Yes, having your suspension at different heights side to side (with as much as a 1/2" difference) will contribute to a more unpredictable drive. Hopefully if they've settled at all then you should be able to get them all dialed in much tighter (closer in height) this time around.

Ok, so I decided to check my tire pressures today when I got back from lunch. It was a sunny day in the desert and it was in the mid 80's. I was surprised to see my pressures at 42 psi on every tire... I bled them down to around 36-37 since I had just driven on them and normally I check them cold. I figured they would drop another 1-2psi once I had them sit in the garage for a few hours. Just read them again and they are all right around 35 psi. Now that I got the tires at the pressure they should be I measured the ride height again. Here are my numbers:

After lowering Tires to 35psi / Tires over inflated (42psi)
RF - 26 7/8" RF - 26 7/8"
LF - 26 4/8" LF - 26 6/8"
LR - 26 4/8" LR - 26 2/8"
RR - 26 5/8" RR - 26 6/8"

I made the fractions in 8th's for easier comparison. The heights changed a bit once tire psi was adjusted to optimal limits as should be expected. Interested to see how the handling is now that my tires are not so friggin overinflated. I admit I took it for granted the tires were at 35psi when I had them installed but I never measured them myself. Thats my fault, but temperatures have been all over the place around here the past two weeks so the psi would have moved up and down to some degree anyway.

Still have a little work to do to try and even it up a bit better but at least the tire pressure has been addressed.

FWIW I always go over everything that's been done to my car when it's been done by someone else (that's why I always DIY when I can).

I think I'd leave the LF alone, match the RF to that height, and leave the LR alone and match the RR to that, then you'd have a final height of front=26.5" rear 26.625" that would be a nice setup IMO.

Or switch LF and RF because you have to factor in the driver's weight to achieve a better balance
#ghettobalancing lol that's the beauty of having coilovers is able to dial in to your exact liking
