The wheels I'm looking at are those that are on the picture of the NSX below.



I am in the process of picking up some forged RO-JA wheels that are forged and light weight. I also have an extra set of new 225-45-17 tires from my e45 bmw. I have two questions for anyone who can help me:

1) Will lighter wheels increase performance (acceleration, etc...)?

2) Will lighter wheels increase fuel efficiency?

3) Will using 225-45-17 tires (3.4% difference in rolling circumference) throw off the electronics of the car? I'm not that concerned with the speedometer, I just want to know if it will affect the traction, abs, etc...? I don't want to buy a new set of 225-50-17 unless it is absolutely necessary

Thanks in advance for any members who can provide insight into the above!!

I know I'm a year late but:

1) yes

2) on the city yes, but only marginally

3) a total difference in tire circumference 3% or greater can cause the abs to function rather oddly, it probably wouldn't matter much if you're a careful driver, but I wouldn't personally do it because abs is pretty important in emergencies haha

A smaller diameter wheel setup will also improve your gearing and add to the peppy-ness of lighter wheels
