Do y'all know if there's any way we'd be able to get the RS exhaust for our ST's? The thing sounds amazing, and it'd be cool on an ST, even if the intake sounds and all would be different. Thanks! Blake ..read more

Springs have been on for 3-4 years going to same shop for state inspection. Always had a small noise when turning the wheel all the way and shop passed it until this year. Said the springs were hitting the body. I took one side off and it is a slight rub there. I’ve tried different combinations now with the top seat of the spring and the mark on the hat and still slight rub. Cj pony parts video said all those need to line up with the struct mark as well. I’m at a lost at this point hoping... Eibach pro kit lowering springs hitting body ..read more

Hello beautiful people!! I've had my car for about a year. First week I got it I had a muffler shop get rid of my muffler and resonator. Many people tend to say they don't like that sound. Whatever the guys at my muffler shop did made it sound incredible. Very little drone. It was deep. Not raspy. And leveled off at high rpm. I got them to install my catless downpipe last week and boy did it make it sound like crap ??. It's raspy as all hell. I knew it was going to be louder. But man...

Two months ago I installed new (FCS rock auto) front strut assemblies and this week the left front started rattling again to what feels like a blown strut. I’ve down the push on the fender test and it does not seem to bounce. I also installed new endlinks. I’ll be reaching out to rock auto to try and get them to warranty it but has anyone ever had that happen to them? Disclosure. I live and work in NYC and drive to work everyday. Though I try to avoid potholes they seem to find me... new blown drivers front strut ..read more

New member (again), question before potential purchase.

Hey all, I'm back again. I originally deleted my account here after the dealership sold the original ST I was looking at. I had decided to just forego getting a ST, but then they ended up getting this black one, and I wanted a black one with low miles. It's a 2016 Focus ST (ST2) with approximately 36k miles. 2 previous owners and 0 accidents. My biggest issue, however, is upon scrolling through the Carfax, it appears the car has only had 1 documented oil change in all of its life. My fear...
