Bouncy car

I wonder if the suspension is bottoming out on the bump stops or the struts. How much did you lower it? You may have to take it to an alignment / suspension shop and have them look over the install. When I lowered my 2008 Bullitt Mustang an inch I had no issues after having the front end aligned.

I lowored 1.5 I still need the alignment but first I'll be switching the outer tie rods.

What tire size do you have on the Mustang?

All four are 18

What tire size?

235/50ZR18 101Y

Tire size appears not to be the problem. I wonder if a rubber bump stops are bottoming out causing the strut not to travel to its full movement. When I lowered my Mustang just an inch it did ride a little harsher, but it was not very noticeable and it did not feel bouncy at all. Look at the link for what the bumps stops look like.....http://www.americanmuscle.com/frpp-jounce-stops- 0513.html

I'll have to change the rubber bumps

I hope that fixes it for you. Best of luck with it.

Thank you so much. Every time I drive it seems like if on a jdm haha
