Stuntin' 101

anyway.. i have a 96 max lowered with h&r's and illumina's.
i currently have 235/45/17's now. i know, thats the ideal size. but im looking to get rid of my performace tires and switch to a grand touring. id like to, if i can , move up from a 45 series to a 50 to help smooth out the ride a bit more, and give a lil more protection against the potholes since id be going with a softer sidewall. i wouldnt imagine there would be any problems since i think its a stock 5th gen tire size, and i know alot of you guys run with those rims.

that being said, does anyone know for sure, if id have any cleareance or rubbing issues with the taller sidewall since the car is lowered, or if im in the clear. any issues with decreased braking power? id prefer to hear from someone thats running this rim/tire on a lowered set-up .. i know some of you guys are out there.. help me out here!! thanks in advance
