Advantages of aftermarket upper:lower control arms

How much of a friggin can you take from an accident that was the cost of using cheap suspension parts?
Agreed. However, the BIG question (as always) that needs to be answered (and rarely is) is, "What are the plans for your car?????" If you just want a car that will handle nicely, call @PST and get a complete Poly rebuild kit for the front and a sway bar. If you want more, go with racing type parts (tubular). I have PST rebuilt front end with a sway bar and NO tubular stuff, and I am VERY happy with how my car handles. Would I take it to any kind of a road race around pylons? No! But I see little sense in spending a bunch of money on suspension upgrades that are WAY beyond what you want or need.
