I am still a few months away from running around with a pram, but I plan to fit some wheelie bars and some big as alloys. I was going to fit a blow off valve but I'm told babies come with them factory fitted ?? I'll probably go for some nice dangly things hanging over it as well... I will be running it on the natural juice to start with but I'm sure it will end up on the bottle!!! .But seriously I have started to build a new pedal car, it will run some kart alloys and slicks and I've machined up an alloy steering wheel. I am undecided about a body style but I am real partial on a mini AC Cobra......
