Hey guys I just bought some used sf challenges today and I was wondering how I could find the offsets of the rims? It does not have the stickers that go inside the rims and I'm pretty sure they are 8.5 front and 9.5 rear...any ideas?

 

Measure the lip from the center of the hub in millimeters and then cross reference the volk site that has the offset charts for each wheel.....

 

Or you can look inside the barrel. It should have the P.C.D, size, and offset.

 

You bought them without knowing the offsets?

I hope they were a decent offset.

Let's play "guess the offset"

I'll guess they are +21 F and +23 R

 

haha yeah the guy who owned the rims bought the car with the rims and changed it out for some 20" chromies...here are some pics how the wheels line up with the fender...there is a 2.5 in lip on the rear and about 1.75 up front...here are some pics...any ideas on what the offset might be?

 

That's a great idea for a seperate thread here on my350.
