15" Wheels without modding?

[Opelfreak]

Can I fit 15" rims without rubbing or having to mod something? If so, what ET do they have to have?
Nova is lowered 4cm and like to fit 195/45 R15 tyres.

Should be ok as long as you stick around et45-49 and so long as the dampers and springs aren't too soft

Thx. Think I'm gonna look for some original Vauxhall rims in 15", maybe Astra GSI's or some sort.
