Offset Help Hey gang - I’ve read up a ton on this here and elsewhere and am still confused, so looking for your guidance.
In the process of lowering my 98 Formula w/ BMR springs and Koni Str.t shocks and found a weird discrepancy. Front drivers wheel (TSW Kyalami, owner before me put those on) has a different offset from the passenger side. Both are 18x9, but driver side is 35 offset and the passenger is 20. I’m past figuring out how that happened (maybe installer mounted wrong)… but now I’m wondering which belongs where.
I like the wheels and what to keep them, but should the 35s go in the front and 20s in the rear or vice versa?

Thanks guys.
Yeah it looks like whoever mounted them put the 20s on the passenger side and the 35s on the driver side (front and back). The btch of it is that the fronts both are 265s and the rears are 275s… so I can’t just rotate them without changing the tires out as well. Fail.
All are 18x9. The offset numbers respectively are indicated inside the rim as “35” and “20”… doesn’t indicate positive or negative so I assume it’s positive.

Yeah, just pay to have the tires switched and put the 20s on the rear. Luckily you have a Pontiac and they accept that offset better than a Chevy will for some reason. I have both and +36 ZR1 wheels stick out more on my Camaro than they do my Bird.
