[10/10ths]

…..I have a 2004 “50 Years of the 550 Spyder Edition” Boxster S that had the factory M030 sport suspension.

I just replaced all of it at 80,000 miles and 20 years with the ROW M030 sport suspension.

It’s perfect.

These are factory B4 struts.

I’ve run B6 type Bilsteins on a Miata I used to own.

I did lots of track days in that car and those were great.

I think if you do a lot of daily driving, the B4’s are better.


If you are REALLY a track rat, then get the B6’s.

Good luck.
