I'm at that stage in my build where I need to choose the rims and tyres and can't decide whether to go for 19" or 18" rims. I was originally going to buy a set of rims and tyres that were 19" for the convenience, but I've looked around and found some good deals on 18" rims. I know Andy Kirby used 19" and Tony Vortecks used 18" and both work fine. I think I'm correct in saying that smaller wheels give slightly better acceleration but a lower top speed which as I'm after acceleration is a small benefit? I'm slightly drawing towards 18" as they give more clearance up front and I've found some suitable ones for good prices, but any thoughts on either size?
