That's what I'm thinking! They will make them (almost) any offset I want and I need to know what others have tried. I'm thinking 18x8.5 et 30 with 245/35/18 on the front and 18x10 with 275/35/18 et 25 on the rear. I'll be using my "extra" spacers with my stock wheels as an experiment to identify the offset to get a 245 on the front. In the past I've used 235's on the front with no spacers, 235's with 10 mm spacers so I have a good idea just how much space I have with my lowered car. With stock rims and tires (lowered) 5 mm on the inside and 15 mm on the outside. On the rear???? I ran a 265/35/19 with minor rubbing on the inside of the wheel well from the extra height. I tried a 5mm spacer with the 265's and it rubbed on the big potholes. So I'm thinking I have 8 mm on the outside. On the inside I don't know for sure. Experiences, observations, opinions are welcome.
