I've got 2 Hyper flex kits sitting in my garage. I know its a pain in the ass to replace the stock ones but is it better in the end for auto x / road racing with the ES poly bushings in there? Or leave the stock ones there and hold out for spherical bearings and z32 uprights?

Are poly bushings better than spherical bearings for autox/road racing? I think we all know that answer, what are you really looking for? I'm installing the ES bushings now and the only thing I'm waiting to see is how much friction there really is in the suspension since that seems to be a big complaint on this forum. I'm sure its going to be a totally different car and I'll love it but I still drive on Philadelphia streets so sphericals would be crazy.-Ryan

Im saying i got these kits but after reading threads on this site about them im not sure if i really want to install them. Do they bind up or make more sticktion then the stock bushings? Would the car handle better on track with the poly bushings installed?SM 63 KA-t 470hp 480tq G30-660 A2W IC

I've installed everything but I haven't tightened anything down yet. I can see there will probably be some serious issues with some of the mounts. The spacers I've talked about aren't going to fit without bending the mounts so I was thinking of tacking in new mounts on the outside while the old ones are still in with the bolts going through all of them. Then cutting out the old ones, finish welding the new ones, and making spacers and using longer bolts. More work than most would deal with I'm sure but a quick MIG job will do and the outside of the poly busings won't ever rub.-Ryan

I did a complet ES kit on my S13 and it was a pain but the car's definately tighter now and not too bad on the street. If you want maximum gain for minimum effort I'd just get some subframe collars for the rear and replace the OEM tension rod bushings up front with the 3-piece ES versions. Those items are the biggest bushings on the car with the most movement. With the rear outer (knuckle) pivots being so close together you're probably not going to control compliance induced camber changes with anything less that a full spherical setup anyway.Don Johnson (really!)
Just so you know.
