who makes best coil over front suspension

Neat car Mr. Ehrenberg built.

In reading about it elsewhere I saw where he made some significant brake
upgrades as well.

So what was the total cost of his front end modifications?

I talked to him on the phone and built a copy of the brick in my '72. I spent ~$2000 from top to bottom. FF did my K-frame, I used poly bushings all 'round. MP T-bars and springs, and I did shocks and stuff like reinforced LCA's. This included updating to '74 K-frame and and big-car brakes and rotors.

What I didn't do, yet:
torque boxes and frame connectors,
Diet
Battery relocation

The car is on rails. The roads where I love aren't twisty enough to push it. I need to take it to Arkansas.
