GTF1 17x9 = 16.8 lbs.
OEM Michelins = 21.5 lbs.
245/40/17 DW = 21.3 lbs.
You mentioned you switched over from 5 Zigen wheels (already lighter than stock)...
could you tell a difference in the weight reduction over the stock setup? |
The 720Form site says they're 16.5 lbs. My 5Zigens (17x8 +48 FN01R-C) were 16.7 lbs. when I weighed them, but I'm pretty sure that was before powdercoating (it's been a while), so that adds a small amount extra.
Since I broke two of the 5Zigens, I had been rolling on the stock wheels/tires for a month or so and yes, I noticed a difference in acceleration right away. At first I thought it was just the cold air, but it's consistent. They're only a smidge lighter than the 5Zigens, and I didn't run them back-to-back, so I can't really compare those two except to reiterate that the 245 feels much better on a 9" vs. 8" wide wheel.
