I was just wondering if anyone might have an idea i dont really. Im looking at these 14" wheels for my 120Y but the offset is wrong does anyone know what mm would be the best wheel spacer to buy? it touches the strut and this bloke i know said 10mm would that be enough and how much are they from like an auto shop or whatever cheers.

Of course, you could always pass on these unsuitable rims, then keep ypur eyes open for the right ones, & get it right first time. They are out there, & they don't cost the earth, but sometimes it requires a little patience to find them.
What size do you have in mind?

I was thinking 14" how big can you go before #### has to be made custom like maybe 15 or something?

for 14" or bigger wheels you need diffrent struts to get the clearance on the spring seat, stanza struts are the typical upgrade and do a lot for your handeling and stopping also

for 14" rims you need to use 60 profile or lower tyres aswell, typicaly 195/60/14s are used
