thanks for feedback all.
the tyres are michelin ps3, 225/40 and 255/35. wheels specs are 18x8 + 40 and 18x9 + 45.
ill just start by saying that i do think the rear wheels and the poke looks amazing. but overall its too hectic for me, and i dont like how it the scrubbing impedes how i drive.
i wasnt actually aiming for the rears to sit like that (i wanted it to sit more like my fronts), and had intended to go with 245 to help with my clearance. unfortunately i couldnt source a matching set on the day that i needed so i just went with 255 and thought it would work haha. so it looks like ill just start with a guard roll, and then some camber if its required.
