Hey guys, thanks for all the input!
I don't *think* I'll machine the chassis, I was thinking out loud more than anything...
The sheet of carbon is a good idea Terry, I could use the Tekin chassis as my template and bolt the T4 front end onto the carbon then goof with battery position from there. I'm starting to think that 3x3 is the way to go in order to keep weight on the rear.
I won't be able to drive it until March as there isn't an indoor track within a reasonable driving distance which is why I'm trying to get as *close* as possible before hand.
Keep the input coming!
