no there not- there custom discs. there the same height and centre bore as the rover discs but the rover discs in question need to have the bolt pattern changed as they are 4x114 and not 4x100. so TSR must buy them in bulk with the specification changed to include the pcd change.
ive got this setup myself on my shelves and it took bloodynages to find it all out.
im using 280mm honda legend discs (same as rover) with slotted holes to make them 4x100. the main advantage of them is the disc height as it means i could get my 4pot willwoods on without wheel spacers and the brakes fitted loads better.
