What Is The Lowest Offset?

[Canadian 32]

I am looking to replace the rims on my car anytime now. I am really looking into Weds sa-70's and 90's and I am wanting to go 8" front and 9" rear, either 17" or 18" ( i am not set on either). My fenders were already rolled when I bought the car, but it turns out with a baseball bat and no heater so the paint cracked and theres a bit of rust. I am thinking of getting a body shop to just cut the excess off, your thoughts on this? also thinking of flaring the fenders as well, what is the usual cost per fender for this?

so the available sizes/offsets are:

17×7.5J 43 5H-114.3

17×8.0J 32・42 5H-114.3 F

17×9.0J 10・20・35 5H-114.3 FR

18×8.0J 36・42 5H-114.3

18×9.0J 32 5H-114.3 R

20 5H-114.3 RR

18×10.0J 32 5H-114.3 R

any opinions would be awesome. thank you

on my 32 ive got on 18s, the fronts 8.5 offsets 21+ and rears 9.5 offsets 21+

the rears ive flared them 2-3mm out and the fronts im using 20mm fenders.

ive still a fair bit of space left on the rears but the fronts sit flush.

cars lowered by 330mm from the centre cap.

hope that gives u an idea.
