Hi,

Im new to the forums, i just recently purchased a 2017 ford focus st and after driving it very carefully for the first 1000 miles i finally got on it in first gear and after hard shifting into 2nd, i noticed as i released the clutch, there was a jolt and it sounded really bad, almost felt like i went over a speedbump or a bump in the road even though there was no bump. Just curious if anyone else is having this problem or if anyone has input please let me know!

Thanks!

Motor mount
The motor is rolling and hitting the firewall on hard shifts. This was common on the 13 and 14s. Not sure if they went to a softer setup on the 17s.

so a rear motor mount should fix the problem?

RMM will help. Mountune seems like a great option. Plenty of threads on the subject...
Switching into 'Sport Mode' is also helpful if you are an aggressive driver.
Normal mode has too many electronic-nannies, that hinder sporty driving.
Good Luck.

Happened all the time in my 2016 and was a huge pain any time I tried to quickly merge anywhere. Put on the Cobb RMM and it is so much better!

Nothing hits the firewall; CPe did a video years ago showing what is actually going on. The factory mount, even the updated eFocus mount, have bushings that are so flexible that the mount housing itself hits the chassis where it is mounted.

I've never seen that. Good to know. When we first got our cars everyone was saying firewall. I put the E-Focus mount on after 2 weeks and never had the issue again even with the EFR upgrade.

2015 with the stock mount (Efocus I believe?) and it's never been a problem for me. Not saying I couldn't feel the difference if I upgraded but its never been an issue in my car.

I was still able to get it to bang pretty good after installing the eFocus mount so I switched to the adjustable CFM mount.

I have a 13 and had the TSB done. This included all three engine mounts and clutch line (added a restricter). This kinda helped but did not eliminate it. You need a stiffer mount. I went to the Boomba and later switched to the cp-e stage 2. Now I have all three cp-e mounts and JPC clutch line and love it.

I haven't had this issue on my 16. Try with sport mode on and don't dump the clutch.

From a description sounds more like a wheel hop.

^^^^^^:whs:^^^^^^

Sounds like a combination of both wheel hop and the mount bang. Mind did the same thing until I switched out the RMM for the COBB, no more problem and it gets out of the hole much better.

I installed a mountune RMM + traction bar and there is no wheel hop nor banging at all. Highly recommended set up.

Wheel hop and motor mount noise. I get it when wet out and the tires spin.
