Jon, I talked to a guy at the STPR rally that was a NASIOC member. He said that upgrade made a bigger difference then would've expected. He had a 03 WRX wagon. He told me to look into it, but he wasn't sure if my MY already came with the upgraded piece or not. The guy also said because my car is a STI it might've already been upgraded too. Is that part STI specific? He also mentioned how you can basically take the stock peice and flex it in your hand. While the upgraded part is tough and won't bend easily.
