Looks like you've got your work cut out

but good base cars and like Henk said I'm also loving the trans cover very cool.
The rear shock mount you have is off an XLS and the one you have on your carbon chassid car looks like a bosscat one. I have an Atomic Carbon bosscat one on my Procat for more adjustability over the standed one and it's 3mm thick.
And I also like you cougar steering setup was that out of choice to centralise the weight or out of necessity? I run my own modified SX3 setup
