Well if you've got to this post and everything appears clear as mud, hopefully this will help.
Today I went to GSF to purchase two rear wheel bearing kits (I get a small discount)
The two kits I was going to purchase were Pt No QWB201 (various VW's, Audi's etc) The price for each kit was £8.
Whilst at the GSF service counter I was offered an alternate more expensive kit (OEM for the various VW's, Audi's etc), but still the same spec as the QWB201.
The kit I was offered was GSF Pt No 413VG0150
OEM Pt No 41311J
I took them up on this offer... I purchased two kits for £32.32
As noted by others, the seals dimensions are as the Lotus OEM with one exception, the lip is about 1mm smaller.
Please see the following photographs of me fitting the bearings to a Brand new Lotus brake hub.
The second to last photograph show the bearings and seal fitted to the brake hub
The last photograph is just to show what the seal would look like when the brake hub is slid over the axle...a perfect fit.. having the lip 1mm smaller seems to make very little difference
