That's pretty awesome if you're trying to figure out wheel offsets and whatnot.

I use this one when shopping for tires, if you happen to have a BMW you can scroll down and load up the gear ratios, or you can enter them manually, and figure out how much of a deviation in diameter you'll get with different tires sizes and how that will affect your gearing.

When I fucked up and put 245/40s on my car instead of 245/35s it would've theoretically done 100mph in 3rd gear. It caused about a 5% decrease in gearing so it was more like the car had a 2.97 diff instead of a 3.15.
Now: 07 Porsche Cayman S | 18 VW Tiguan

Then: 18 VW GTI Autobahn | 95 BMW M3 | 15 VW GTI SE | 12 Kia Optima SX | 2009 VW GTI | 00 BMW 540i Sport | 90 Mazda Miata | 94 Yamaha FZR600R | 1993 Suzuki GS500E | 2003 BMW 325i | 95 Saab 900S
