While i haven't had problems with my Dorman UCAs, my car only sees track time a few times a year (granted, it's on the track for 7-8hrs/session).
I DO have experience with Raybestos Professional Grade strut assemblies... and it wasn't good. I used them on my 97 honda accord.
After <4 months of daily driving (100mi/day), they started squeaking severely. Raybestos via Rockauto.com did follow-through on the warranty (covering both the replacement part and the labor for replacement) but the replacement parts started squeaking again 3-4 months later. I ended up replacing the strut assemblies with KYB and didn't encounter any problems afterwards.
Bottom Line: I'd go with another brand besides Raybestos PG for strut assemblies.
