I noticed that my original bump stops were worn-out. The great thing about having a WRX is fun and practical use! I live in a rural area and am taking off our family‘s trash to the dump 2-3 times a week on my way to work.
These Perrin Performance bump stops are significantly larger and firmer! (See pics)
These likely can help if you notice trunk rattle over time, which I had. (My WRX is a 2019).
The OEM ones pulled right out with very little effort, highlighting their wear. BUY THESE, no tool necessary beyond a basic set of pliers to pull the old ones.
