The correct 15" alloy offsets

[ventura]

What is the best offset for a 15" alloy so that it fills the arches without the need for spacers. I had 18" speed lines on my 197 that were perfect and didn't need spacers.

Looking at getting some new wheels for my 172 cup either 2118s or pro races and wanted to know the best and correct offset etc?

Standard offset on a 172 Cup is ET38.5, so something within a few mm of that will be more than satisfactory.

I don't think 2118s come in many offfset variants, but the TDs have more choice.

Buy the wheels you want, then you can add spacers afterwards if you want.

Williams wheels sit really nicely without spacers imo. Can't remember the offset off the top of my head but think it's 35.

35

36 for Williams
Still require spacers imo to fit truly well
