I like Dragula’s way of thinking.... I like “easy”, and to increase “easy”, tube K/rack steering/coil over shocks sure frees up a ton of space for go fast parts!

Starting a racecar from scratch I’d go 9” derivative or S60..... this is coming from a guy that had 8.75 rears in 2 cars that Ended up with Danas.

Fiberglass doors and fenders...... way too much BS for what your trying to do imho.
