No problem but if you fight traction issues I'd look towards those first. Poly and performance generally do not go together.
Ya might not been able to read that so I highlighted it for you. There is a reason racing programs do not use those style of joints. A good quality heim joint will out last any poly, rubber, or roto joint. Plus they require less maintenance and will not bind the suspension.
The other sales person here has had the same heim joints in his vehicle for 30,000 miles and now running into the 8's. They are checked yearly and this is why we use the correct heim joints with our products.
I just posted that to show that if someone is having traction problems, it is more likely a geometry/setup issue than the fact it has poly. A street car will see no difference in performance other than the added NVH. If you're building a 7 second track car, yeah absolutely, rod ends are the way to go. But to say a bushing is the reason for a car not working is not an accurate statement
Not a 7 second street car just a 3xxx pound street car making 6xxwhp that we recently had to replace for a customer with heim/heim because he said he never wanted to go through this again that no NVH is worth the hassle. These bushings kept his car from working drastically. We offer poly suspension using all energy suspension bushings however we try to help people understand it is not the best choice for performance and these pictures indicate why.
As you can tell the force was pushing through the poly bushing itself eventually making it fail.
Yep, that's what happens when you use a petroleum based grease with polyurethane. It dries and splits. I've seen bushings last 10+ years with proper grease, even behind 600+whp
