Can anyone tell me if 17inch alloys, rim width 7.5J, stud 114, offset 40, ET 45 will fit my car Mazda RX7 twin turbo 1993 model?

I have seen these wheels for sale, but not sure if they fit.

 

stock FD wheels are some of the lightest 16x8 you can find

i dont know why you'd want to downgrade by going to a 17x7.5, which is narrower and probably considerably heavier

anyway i think fd wheels are 16x8+50mm

17x7.5+40 will fit about the same.

-appearance wise (actually a little more 'sunk' - i.e. worse)
-inside it will have almost a full inch more clearance than stock wheels
-they will fit, barring any problems with the spoke design and brake clearance

 

Thanks for the advise, but i will only be using the car for road use & not racing.
