Nice!
I'm just finishing up my JRX Pro I've converted back to a JRX2 with the link rear suspension I still had from when I raced it first time round
As the others have mentioned there was no bumper on the original car. My Pro came with an RPM wide (ish) bumper and it just looks ugly. I do still have a small Losi bumper but it actually fits by raising the front bulkhead. Spacers come in the packet to so this and also to raise the steering bellcranks so everything stays level.
I think it looks right without the bumper myself.
