Can someone recommend any performance parts shops in Dusseldorf?

[Bubu]

My brother in-law is going for business for a few weeks to Dusseldorf, Germany. This is a good opportunity to get some parts for the Polo GTI.

I tried google but I cant find any tuning or spare parts shops in Dusseldorf. I speak no german so maybe my search terms in google are all wrong.

Anything may be of interest, engine mods, accessories, etc.

Can anyone help with links to websites?

if you cant find anything in dusseldorf, get any euro supplier to mail them to your brother's dusseldorf address, would be cheap or possibly no charge
