E36 parts and tools in london

[madnod]

Hi,

i'll be visiting the UK in the next couple of days for 4 days where i'll be staying in london for an event.

i have a euro 95 E36 328i, i am looking forward to use this opportunity to buy S52 cams for my car, also i am looking to buy the cams timing tool.

anyone can advise please where i should look in order to find the tools and the cams? i'll be around Westminster area.

thanks in advance.
