I bought a standard ZX5 when I got back into racing a couple of years ago. I found big improvements by upgrading it to SP spec which used different wishbones, hubs and driveshafts. Over the winter I have built this car into a Rudebits DB4 (shortie) and at my first competitive meeting last weekend found that it was another big step forward. I would say the car is now somewhere between a ZX5 FS2 and a ZX6. The great thing about the lazer is it's ability to be upgraded if you haven't got £300-£400 to shell out in one go for a new car. Have a look in the kyosho section for more info
