Ricky the DJ Pro Module rear suspension kit was developed for rubber tyre racing, it allows you to run a very soft setup at the rear and that's no good when you run foam. 1 or 2 guys that run Tamiya Cup changed over to this setup but they never quite got the hang of it, they have changed back to the regular style rear suspension. The other thing you need to be aware of is that the arms are made of aluminium and may bend in a hard impact.
Just my point of view but I think you could spend your money more wisely on other areas of the car.
