I have the same tires as you and am keeping my stock wheels as well. I am about to order the BORA 1.5 inch spacers but wanted to see if you have leveled the front and replaced the UCAs. If so what level and brand did you go with for the LEvel and UCA. I currently purchased the RC 1.5 and UCA recommended on their site and these forums
To recap:
Do you have a level on the front, what brand, size?
Did you replace UCA, what brand and type?
Is the mud flap and bracket mod difficult?
