The link below will show my Delta XP4.
For those of you who don't know, the Delta XP4 is basicly an improved Evolva. The XP4 Has many improvements over the Evolva. The modded chassis is finished nicely made with T6 Aluminum.
The radio tray is modded as well and has a provision for a personnal transponder mount.
The dog bones are made here in the USA.
If your looking for more out of your Evolva, you may contact me @ the link below for chassis and radio tray plates.
Your setups will change if you go with the chassis. It is stiffer and lighter and will improve your lap times with a slighty different setup!
