bump because I recently bought the strong-flex.edu bushing kit (from poland) for $271 +shipping and encountered a small issue. The outer bushing for the lateral links (pn:271211 per strong-flex) is too big! I am currently shaving all four of them smaller so they will fit.
Also... it was mentioned by TiC and YT in other threads but I just wanted to mention that the '05 STi lateral links are a direct swap.
