in that application i wouldn't think that urethane bushings will squeak. they should last longer, so try them and see.
see if these folks have something that will work, their bushing are graphite impregnated.

I do not plan on doing any track events in the near future.
The thing is that i have a de luxe polyurithane kit in the garage but if the bushings will squeak i will order rubber or polygraphite bushings instead
After i have changed the bushings and trailing arms to disc brakes i will have a shop do a 4 wheel alignment
Do not want to change bushings again after the alignment is done so that is why i ask about this now

Do yourself a favor and put in original style rubber bushings everywhere. That way you never have to change them again. You wont like the poly or poly graphite (which is the same, only black in color).

what about mixing them? on A body's they are putting rubber at the frame end and poly at the axle end and it is very quiet but the ride is excellent. down side is that two sets of everything must be bought in poly and rubber.

I will order rubber bushings for the strut rods
The only place i have used polyurethane on my car is a sway bar link kit with polyurethane bushings.
So far i have not had any squeaking from those

I installed Energy Suspension bushings throughout my car about 14 years ago. The stuff is still perfect and never had a squeak out of them. I would install them again in a heartbeat in any car.
But more than anything..I'd just install adjustable struts without the eccentrics to eliminate that trouble.

I just did a search and it looks like the kit is made of Polyurethane

The stock strut isn't adjustable, one mounting point is and that has limited adjustment. The adjustable struts do away with the stock cam set-up and make adjusting them more precise and there's no chance of adjustment change due to a loosened bolt or a slipped cam. On the street, I wouldn't say one is better than the other but in the high performance arena, the stock set-up is inferior.

As for the adjustable types not coming loose, please pay a visit to the C3 forum where this is the #1 complaint, despite double nutting, jamb nuts, locktite etc.
Of course this goes back to my first answer about not using poly bushings in a joint that needs 3D movement..........

The range of adjustment with stock struts and cam is more than enough for any car in good mechanical condition. It can be consistently set to the desired camber angle by any competent mechanic just as accurately as the adjustable type.

When you are dealing with a stationary anchor point versus one achieved through a cam adjustment that CAN be knocked out of position by severe shock you are better off with the stationary anchor point.
