I've bought both AMS and SZ expansion dp's (in that order). In my opinion both of them could be done better. The SZ is better for sure, but I was still surprised it was not top top quality. *flame suit on* In no way am I saying AMS is good or go buy AMS (the SZ set is on my car), but I was genuinely disappointed with the SZ one as well. FYI I had no problems with the MSP manifolds.

...Yup. I drive a Z now. |
