Fellas.? I've done months of research on this exact topic.? Allow me to share my findings.? My car has the sport package and I wanted to upgrade to 20's.? I chose to go with BMW Radial Style 32's but I'm powdercoating them black.? The wheels are 20x9 in the fronts and 20x10's in the rear.? Now, in order for you to avoid any rubbing issues or any speedo issues, you must keep the overall diameter the same or as close to stock as you can get.? That being said, this is where my research began.? The proper size tires to use that conform the best to the OEM diameter are 255/30 in the front and 295/25 in the rear.? Those sizes give you the closest match.? OEM is 25.6" and these 295/25 rears give you a 25.8" overall diameter.? A 285/30 is 26.9".? That's when you'll first have to start rolling your fenders.? Hope this helps.

i have 255/35/20 and 285/30/20 and I don't rub with 5 people in my car, and I went over a railroad crossing at around 45 with all 5 in the car (not light people). could be the perfect offset of my wheels? dunno. see below...

Hey lip, your car looks so sweet man. All you need to do is debadge that baby and put a black grill on the car and you'll really set it off. Quick question for you, do you know the offsets you are running? Thanks.

I am running a 20" by 8.5" with 245/35/20 all around... I wish I could have gone with a bigger width but money was an issue... but now I have lowered my car and if I were to have had a bigger width I really don;t think it would have worked out... Right now my strut plate and basically 1cm away from my tire... at first it did rub but we put in the strut to much and then that fixed the problem... but the only thing I have a problem with is when I exceed 40mph (sometimes not all the time) I get vibration comming from the car... now from what I heard some vibration is somwhat of a norm... but when I am on the highway going about 60+ I get an increase in vibration... but still its not constant... it only happens when it wants to... I dunno what could be the problem

Check that, I see the size in your post but what about your offset?

soc_fans... i must say i really really like those wheels... i almost like them as much as mine, and since I feel I must put a DISCLAIMER on the bottom of every post due to recent hating attempts, im not saying this in any way knock your wheels. im simply saying out of all wheels i've seen on this board, those rock bra.... and since everyone has their own taste i simply chose what I chose for my needs and you did as well... and a good choice. like i said.. BIG LIP IS A MUST, if not just go buy some axis wheels or w/e. again, nice ride
