I'm wondering what people think is the next weak link on the S550 suspension and GT350 in particular. I already have four point roll bar, HANS, six point harness (...ok I should get a fire extinguisher) so safety stuff is ok. A new DSC controller is down the road, but not right now. I don't want much increase in NVH so no solid bushings, but what incremental suspension improvement next? My GT350 TP will will soon have 19x11"/305-30 & SC2s all around for track duty. It already has: R springs & rear anti-roll bar Two point Steeda front brace (which I think eliminated some front end shudder at max cornering) Camber plates with track alignment Poly cradle and diff bushings insets/supports are mentioned often, but I'm unsure if the GT350 bushings are as soft as the normal Mustangs. I assume both should be done at the same time or you might overload the ones not upgraded. Are these the next logical step, something else? Ideas? Thoughts on Steeda vs Cortex vs ?? for this, or some other item?
