I jus had a quick question...

okay, say u bought wheels off ebay or you bought em off someone, Its jus the rims, no rubber yet. You found out that is 4x100(which fits our cars). How could I prove its the right offset and that this person isnt ****in around w/ you.

Obiviously you could put em on your car, but there is no rubber yet, so it wouldnt really help.

Thanks in advance!!

the OZ/LS has a bolt pattern of 4x114.3.
the ES has a bolt pattern of 4x100

the right offset is +42.

Actually, the right offset depends on the width of the rim. Since offset is measured from the middle of the rim, the wider you get the more offset you need to keep the wheel inside the wheel well. The stock OZ rims are 6" wide and have 38mm offset I believe. If you get a 7" wide rim, you want 40-42mm offset, and if you get a 7.5" wide rim, you want 42mm-46mm offset.

And like Bobaab said, the OZ uses a 4x114.3 bolt pattern. Only the ES uses 4x100.

Ok, here's a quick tutorial. Not all wheels mount to the car right in the center of the rim. Offset is a measurement of how far off from the center the rims mount. So, if the rim mounts in the very center (most RWD cars use this) it is a 0 offset. In order to reduce torque steer on FWD cars, they have a positive offset, which means the mounting location is towards the outside of the rim. Deep dish rims usually have a negative offset (mounts towards the inside) to allow for the extra lip on the outside, which is why you don't see many deep dish rims on FWD cars. Now, offset is measured in a simple unit... milimeters. So, that's how many mm away from the center of the rim the mounting location is. Make sense? Or did I confuse you more?

nope, 4x100 is only for the ES. The OZ and LS have 4x114.3. 4x100 is completely (well not completely) but different ENOUGH from 4x114.3 that it will not fit.

by center, u mean the center compare to the width of the rim, correct?

Bobaab, yes center referring to the width.

ok wow that makes a lot more sense now..i think i got the center confused. instead of the center compared to the width, i thought it was the center as in the center of the diameter..but i knew that was wrong. lol

i never knew the 0 offset was at the center, this cleared it up the most! thx man! off to give advice to people

So if i took these rims and did this measurement thing, could i determine what the offset of these rims are??

I suppose there's a way to measure offset, but I'm not sure if it's measured from the inside of the rim lip or the outside. But my best guess is you'd want to measure the width of the rim, then use two straight edges and a measuring tape to find the middle on the inside of the rim and count how far off the inside mounting surface is. I wouldn't expect any accurate measurements from that, but you'd get a good idea from it.

8.5 is way too wide for a Lancer. You need at least 235 width tires on that rim, which will rub. That and that offset would put the tires about an inch outside of the fender. 7.5 is the widest I would recommend for the Lancer (7 is the widest you need to go, 7.5 wil work ok, and 8 and wider will be wider than the tire itself!)
