Big brake and spindle advice

[Northern Goat]

Not one to leave well enough alone I ahve decided to pitch the tiny 10.5" SSBC rotors I have on my 65 GTO and move up to larger brake kit.

I am thinking about installing a Baer Track kit. While I am at it, I think I will reitre my drop spindles and go with a B-Body spindles. I think I can acheive the 2" drop I currently have by cutting one coil of my springs.

Since I used this set up before I meet you guys and am not happy, I could use some advice.

Will this work?
Is there a more cost effective option?
Is there a relatively similar costing option that is better?
Any other pros or cons I have missed?

FYI: I am running 17X8 wheels with 4.5" of backspacing if this matters.
