New member looking for 65 Chevelle suspension advice

[TOPGUN86]

Hi all!
I’ve owned my 65 for over 20 years. It has gone thru many incarnations. Started with a stock 327/powerglide. Stock suspension.
In the early 2000’s I upgraded the suspension and brakes to std GM 11” discs front and rear, lowered spindles. Ran that configuration for a few yrs. next was a transmission upgrade to a 700R4. Around 2010 I put in a LS3 with a T56, ac, new interior. Been running this way since. Done many power tour trips, it’s a fun car, but now it’s time to get on the newer suspension \brake bandwagon. I’m in possession of complete C6 brakes and am thinking of installing these. Looking for suspension advice. Been leaning toward ABC or Speedtech with the AFX spindles.
Thanks!
Chris
