Second only to flogging the living daylights out of our rides, we hoons love to scheme. For every hour spent under the car in the driveway, there are 8 more spend BSing on forums, browsing through catalogs and generally fussing about what we’re gonna do with the Country Sedan Falcon Uberbird Wrangler WRX Trailer latest project car.
For hoons in the know, gearing is the killer app. Without the proper mix of tire size, rearend and transmission gearing, you’ll be bogging your puny 260ci or revving the hell out of your 390. Oddly enough, salvation comes at the hands of a sub-page on the long-dormant Vexer.com. You put in your transmission, rear-end and tire size, and it does the rest, complete with the spiffy visual readout you see above. Sure, you could do the same with a spreadsheet, but it wouldn’t be as cool. Check it out at Vexer.com.

  1. My day is shot.
    Thanks, really. I do mean it. I am sick of doing the math on paper for people then they try to argue it. This is easy, "here, look at the pretty dials damn it."

  2. Huh, my car is geared for 200mph at 5030 rpm and 60 in reverse at 5300. Seriously 200mph gearing? I drive a 3.4L Impala. Explains the awesome highway mileage though.

  3. This is pretty cool. My car is good to 200 mph in 2nd gear, apparently. Of course, I'll be spinning 15,000 rpm. I can't wait to get that F1 engine!

  4. This just helps me with arguments I've had with people because they do not believe that I've taken my car to a certain speed with my 3.73 gears…
