Hi All.


I have A classic with ABW flared arches.


I have 18" Rota's at the moment, which I am not keen on.


I will be looking at changing them for some 17"s, but I'm unsure of what ET to get?


The Rota's are 9.5 and an ET of 35, but they don't really fill the arches (there is a picture in my other thread titled out with the old mirrors).


I am looking at 9.75 (only because I can't find 9.5 in the style I want).


But I'm unsure of what ET to go for, I have seen a picture which are "supposed" to be 9.75 and an ET of 20, but they really fill the arches out and look like they may rub.


Any comments, answers or pictures would be much appreciated.


Many thanks in advance.

This site is handy for calculating offset.
If you measure the clearance you have between your current wheel & arches you can adjust the ET numbers until your happy.

Example:
Current wheels = 9.5 x ET35 & there's a 20mm* gap between arch and wheel.

New wheels = 9.75 x ET25 = outside position is 20mm further out. Inside position is the same.
*20mm just an example. Measure your actual clearance.

 

Hi Jonny cut corners,


That's brilliant, many thanks mate for your help.
