The general consensus from what I read was that the big thick shiny black Addco rear sway bar was out of production and no more. Well im bad at taking no for an answer and I wanted oversteer in a FWD car so I called them up. A really nice lady answered and after asking if they had any 639 bars in stock she walked to the warehouse and checked for me. Turns out they still have all of the jigs and stuff to make them AND had 4 or 5 just sitting there! They were missing a few bar clamps so she put them on order. I then officially ordered one from summit racing. A couple months later the backordered bar clamps showed up and they shipped me my bar! It bolted in with all of the factory mounts and everything! The best part? The long awaited bar clamps wouldn't fit on my car anyways... lol. Now combine this bar with my Doorman front sway bar, ZZP strut tower braces, zzp trailing arms, KYB GR2 struts, Saggy stock springs in the front, heightening springs / heavy load springs in the rear, and 245/50R16 Riken Raptor ZR tires on stock rims. The GMPP bar feels like a limp noodle in comparison and the rear end feels 10X tighter after swapping. I now have a grand prix that easily out-handles everything that has dared try to keep up with me on my favorite stretch of windy road. One mildly built cobalt SS even lost control and ended up flying off the road he was trying so hard to keep up. Still wasn't even close. Best part? It will now oversteer on occasion and I giggled like a little girl the first time it happened. Then I gave 3 different car buddies rides and they all had the same reaction. It feels so wrong that its just hard not to smile! Now who wants to see me enter a w-body into an auto X competition?
