I have an offset question for my EVO 8. I have done a search and can't fined anything. So hopefully someone can shine some light on the subject for me.
OK...I am wondering if 17x8 +40 offset will fit on my EVO 8? Will i have to do anything to make them fit? I am clueless on offsets for my car. Any help would be great. I see you guys running a smaller offset but you have to put spacers on them or roll the fender. Kind of want to stay away from having to do any mods to my car just to get rims to fit on my car. I want to stay away from the roller skate look..lol. O h yeah the rim is a nippon F-2. well thank you all for reading my post and i hope someone can help me with this before i buy these. One more thing is someone can put up a guide line on how offset works and what to look for would be great to do for noobs like me and anyone eles.

 

come on people. 20 people have looked at this and still no help.

 

very likely that they wont clear ur Brembos. ur stock wheels r 17x8 +38, why would u want to run wheels that has a narrower track than ur stock wheels?

 

17x8/9 or 18x8/9

with a 29-35 offset would work nicely

+38 is stock...subies run in the 40's

 

-2mm, on each side, is not that huge of a difference. Remember 22mm=~1 inch

My general rule of thumb when picking rims, is to keep the center of the rim in the same spot as the OEM rim.
So if the OEM rim is 17/8 with a +40mm offset, and you want to go to a 17x9 rim. You should decreas the offset by ~10mm. So a good set of rims in 17x9 would be a +30mm offset. NOW, the only problem you may run into is rubbing on the inside fender, as the new rim will stick further in towards the fender by about .5 inches.

If you get rims that are too wide (i.e. 10" wide) you will have to push the offset to around +20mm, and may have to roll your fenders.

In general, for every inch wider rim you choose, decrease the OEM offset by about 10mm.

Offset is how far the hub mounting point on the rim is from the center of the rim. So a +40mm (or +38mm) offset is 40mm away from the center of the rim towards the outside of the rim.

Deep dish rims would generally be a 0mm to negative offset, as the hub mounting point is further towards the inside of the rim.

 

P.S. you can also change your offset by using spacers.

If you use a 5mm spacer, you effectively decrease the rim offset by 5mm.

so, a +40mm offset rim with a +5mm spacer makes the rim act like a +35mm offset rim.

Generally, you only want to use spacers as a last resort to avoid rubbing, as they tend to put a bit of stress on the lug bolts and hub assembly.

 

thank you for the help people. the info you all have givin me has really helped me out a lot. i didn't know my stock off set was +38. i thought it was +36 or something like that. now i know and knowing is half the battle. G.I. Joe!!!!!....lol.
