What is the Guldstrand mod?

[HWYSTR]

Not sure if the brakes are the same on the LS1 T/A as the C5/6 (for the ATS spindles), but shouldn't be hard to figure out. My guess is no though. On the B-body tall spindle, look at Kore3 stuff...

Springs & shocks, my personal preference is the Global West stuff, it's engineered to work as a package, all the stuff works great together, and there's no room for mistakes really. Support I've found is great, icing on the cake. Shocks, QA-1s are the way to go, but you can use Bilstiens or Konis with great results too.
