One of the biggest pain points on my 1:18 scale Norev E28 M5 was its wheels. The side profile of the tires were way too tall, plus they decided to use some terrible wheels. I can't even figure out what Style number they are. Thankfully, I stumbled upon a set of Style 5 wheels off an Ottomobile E30 M3 on eBay. The seller lowered their price, then lowered it again, and then again, and then I finally pounced on them. They were pretty easy to swap onto the Norev model, just a matter of popping the old wheels off and gluing the new Otto's onto the fixed axles. I did have have to drill a new axel channel for the front wheels, however, to drop the car just enough to get the stance to my liking. What do you think, did I make a good decision?
Here are some shot of the car with the old wheels:
