Any problems using poly along with rubber bushings

I've been trying to get my front end aligned. After everything is set up and I drive it the numbers get out of whack. So after reading through many posts I took a really good look at my lca bushings and they are torn. This is my fault for storing the car with the suspension hanging for a long period of time.
Anyways, I have to replace the lower bushings, which were fairly new. I want to go with polygraphite bushings with greasable pins. I already installed the Moog offset rubber bushings on the uca's and I'm not sure if there will be any adverse affects of running the two different bushing materials. Any downsides to it?
Since, I have to tear it down, I also plan to upgrade to 1.03 bars, adjustable strut rods and a set of Bilstein shocks. Any other recommendations?

You shouldn’t have any issues with running the rubber offset UCA bushings with polygraphite lowers. It’s not even like those bushings they see the same forces, the UCA just stabilizes the top of the spindle, the majority of the weight of the car is carried by the LCA.

The rest of your plan sounds good! The greaseable LCA pins and adjustable strut rods are the way to go with poly LCA bushings. And the Bilsteins and 1.03” bars are a proven choice. Only other thing would be tubular UCA’s for more positive caster than the offset bushings will allow, but that’s not mandatory and could be something you do down the road too.

When I use the poly stuff, I use marine grease and lots of it, helps keep the squeeks away!

I've posted this before, but it bears repeating - check the sleeves and welds in the K frame for the lower arms. They like to crack.

Another thing to check when you have it apart- there are UCA eccentric bolts out there that don’t have the flat cut far enough down the bolt. With those eccentric bolts, even if they’re fully tightened, the UCA can still move around because the washers bottom out on the flats before they clamp the UCA mount. So if you have wandering alignment settings and you have replacement UCA eccentric bolts it’s another thing to check. More than likely it’s the LCA bushings being torn like you’ve already identified. But it wouldn’t hurt to check the K for cracks and look at the UCA bolts if they’re not OE.

Nothing wrong with it at all. In fact, I recommend it for a street car. Polys on the lower control arms and rubber everywhere else. The lowers support all of the weight. Sometimes, using all poly can transfer more road feel than rubber to some people. Never bothered me, but I've seen some complain about it.

Going to start on the tear down tonight. I'll be looking for cracks as I go. I didn't even think to look for cracks in the k-frame.
Thanks
