How is the clearance with the 245/40? Any issue with the top nut? Have you fitted the rears? I wouldn't have guessed the 40 ratio would fir but if so wow, there's more room then I thought
The clearance of the 245/40/17 is about 4mm between the tire and top nut. I'll check them during the first autocross and insert a 3-5mm spacer if needed. The rims are 35mm offset. In the rear, there's plenty of room for the 275/40/18. The rims are 32mm offset; so I used a 10mm spacer to bring them out to stock (22mm). Here are the pics.
