[s-cars] Is 225 too wide?

[Sam Clarkson]

I'm running standard height springs, however being an aging avant,  
the rear is down a bit which will be remedied with the addition of  
the Bilsteins which I'm having extra  snap ring grooves milled into  
as we speak (er um type). Up at the rear will increase the front  
caster and might be the whole problem sloved, yes?
