Sounds like this is another Boxster you have now, not the one you put the M030 kit on? I also put the Suncoast ROW M030 kit on own 2003 S 5 or 6 years orlonger ago, it was on sale for $1,900 or $2,000 then. Maybe the Koni Sports STL-986 recommends, with some H&R lowering springs and a thicker front sway bar would do the same for less money. I can tell you that the part number on the rear sway bar in the ROW M030 kit from Suncoast was the exact same part number as the rear sway bar that was on my car from the factory, so you shouldn't replace that if you are buying separate parts.

And if it's helpful, I made this ROW M030 parts list at the time I bought my kit.
