Thanks for your comprehensive reply. Currently running standard MB Avantgarde 16" rims with Continental 215-55 tyres. Like the look of the AMG 17" and 18" monoblocks. Can they be sourced outside MB? Don't think ebay would work for me in Ireland. Looked at a brake upgrade kit at www.brembo.com but at $3300 it's too much. Think I'll go for OE Brembo discs and ATE pads. I reckon I've got the same performance now as the 320CDI (drove one a few weeks ago-wicked). Do you know the standard wheel/tyre/brake setup on that? Also running Castrol Magnatec oil which I'm convinced made a difference to throttle and turbo response.Also using K&N air filter. Going to fit K&N oil filter. Anything else I should be thinking about??
