The front suspension has made it into production in the form of the LAW35 upgrade pack and the 077b ZX5-SP kit.
Luckly for all of use the car uses the standard chassis not a BJ4WE-U-Like .... thankfully.
The ZX5-SP is a fantastic car, I'm loving mine. I am fast coming to a set-up that seems to work everywhere although I am still changing the car every run to get used to the magnitude of each individual change. In the end though I keep arriving back at the same combination which runs sweet .... almost there
