Interesting post... I would also like to know.
I agree w/ you. If you're not able to establish a baseline before you put on the 18" wheels, you really can't tell, as so many of us on here have obtained MPG's that vary quite a bit from one another.I will be switching to a much lighter wheel (holding out on revealing the specs) once I receive my car, but I will not be running a stock tire since my wheels are 18". This will throw off the mileage slightly, but I'll gladly report my findings. I was thinking about running with the stock set up for a month to get some data first to compare... but I'm too anxious to get the modding under way. The car will need a break in period anyhow... so my comparison probably won't be truly relevant until next year.
Damn, I was afraid someone would say something like this. Now I won't be satisfied with the stockers (even though I think they look nice).I was the one who posted that pic.
And I am on a 15 lbs Volk Racing TE37 now.
Much better everything. Steering quickness, steering response, EV initial start, Fuel efficiency went from 5.2L/100km to 4.7L/100km immediately.
The dampers definitely have sped up too.
They're not cheap, but they sure are sexy . Besides, with the amount you'll save on gas... they'll pay themself off eventually lol.Thanks for the info. Team Lexus. With 15 lb. wheels, you're paying a big premium up front if people go that route just to get better MPG's and to save on gas. I know you got a good deal on yours, but Volk's aren't cheap!!!
Assuming a constant price of $3.80/gal., those rims will pay for themselves at around 118,421 miles!They're not cheap, but they sure are sexy . Besides, with the amount you'll save on gas... they'll pay themself off eventually lol.
