2017+ SS 1LE M6 Gear Ratios and Max Speed per Gear

Just got my 1LE last week, anxiously awaiting break-in and start of track season in the Northeast, so doing some couch racing/performance data collection.

I didn't find it posted anywhere here, so posting it for my own info, and maybe to help others.

Can someone double check that the data is correct? Do the top speeds/gear at redline match real world?

6th Gen SS and 1LE M6 Final Drive: 3.73

6th Gen SS and SS-1LE Tremec TR6060 M6 Gear Ratios (overall):
1st - 2.66 (9.92)
2nd - 1.78 (6.64)
3rd -1.3 (4.85)
4th - 1.0 (3.73)
5th - 0.74 (2.76)
6th - 0.5 (1.87)

Max theoretical speed/gear (MPH) with SS 275/35R20 rear tires (27.6in diameter):
1st - 53
2nd - 80
3rd - 110
4th - 143

5th - 193
6th - 286

For 1LE rear tire 305/30R20 (27.2 in diameter), corrected -˜1.4%:
1st - 52
2nd - 79
3rd - 108
4th - 141

5th - 190
6th - 282
