That's the post I was thinking of, where's that post? Obviously different rims and also tires are going to vary (all 20 inch rims don't weight the same nor do all tires), but I don't know of any 20 inch rim and tire that weighs less than a 17 inchbullit with the same diameter tire.

i put down 259 stock with 17's. 270 is a longshot for stock, highly unlikely. I usually see anywhere between 255 and 265.

And so the debate goes......Everybody knows 20's rob power but 259 HP is not bad at all for a stock GT. Happy B-day and great numbers on the dyno.

your right, but not as much as some think. About 5-8rwhp with 20's compared to 17's
