ls1.com it is a company on ebay. I ordered their double diamond subframe connectors for $140. The install was easy as pie, it fit like a glove. And right after the install I could tell a difference. I highly recommend this company.
I just ordered lower control arms for $79 and a strut tower brace for $56 from them yesterday. I will keep everyone informed on how the install goes and the performance felt on the good old butt meter.
