Should be ok the callipers on the front are thicker , they probably had to be spaced to stop them hitting The calliper.
Well I put 5mm spacers on the front of my old 5 to clear caliper with some Rota Gtrs that came of an altezza
I found it never handled great after I always found it pulling to the left and once in the wet I dropped the boot and the arse of the car stepped out nearly lost it .
I put my wrc tarmacs back on and it felt much better
But this probably depends on the type of wheel
