@BillNick Many thanks for the advice. I'd already ordered red stuff direct from EBC (arrived very quickly) and had a local garage fit them so all good. Decent saving over OEM. Not used the car really since and currently travelling so absolutely no idea if they are any good or not. Not worried as the consensus is that they are a good road pad.
In other news, just hit the 4yr mark, fresh service with Lexus and MOT. Now, tempted to look at lowering springs....if only to bring the front down a little as I think the back looks fine
