So this is a TEST FIT for now.. I need to run a different tire up front to help clear the fenders.
I didnt have any issues with my W210 AMG Monoblocks, but that wheel was a 18x8 ET 31 up front and a 18x9 ET35 for the rear with 245/40/18 and 285/35/18 tires.

But with the SL55 wheels.. they are 18x8.5 ET30 and 18x9.5 ET33. so I need to change the front tire to a 225/40/18 for fitment and I should be able to turn my steering wheel full lock without rubbing too much!!
with the 245 tire set up I cant even turn my steering wheel half way before it touches the fender (as you can see in the pic!!) still keeping the 285/35 rear tire.
so as soon as I get tires I will put them on and take new pics.
