What's the major difference in between the Poly links and the spherical bearing links wheel hop wise?
I understand for pure performance applications, your going to give up NHV and comfort for the sake of performance, so the delrin links would be the way to go, but how much am I giving up over the delrin if I went Poly? Race cars are meant to do one thing, go as fast as possible around the track or down the strip. NHV is a non-concern. But my GT PP does more often what it's name sake implies, Grand Touring, so high increases in NVH are a no go for me. That was one thing I HATED about my Ecoboost Mustang. That 2.3 TDI engine was so darn clanky and coarse feeling compared to the Coyote 5.0, which just purrs smoothly all the time...half the time I thought it was going to blow up in my face lol (never did, but makes the car less enjoyable to drive).
I see you offer Poly vertical links for 1/2 the price of the delrin ones. I was thinking this might be a good compromise on the vertical links over the factory ones for a street car.
I have a 2016 Ruby Red PP GT now (gotta update my sig still from the 2016 Ecoboost I had). But it's nearly bone stock save the Corsa Cat Back it came with, window tint and my RTR Tech 7 flow formed wheels I kept from the EB.
Given the rather substantial bump in power, I don't feel the engine is the first place to look on a PP GT, but rather the suspension to best make use of what's already there.
I'm looking to address the biggest culprits of wheel hop other than the diff bushings. I did poly bushings on the EB, NEVER again on a street car. As I said before, it sounded like a bowling ball was rolling around in the trunk. Just not acceptable for a daily driven street car, so that leaves the IRS.

Also I see three different types of Delrin links, two is spherical bearings, one without delrin inserts: https://www.bmrsuspension.com/?page=products&vehicleid=24&maincatid=113&catid=416
What are the applications of each? I am presently leaning towards the Poly ones for $99 as it's a street car that sees occasional drag and somewhat frequent Auto X (which I enjoy much more than drag most of the time). The rear end of a PP car is what needs all the work, the front end already has spherical bearings on all the linkages save the strut mount and the solid rubber on the main rear link where it attaches to the chassis (but given it's a solid rubber core there's little give). The front end on these cars feels laser precise from the factory, the back end is a whole new ball game of nothingness and squishy hippie love....
