Hi, I just bought a 07 Mazda3 Sport GT 5-speed to replace my 03 Protege5.
On the test drive around town it was great but after I bought it I realized it didn't handle bumps well on the Highway. I did some research, found this forum and took the car to Jimmy at Street Performance. He recommended replacing all four shocks and the passenger side motor mount.
I was amazed at how fast and reasonably priced Jimmy's work is. The car now handles like a dream.
