Thanks guys, I followed a lot of you for quite a while now and have been a big motivation to push the boundary, don't settle for the norm. I'm glad I was able to go a somewhat different route than most.
Little bit of an update:
I got in my 305 tires in last friday and got them mounted on my wheels. It's insane to see that even the 305's are stretched just a little bit. But they look f@#king tough as f@#k <3
So I took them back to my body shop guy on Wednesday so he can mount them to the car and see how the clearance is. I was already to hear bad news that they don't fit or we need to really trim the flares.... Nope, he told me I still had an extra 10mm to come out.... holy f@#k lol. So right now 18x13 with +20 offset is perfect for the flares. Now I wouldn't do crazy road racing but for just driving around and shows I think thats perfect. So now all that is left is to wait for the new rubber trim molding to come in and put everything back together.
Let me just say, 305's in the rear make the S look super f@#king aggressive <3 <3 <3
