Street/Mostly Strip Front Suspension
Write a book. It still doesn't make them a good investment . Proven many times on customers cars that come here from shops that install them. All I have to do is put their cars on the lift . Point one thing out and I get a job reinstalling Factory style rubber lowers and struts. Put a piece of poly and rubber in a vise squash them both and see what happens,. LOL. These suppliers can sell Ice to and eskimo in the Arctic . They should hire you.
Yes, you've made it clear multiple times that you don't understand how to properly install a poly bushing, or what normal performance from poly LCA bushings on these cars looks like. Apparently your customers don't either, because your little parlor trick that has no bearing on how the suspension works when fully assembled convinces them to pay you to install inferior parts. Your little trick is literally a scam, so its ironic you make jokes about selling ice.
Just because you've been doing something the same way your whole life doesn't mean it's still the best way to do it. Technology changes, aftermarket parts improve on the OE designs, and things that couldn't be done with these cars 40 years ago are now common. But if you don't have a good understanding of how things work, and are unwilling to learn new information, you stay stuck in the past.
The OE bushings, no matter how well installed, will add resistance and binding to the suspension- it's literally how the OE LCA bushings function. Properly set up with aftermarket bushings and parts, you can get the suspension to move freely without having anything loose.
No doubt plenty of fast cars at the strip run OE bushings, that's fine. The OP asked about setting his suspension up so it had "freedom of movement". I gave him information that would let him do just that. He can do whatever he wants, and I'm not going to argue with a stump.
