with stanza struts i just fit 15x6 +38 but they needed spacers

judging by spacers i have min on front would be 3mm

back i have 5mm but think i need more like 10mm

so with 6in width rim on front i would suggest +35 down to +25 on front, if the offset is higher you can use spacers to fit them

with 6.5in rim on rear i would suggest offset +26 down to +16 or even +10

back to the rims you propose..........

6in +20 on front would sit a fair way out from strut

6.5in +5 on rear would also sit a fair way out

should be ok with some vary minimal pumping of guards

my calculations are based on 195 tyres by the way, if you were running say 205 plus you would need the extra clearance for the tyre width... but your gonna have bigger problems again with getting them to fit inside the guards





hope all that can be understood

this helps....
