hello so as im reading thru many posts on aftermarket wheels everyone seems to have the same results, a droop in mpg. i know there are many lightweight aftermarket wheels out there so is it the fact that by going with a larger diameter wheel the actual rotating mass is being moved further away from the hub? secondly there are many people using different offsets on wheels, i was just wondering what the best offset for say a 17" wheel would be, or does it depend on the wheel itself? as for springs i am wondering if there is a list of different springs and how much drop they each have? are there major ride quality differences between different spring manufacturers? how are the trd springs? thank you in advanced for any input/advice
To minimize the mpg hit go with the lightest ones you can afford and keep the offset between 45mm and 50mm. The OE 17" has a 50mm offset. This is not cool for the hellaflush crowd but it keeps the wheel and tire from sticking out into the airstream and beyond the wheel spats. Regardless, expect a hit.
