Offset ranges
 

What is a good "rule-of-thumb" when trying to figure what the allowable change in offset is for Mercedes?

If the car runs a stock et37, can one go in or out off of centerline what amount?

i.e.- (W140) 8x16 et54, but you can use a et47.

Any help?

TIA

:D

Pat,
There isn't really a rule-of-thumb for this. Your best bet is go here:

Plug in your base specs and compare to the wheel you're looking at. You need to measure the clearance to the strut tube with the stock configuration to get an idea of how much clearance you have to work with. And remember, always test fit and verify clearance before driving! :)
