Help! Car Doesn’t Feel Right After Coilovers, Wheels, and Tires
#11
I don't really think anything special is needed for the car to feel normal or safe. The car's alignment would have to be PRETTY badly out of spec to make it feel strange. Most of the time, the car drives fine even with questionable alignments.
I would focus on finding something really WRONG.
The alignment on the print out is close to factory spec. OP's got seemingly reasonable tires and...

Tires, tires, tires! And when you get tires, its a good time to get an alignment...

Thanks for all the replies guys. Just got a chance this weekend to work on it.
I started by checking tire pressure, I was at 35psi all the way around. I bumped that up to 40psi and the car felt horrible. Moving the wheel quickly back and forth driving straight was very delayed. The steering felt like driving a boat.
I backed off to 32psi all the way around and that feels the best so far, but still feels odd. I raised the back of the car up 1/4" also. I'm still rubbing on hard bumps in the rear. The shop that rolled the rear fenders didn't roll them all the way. I need to find someone local to finish rolling the rears and I can remove some more of the rear camber and fix the toe at the same time. Unfortunately I'm stuck with these tires but I'm thinking about ordering some Pilots and removing and selling these while they're still basically new. The car just doesn't feel totally stable, it's hard to describe. The steering is delayed, you input and it takes a beat for the car to get it. It drives totally straight and brakes straight though.

^^^Pilot super sports arent going to improve anything handling wise for you, they are still too flimsy a single ply sidewall like the tire you are on and will cause the car to sway and delay with steering inputs. You need a very firm sidewall tire on this car which is what it came with from the factory. Something from Bridgstone, like the s04 if your trying to stay in the max summer category, or even a Fderal 595ss is a great handling budget summer tire ive found. Anything in the extreme summer category will be a firm sidewall/good handler. Tires are usually the biggest factor along with alignment, but since your alignment posted isnt that out of line (other then not seeing what your front caster is) a better tire should be at the top of your list. Also when you change the ride height, expect your alignment to to be effected.

I thought that the Pilot's were the end all be all of street tires? They are listed in the max summer category also, like the S04s. I'm not really concerned with the cost so much as I am performance. I only drive the car a couple thousand miles a year so no matter what I get they will last at least a few years.

I don't really agree that pilots won't work for this car or that they were built around comfort. The steering input is quite sharp despite their 1 ply construction. I've been using the MPSS on cars for years now. The P4S is an improvement over the MPSS.
My complaint with the MPSS is that they tend to wander and tug at the steering wheel instead of feeling solid once they start to wear out.
I do agree that a tire with similar construction to the factory ones will be better for steering response. The S04 is a great option. Or BFG Sport Comp 2's.
I don't think that EP tires belong on any car that isn't going to see actual track use. There aren't any tires in that category that don't demand a LOT of compromise for street use. In my mind, their only use is for something cheap that can be thrashed at a race track.
Maybe the tires OP has are probably squirming too much. V12's have really tiny tread blocks.

If you have to run a lessor capable tire to gain more mileage and consistent traction all season, at least make sure its construction - primarily the two ply sidewall construction is in place to maintain predictable precise handling. If a member chimes in with a shitty vague handling S2k, which seems to happen about once a month, first question I ask is what tires are being used, and more times then not its a v12 or some other crappy max summer or all season with a single ply sidewall construction. Second question, whats your alignment.

After finally getting a chance to work on the car today, I took all the input from this thread and gave the car a once over. Problem solved and wow do I feel dumb. I didn’t remove the nuts from the top hats on any of the coilovers before I installed them! Fixed everything and took it for a drive and the difference is night and day.
