I'd go with the 4 inch.

Not sure where you can get it in Poland but I got my mods from this site, great customer service, fast delivery, all good. They do international shipping too i think. You can give it a look www.mlperformance.co.uk They're on Black Friday Sale so I'm looking to get more mods myself.
