Focus ST/RS Transmission Disassembly | Speed Perf6rmanc3 Brass Synchro Upgrade

If you own a Focus ST then you might be aware about the ongoing transmission issues that commonly occur with gear engagement and synchronizer failure. Many Focus ST/RS owners have even had synchro failures on stock vehicles. This becomes a nuisance if you have a high powered Focus ST since you'll only break it that much easier...
Speed Perf6rmanc3 sells a brass upgrade that has been proven to hold together even at 700 WHP and in this video I film Pablo from Speed Perf6rmanc3 tearing down a Focus ST transmission at their shop and show you the actual part that fails in these transmissions.
When the tab on the synchronizer ring breaks, the synchronizer no longer stays in alignment when the clutch hub moves to engage the selected gear.
These brass synchro rings shown in the video can also be used on the Focus RS transmission:
