autos have steep gearing in the transmissions making the 3.15's act more like a 3.55-3.60 depending on tire size.

Fastest I got was 5.5...but then again I didn't fully commit to it because I thought a cop was coming up behind me

And you thought he would object to you getting to 60 in a hurry? Sheesh. What fun are the cops in your area?

closer to 95-99, but yes, close.

With a heat index of about 103-112 daily.

If he was running 18 inch wheels would he be faster?

I got 5.3 today running 87 octane. Factory 20 in rims. 3.15 gears

Slightly faster due to the upsprung weight advantage of 18's over 20's. But that's it. An 18" wheel will still probably be the same overall height of one with a 20" wheel. Just with more tire.
