How much free-play should a B4 have?

[Hallsy]

I bought my B4 second hand, good condition, but has been used & raced so I looked at it as I would a 1:1 car.

There was significant play in the rear hub carriers (back & forth), and this was obvious that it was due to wear on the rear A-arm, so I shimmed this to take up the slack. Replaced shock bushes & lower eyelet/bushes, and all was good.

Front also had a fair amount of play, hub carrier back & forth, and also up/down. Some signs of minor wear on A-arm & hub carrier, but nothing major at all. Still, I shimmed these as well to take out the free play.

For a car that has adjustable camber, castor & toe, it would make sense to me for there to be as little free play as possible, otherwise any adjustments made would only be as so when the car was static!

Still, I realise that this is a plastic car, and so may have some free play as fresh from the box.

Could anyone who has had them from new comment? I took it out yesterday and imo, drives great, handling is predictable, tracks straight, etc - but then, I am a newb, and I wasn't racing!!

Any advice appreciated
