Marv, lots of guys on here (incl me) have HDs with M030 springs. This gives a better shock absorber and slightly stiffer springs. Going to RoW M030 springs also gives a lower ride ( although note that the HDs themselves offer ride height adjustment). This is a great setup for mainly street application. I think most PSS9 owners would agree it is too stiff for street only. There is lots of discussion on this. Dr. Calvo would remind you to do a search.

Now to get technical on you...

Turbo and RoW M030 front springs are pn 965.343.531.01.504. I have a brand new set of these.

Turbo rear springs are pn 993.333.531.16.504. I have a set of these that are used. AFAIK there is month difference between RoW and NA for turbo springs.

RoW M030 rear springs are pn 993.333.531.11.504.

There are several sources for full packages of springs/shocks/swaybars. I suggest you read up on the various options and make all your changes in one shot.

Good luck!

I have a set of M030 ROW springs that I bought from viperBob about a month ago - I installed them alone with Bilstein HD but did not like the ride quality on rough roads - so they are off the car after about a week and i will be happy to sell for half of what i paied for them.

Bilstein HDs you can get from Shox.com - they have them in stock for $1099 a set.

I just sent you an email.

Paul & Axlerod - you both have PM's to place me in line behind Marv for a spring set: So Marv - the ball is in your court - not that I'm pressuring you
You will like the Bilsteins - probably like the PSS-9 even more, but I've never had the opportunity to try them.

BTW, my HD's have the short threaded section - but my local, friendly machinest will lathe cut the additional threads for a few bucks: This may be a reasonable option for anyone wishing to further lower the fronts with a variety of spring options.

Oh, the pressure is on!

One more question, if I use the ROW M030 springs and do not use the HD version shocks, what will be the car's ride height compared to a stock US ride height?

What is a good target height to lower the car for street use?

Interesting idea of turning the threads on a lathe! I hadn't thought of that, but my thread cutting still isn't that great, so letting a pro do it would be better.

The two following links will help if you haven't already read them - both are full of excellent data, and will give a comparison of suspension heights available with OEM components. HDs and the top end coil overs (H&Rs, PSS9 offer far more adjustability) allow you to play within these ranges.

I'd like to retract that statement. It seems that there ARE different springs for RoW turbo versus NA turbo, with the RoW being shorter, at least.

Marv

Thanks! I am trying to get ahold of Axelrod and see if we can swing a deal first, but if that falls through I'll let you. I'll let you know either way!
