looking for some wheels for next winter
have a G35C with 18" no brembos
want to go down to 17" for winter (much cheaper and more availability than 18")
found some eagles that seem good, correct offset and width but they state a "BSM" of 5 1/2"????? what is BSM??

also what is the bolt circle diameter? 100mm, 110mm, 112mm, 41/4", 41/2"

when it is time to buy i am sure i will not be sold rims that do not fit, but for looking online i would like to know if what i am looking at will fit.

 

BSM is probably Back Space Measurement. You neet a bolt pattern on 5x114.3

 

Online places such as TireRack and DiscountTireDirect, if you enter the model car you have, will only show inventory that fits your car.

that would be 4 1/2" bolt dia which is very normal. most 5 bolts are 4.5 but i had a 90 cougar that was 4.25 and harder to find

 

been there, it shows what fits but not all of the specs so that i can compare elsewhere
