As I’m getting my new euro downpipes in, which have little clearance within frame, I decided to replace my engine mounts that may or may not be original to see if that helps clearance.
The old ones were not split, but they sagged a tiny bit of upon inspection, especially on one side.
Here are my measurements (all include the giant spacer washer that goes on top, which is 2.4mm)
New mounts: 39.82mm
Right mount: 38.41-38.97mm
Left mount: 38.52-39.44mm
I also measured the height of engine from ground using the downpipes, and the engine height went up by 1.34mm.
Not a ton, but when there’s only 5mm clearance, 1.34mm is a lot, and I can see the difference.
