Aim for 8j front , 9j rears & et numbers around 40
8.5j fronts , 9.5j rears will be more common & will work but definitely don't go under et40 for the fronts , rears will be fine down to low 30s
Once wheel sizes are known choose the tyre sizes to suit & don't just go off whoever is supplying the wheels

probably, keep in mind that I'm stock sport suspension.
I have a feeling that on eibachs it'll rub a little and I might have to go for 215's up front. We'll see next year

I fitted the 313s on mine with coilovers on a 225/35/19 which are the same specs as your style 225M wheels with no issues even at my height.

OP has asked about 19s not 18s , does make a difference depending on tyres , springs , roadster , coupe etc , so many factors as discussed many times . there is no one size fits all Zs magic formula

over-all the size is pretty much the same ? you go up in size and go down in sidewall?mr wilks wrote: ↑Fri Aug 11, 2017 12:50 pmBuckz wrote: ↑Fri Aug 11, 2017 11:33 amI've got 18'smr wilks wrote: ↑Fri Aug 11, 2017 11:22 am Aim for 8j front , 9j rears & et numbers around 40

Supposedly yeah , which is why i said once the wheel size & offset is known then you can decide the tyre size which is as important as the previous 2 sizes .Buckz wrote: ↑Fri Aug 11, 2017 1:47 pmyou go up in size and go down in sidewall?mr wilks wrote: ↑Fri Aug 11, 2017 12:50 pmBuckz wrote: ↑Fri Aug 11, 2017 11:33 am

I said not to go under et 40 as the op specifically mentioned he didn't want rubbing which i interpreted as he'd rather not play the game of chance & end with the usual " it just rubs a very little when full lock or when i go over a certain hump in road " nothing worse imo
