@fast... Not sure yet. Well... I like the red bmw roundels idea, and I have ordered the cupholders, of course... But will do a short track evening at brands hatch and decide whether to do anything more serious then. Brakes are a favourite upgrade of mine... I hate it if they go soft, so I'm a serial buyer of braided hoses, cooling ducts, slotted or drilled disks and even bigger kits sometimes. Suspension feels ok but I am intrigued by the z4 spring story, and suspect that I could do witha polybush or two and maybe a spring refresh at some stage. But this is definitely not a Trackday toy for me. It's a motorway mileage-eater with a spa day and a ring day envisaged for 2015 at most... But we will see how I get on at brands.
To all... Thank you for a really nice welcome. This is a great forum!
