Well I fitted my shocks, the driver side one is a real pain due to access, but extracting the old shocks from the suspension arms and getting the new ones back in is also a pain. However, all done and top mounts and drop links also replaced - no more clunks.
The grating noise on corners turned out to be a stone caught in the brake caliper mount. And as for the shocks, well I ordered Boge but GSF delivered Billsteins, I assume they are the same? The ride is fine, so no complaints there, the old ones had done just short of 150,000 and were weeping oil slightly, but to be honest I think the difference is minimal..
