Honestly I'm not thrilled with the softness of the rubber as it feels like 40k-60k miles so even these can start to tear , but that's just a prediction. I installed them on my '97 Acura Integra sedan. When pressing the bushings with a portside freight press, I managed to slightly deform the rubber around the edges. It doesn't look like it messed them up much, but for my race car I'd probably go for something stiffer like a Hardrace or something. Ride quality seems a little better, but I do…
