STi 2014 on engine pitch mount bracket failure
 

Hi all,

So I've bought a new shape STI to replace my 08 hatch. Hatch has 122 k on the clock and going great. Picked up the 2014 with a partially stripped engine due to engine failure.

I have had the engine replaced but have noticed that the pitch mount bracket on the bulkhead is torn and split.

I did some research and found this is a common issue and that mid 2016 the part was upgraded on the production line. Also Subaru America issued a recall and a warranty extension.

I've spoke to Subaru UK who say there isn't a problem.

Anyone had a similar issue on their 2014 on STI or WRX? Just trying to get a handle on the issue and more data to speak to Subaru UK

If this has been covered before please let me know and I'll delete the thread. I did search but didn't come up with anything. If you have a link to the thread it would be appreciated.

Thanks

Pic would be nice for reference purposes so that anyone buying should know where/what to look for in case they land upon this page from a search

This popped up when I was researching buying mine.
I have only seen bracket failures in the US for some reason, maybe because the are way ahead of us with tuning on the latest model.

Perrin do a strengthening bracket, looks a ball ache to fit though.

Designed for LHD and bolts to where the LHD clutch master cylinder is located so would probably need some modification for RHD use.

Upgrading to a hard race pitch mount obviously increases the risk of failure.

Would a more substantial weld around the bracket - bulkhead before it fails be a permanent fix or does the oe bracket need beefing up?

Siv

I wouldn't want to weld that back on. There is a high risk of fire inside the car up behind the dashboard where it's difficult to put out.

The Subaru warranty solution is to weld a stronger bracket on.

I may be wrong but that’s what I’ve seen on the US forums.

I wonder if a Perrin bracket is planned for rhd?

The gif file above shows factured spot welds and a tear through the lower section
Picture below shows tearing of the backet on the other side and possible lower spot weld failure.

Looks as if there are at least two potential crack propogation sites so no beefing up of the bulkhead welds would have prevented the failures - probably would have speeded things up.

I've obtained a replacement bracket and there are 11 spot welds. However when I looked at the Subaru America bulletin this part has been superseded. The new mount is 2mm thick instead of 1mm. Local dealer said there is no superseded part. So I supplied the part number and one is coming from Sweden apparently it's for the levorg STI. We will see. Still think Subaru UK are trying to duck this in a not sold many, head in the sand kind of way. Please check yours.

Interesting.

Definitely a market for a RHD support bracket then.

Maybe we should contact Perrin and see if they can produce a kit?

Part number for "BRACKET COMPLETE-PITCHING STOPPER" changed in May 2016 (mid way through MY16 European and ROW production) FROM 51234YC000P TO 51234VA0809P and is used on both saloon and wagon (Levorg)
