Thanks for the insights guys.

Very true they are lighter which is a nice perk for sure. I started out with a Honda fit that lost 0.1s in a 2nd gear pull for every 15lbs of dead weight you added and the AC was good for 0.9s lol. So potentially saving 16lbs of rotating mass is stuff of wet dreams haha. Saving 8lbs of rotating mass on the front end ain't bad at all.

Definitely don't expect more life out of the rotors.

I may still put Paragon Rotors on for the fun of it, but we'll see how I feel on Black Friday.

Perhaps a little better thermal separation from the hub and a marginal heat dissipation improvement from directional fin optimization is all you get. Can't hurt I guess. Albeit I don't see much reported with track use causing wheel bearing issues on our cars.

I'll also do titanium shims too regardless to help keep heat out of the calipers.

So I'll be doing at least the brake deflectors and titanium shims even if I stick with OE semi-floating rotors

If anyone else has thoughts feel free to add more the merrier!
