I've been through similar machinations. BB's general front suspension: lower AND upper inner bushes should be the same, OE ones are good if you get the right shipment from China, Talk to your favorite supplier.
upper control arms should be the adjustable ones. Rear bushing in the trailing arm is OEM, front bushing there should be Poly; I've had solid aluminum for bunch of years. Remember the plastic pieces (top and bottom.
Alignment Should have as much inside caster as you can get. I've seen racers with -13 degrees - thats a lot but it tries to keep the front inside wheel on the track.
Poly bushes on the lateral sway bar are really good. I have an old Shankle sway bar that is thick as a big tree branch, with long welded end arms easy to drill a few holes if you need even more torque transfer. Poly in the little top and bottom connection links.
Alfaholics has a front A-arm (big cast vertical piece with the wheel axel) that drops the geometry that are lowered to follow the lowering of most springs to correct bump steering. Or JRR will modify yours to whatever suits - call him to discuss. This helps keep the the front inside wheel on the ground as you roll over the track bump. you can even modify the idler arm similarly. Look at JR's pinned thread.
I find it interesting that all these changes actually improves street driving. Much of it is to correct the inside wheel coming off the track, and to correct a bunch of suspension geometry than happens when you drop the car with stiffer front springs.
Use poly on the rear swaybar too as above. I just took mine off (well I just disconnected the end links) because was best with a bit of oversteer (Red Robin's too, cold, too hot) (BTW it's a Shankle F/R set) set that happens, well from a lot of these changes. I like a bit of oversteer (tail slides out in a turn) to make faster corner exits. Too much will put the car thru the fence backward - oversteer puts the car thru the fence nose first. Both happen when you are going too fast, or off the magical "line". Oversteer is magically sweet making street corners but right in front of the Cop Car with his radar. Flashing lights! Bad weekend!!!
Oh, I forgot about shocks. OEM's suck. Lots of others are good. I have yellow Kony's on front set at middle, red on the rear set on softest possible.
