rough ride
 

so hears the deal. ive had my mustang for about half a year. and the stock ride quality was not bad at all. then i hit a big piece of truck part on the turn pike and fed up my weels. then i got black fr500's and new tires. and now my ride is a little rough. so idk if the tires just need to be worn in a bit or is there another peice of suspension that i should replace. to the best of my knolage its all 10 year old stock parts. so idk what to do.

It's normal to have a rougher ride when you upgrade to bigger rims and tires with a shorter sidewall. If you push down on your car and it kinda bounces, when you let go of it, your struts or shocks might need to be replaced.

What size FR500s did you get? If you went bigger and wider then your ride WILL get rougher. On a taller rim you have to run a shorter tire wich means there is LESS side wall there to help cushion bumps.

ok that is prob what it is. cause i trust my shop guy. and he checked every thing out. i was just checking. i got 17x9s all around. yeah i know a little conservitive but i need to be able to rotate them. ill have to get rid of the change in my change slots cause now they rattle wile i drive.
