I'm selling a set of M033 springs. I know they are the more compliant lowering spring (as compared to M030). But a member is asking me if they are "ROW." I believe there is only one M033, so I suppose it is ROW. Right?
Just wanted clarification so I don't misinform someone.
By default, M033 is ROW. US got taller springs for federal compliance and M033 was what everyone else got at the time for non-sport.
Ron is right - M033 is a ROW height by definition because Porsche didn't offer it here in the US.
This can be a bit confusing, and it confused me when I was looking at springs. Colloquially, we say "ROW height" a lot. The problem is that "ROW height" can mean one of two different heights. Which ROW height are we talking about in a given context?
1) ROW standard - default ROW height, lower that default US height. A ROW car with no suspension options.
2) ROW sport - lowered ROW height. A ROW car with either with the M030 "sport" option or M033 "lowering" option.
Let the record state that I'm going to keep using "ROW height" to mean "ROW sport height" not "ROW standard height" even though the OCD in me struggles with its ambiguity.
Here's a great summary post that explains all of this, including the part numbers for default ROW springs:

1- M032 - USA/Canada ride height (this includes USA M030 Sport option)
2- M029 - Standard ROW ride height - 20 mm lower front/10 mm lower rear
3- M033 - Lowered ROW ride height - 30 mm lower all-around *
4- M030 - Sport ROW ride height - 30 mm lower all-around
5- M002 - Carrera RS ride height - 50 mm lower all-around

I found this thread with Bill V's posts quite helpful. The MO33's with Bilstein B8's looked a bit high to me in front, but it's actually slightly lower than ROW based upon these ride heights from the prescribed measuring points. https://rennlist.com/forums/993-foru...de-height.html
