Elise S1

Timken JRM3938A.

Elise S2 Non ABS

The Rover S2 uses 3 identical bearing packs without built-in sensor and 1 pack with a sensor for the ECU (which then relays it to the speedo) on one of the rear wheels.

These bearing packs originate from the Opel/Vauxhall Astra G front axle. You can use cheep Vauxhall Astra Mk.4 bearings from ebay on the front but not the rear as the dirveshaft splines are different bentween GM and Rover.
