Funny !!! I keep trying to raise the car !!!! We are tired of the scraping on the bad roads here in OK. I want it about 5/8 above the tires, running 315's on the front and 335's on the rear we need some clearance,we are running 18's on the back so it's low to begin with. you could go as low as you want with these !!!!!

just got back from another test run, drives a bunch firmer, I would guess the bushings would add to the firmness (plus the tires were up to 34 psi) ?? still not happy with ride height, back on the ramps !!! we are running Rival S ,,, 315/18 in front and 335/18 in rear !!!

Well, after our first AutoX event the Vette performed unbelievable !!!! we felt like in the turns we could be almost as aggressive as we wanted. never felt the Vette wanting to push or slide out, other than trying to control rear tire spin on a cold semi-wet track everything felt great !!!!!

Curious why poly bushings instead of Delrin or monoball?

Poly is usually a good upgrade over rubber bushings...initially. Only knock I have against Poly is that its prone to cold flow; meaning repetitive stressing in the same direction will cause the bushings to distort over time, as poly lacks the elasticity of rubber (ability to snap back to its original shape).

This will take a bit of time though, so again...you're good to go for quite a while. If this is becoming your track car, I would just say add these bushings to your routine track prep/inspections season by season to evaluate.

(Opinion piece) For control arm bushings, I will ONLY go with Delrin. The amount of stress the control arm bushings flex is very surprising...even with poly's. I ran them in my Cobra since about 25K miles (now with 75K miles) there is still ZERO noticeable deflection. And I'm happy to report that noise difference was not any harsher than stock. Given dynamat works wonders.

The problem with poly is that it binds, gets chewed up and needs servicing and replacement. So you skip poly and go to delrin, which is 100 times stiffer than poly and more durable. But if you are going to go delrin, you might as well go aluminum - which is ~30 times stiffer than delrin for the same approximate NVH as far as feel goes (most people can't feel the difference) yet is superior to delrin.
Straight from rubber to aluminum (monoballs) for me. Do it once and be done. No reason to go poly when there is delrin, and no reason to go delrin when there is aluminum. At least not for a car that is either raced or driven hard. You can debate it (cost, availability etc), but it doesn't change the facts.
By the way, this has been debated here for years and years (like our heads).

I wish Global West made their Del-A-Lum bushings for our cars. I'd run those in a heart beat...damn near indestructible. Ran their stuff on an F-body back in day...completely transformed the handling/traction/etc of that car.

No idea what this means. Did someone tell you that spherical bearings make a car "drive like a truck with 900 compound tires"? You certainly didn't test this yourself, as you would not have made such a ridiculous statement otherwise. Adjusting tire pressure will have more impact on what you can feel as compared to spherical bearings.
