Those Turner monoball bushings look delicious

They sure do! If I was going to track the car I’d seriously consider them.

I have the AKG 95A FCABs and I haven't noticed much harshness with them.

I thought these were the ones Justin had on his ZHP but maybe his were stiffer. I remember getting in his car, and it felt like a massage chair with all the vibrations. He would get to like 2800rpms and the car would shake violently until 2900-3000 rpms and it would return to normal. It was crazy.

LOL, I haven't had that happen.

Maybe it was the 75D's?

I'm not sure if they offered the 95A before.

Interesting... Thanks.

I wonder if there’s a chart somewhere which shows, in percentages, how much stiffer each durometer of poly is over OEM rubber.

Powerflex put some percentages on its site.

Bushings are produced in one of three durometers – Yellow (70A, approximately 25% stiffer than stock), Purple (80A, approximately 30% stiffer than stock), and Black (95A, approximately 80% stiffer than stock).

Sweet! Thanks.

I ordered the Turner 80A bushings. At a minimum they should provide some improvement over stock, but I want to start out on the softer side for now and see how the car feels.

I think you're talking about his poly engine mounts...
