Wow awesome responses I really appreciate it guys! And as for bump steer thank for the tip definitely be using that during install. I'm going to use the specs I originally planned as a starting point in tweaking yo my preferences and to tune the car to my driving style. As for rsr in 235/40 r17 on stock ka, I may have over compensated, we'll see how it plays out for the next time I may run 215/40 or 225/45 if I can't break the tires loose on these!
