Back to the wheels. The 19" really suck on impact shock with stock RFT, you will feel & hear evey expansion joint road irregularity you come across. I got real good at spotting & avoiding pebbles down the road is daylight but it was much harder at night.
A switch @ about 4K miles to Conti DW 245X35X91 / 265X30X19 solve all the thump & crash issues from mile one. As for the open wheels & ugly calipers my solution (some love & some say RICE) was to cover them with metal covers. I have sprayed them heat resistant flat black with no silver trim. They just disappear into the background & IMHO are not at all offensive.
