    obviously confirm measurements with tape measure.
    Oh I see now - cool!

    So that would be a 1.56" (0.78" x 2) drop, Leaving me with 2.32" of required width.Going from a 215 to a 245 = 30mm (15mm per side, assuming identical centerlines) so that's 1.18". So I'd need a 1.14" of extra track width (assuming drop springs are not available).

    Unless my math is totally fucked.
    Yeah, math is only a little fukt. Can't use 2x radius.

    Only a single radius can be factored in because the only measurement that will make a difference in ride height is ground to hub. Creating more space in your upper wheel well won't affect ride height.

    Also, 1010tires is showing radius for 215/50/17 as 12.73".

    My old Tesla Roadster ran out of poop at 182 kph. Model S has a lot more power. I did ~215 kph in my old one and it was still accelerating. Haven't tried a drag strip with the new one, but the claimed top speed is 250 kph.

    Just curious. More gearing is better.

    From what I have found online specifically Bolt related, smaller overall diameter wheels and tires as well as lighter weight = better power to the ground.

    Maybe that's better for all cars, I've never done much research in this area. But given I never have to 'change gears' and the top speed of Auto-x isn't crazy high, I'd think getting to high speed (even if the maximum is lowered) is optimal?

    I've been saying it since my first post...

    Slightly smaller wheels won't kill your contact patch and Lot 9 isn't THAT rough.... A shorter/lighter wheel package will improve acceleratio, braking, and road feel in a big way.

    This is even more critical since the Bolt is current limited to 50km/h... So it has constant torque from 0-50km/h. HP is basically torque*rpm, so if your wheels are turning faster, the car is doing more work.

    Lower weight and diameter is easier on the driveline too.

    You still need to buy tires for those 13's I sold you and bring them back to an event.
