Alright so l put 17 is on my civic and now when l hit a bump or have a full car the tires scrape against the wheel wells and when l turn the front tires dig into the side of the wheel well. l think its because my shocks or something in stock suspension is soft/weak. So l bought some adjustable shocks should this help? and could this be because l put a rear sway bar on?

if u r hitting with stock springs, ur tires r too large, or u r hitting bumps too hard.

if u r hitting with lowered springs, u r too low, ur tires r too large, or u r hitting bumps too hard.

adjustable shocks might help by keeping the suspension from travelling too far, but that is a band-aid for the problem, it is not a fix.

putting on a rear sway bar likely did not cause the problem, depending on how big it is & how u drive, it might actually be helping a bit.
