New rims cut my 0-60 a lot more than expected - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I'm going to guess the torque app is being a little optimistic there.

Best Mod for 0-60 seems to be to get a manual shift car..seriously high 7s for the auto vs. low 6s for the manual and they have the audacity to charge more for the auto??

I agree. They need to add launch control to the Auto and that would make manual and auto pretty close stock.

You don't think that lighter wheels can decrease 0 to 60 by 10%?

Would no wheels decrease it by 100%?

Or if you're after straight line speed just buy a different car with a better 0-60 number.....

0-60 doesn't matter when I'm coming out of a corner at 80kmh and have the tach needle pointing straight up.

I doubt OP will be exiting the corner at 80 kph on 145 width tires :P

The torque app is giving me the difference between the 2. I do not trust the 0-60 time it gives me. I trust in the difference between the 2. So even if its not running a true 7.2. It still cut .7-.8 off my time.

I meant optimistic on the second time (the 7.2).

There are tests out there measuring the acceleration impact of lighter wheels/tires using professional equipment. The difference is nowhere near that big. Often times it's barely measurable.

The wheels look good though.

The same person who put the 7 close to the 8...

Would 17x9 wheels and 245w tires really be that much lighter than OEM wheels with decent rubber?

.

^^^^THIS

Wheel diameter has a bigger impact. Lightness will benefit braking and suspension performance more than anything.

Mine came in around a pound lighter than OEM. 720Form GTF1 17x9 +35 with RE71R 245/40/17. Difference isn't big, but it's there. I can't feel a change except in steering feel and tramlining.
