hi, what is the offset on a 4x4 saph? and will a 17'' grp a wheel fit et15, and if theyll fit will they need spaceing?

 

would be very suprised if these will fit without scrubbing,first you would need longer wheel studs or group a conversion nuts but et 15 wheels will stick out alot more especially at the front!

seen 7.5x17 et 18 with 205 40 17 tyres on my 2wd saff and also
8x17 et 25 with 205 40 17 but was also running coil overs!
