Interesting stuff. If this is a stick car, those are the type of suspension upgrades necessary to reduce bouncing the tires like basketballs. Especially for a car making a lot of ponies. Nobody blindly makes 450+rwhp and doesn't touch the suspension!
Or do they?

Sure they do

Hey sweet! I ordered some from him. I went through my stash of spindles/hubs and turns out that from 6 all have spun the inner race at least one time and have very little press fit left. So I'd rather just use new ones for this project.
I looked at the picture again and zoomed in... it IS a groove between the compression ring grooves. What purpose does this serve?pressure balance groove

What are the pressure grooves or equalization channel on the 2nd ring land for?
The accumulation of gases that get by the top ring can unseat it. A pressure groove delays this action. This is why today's recommendation is to keep the 2nd ring end-gap as large as or larger than the top ring end-gap. It is a shaped channel that works by equalizing the pressure seen between the top and second ring with the pressure in the combustion chamber. This feature enhances ring seal, improving power, and engine life and fuel economy. The presence of this feature depends on your piston manufacturer as some have them, some don’t.
People who have 450+rwhp and stock suspension are leaving a lot on the table.
Is that correct? ($40 for a pair) Less than half the listed price?
People who have 450+rwhp and stock suspension are leaving a lot on the table. To some people that approach is unacceptable.QUOTE]
I leave mine stock so everyone else can keep up. Oh wait I don't make 450rwhp so guess I don't need it yet.
But really I do need to find out if the subframe I put in has the delrin or not.
