Installing full ROW M030 suspension and just want to know what my options are for ride height. I know I can go ROW m030 height but can I go any closer to RS height with this setup without hurting any suspension components. Also can someone post pics of a 993 at ROW M030 height and RS height for comparison?

95 C4 993

Im between Sport and RS--135mm front, 117mm rear Not too low, not too high is the best way to describe.

RS is just too low...IMHO

ROW M030 height with 18" RUF wheels.

RoW SPORT here,




Seems like a good compromise. It's fairly low and though I wish the front was slightly lower the shop that did the work recommended against that and it's probably for the best, for my purposes (DD) anyway. I have bumped the nose on the ground just twice in a year, once by surprise and the other was just a bit careless and I "knew it was coming."

Yes, don't miss the last line of Mongrelcat's post with the link to Jeff's (InTheAir) Suspension Install for Dummies. I'm using it now replacing my orig. suspension w/ Bilstein HD's and ROW MO30's springs. FWIW I'll be setting mine at ROW Sport -10mm (halfway between ROW sport and ROW RS settings). I did the same thing w/ my previous '97 Cab. but I left it at ROW Sport.

Review Jeff's thread, it has all the setting info.

No options, just ROW ride height.
The rear shocks are non-adjustable.
you will have no choice on rear height.
The fronts are adjustable to achieve the 1* chassis angle, and for corner balancing. regards

Leland Pate's ( where is that guy anyway ? ) at RS height, my old Arena Red
C4S at ROW height.

In between RS and ROW with HDs and M030:

If you are using factory RoW M030 shocks, then just as geolab stated, you have no options.

Somewhere just south of ROW with Bilstein HD's and MO30 springs

Geolab brought up a good point. I assumed you were going to use Bilstein's for the shocks which give you adjust-ability both front and rear but if you're using stock ROW shocks they aren't adjustable. Which were you planing to use?

ROW Sport -10

Geolab is absolutely correct, w/ M030 struts and springs, I suppose you could use a different thinner top mount in back but other than that the rear is non adjutable.

Further keep in mind that there are 2 different M030 heights
US M030
front 174+/-10
rear 157+/-10

RoW M030
front 144+/-10
rear 127+/-10

RS
front 124+/-10
rear 107+/-10

OK, here's a question for the suspension gurus: The m030 springs were designed to operate at a specific ride height. I would imagine that operating significantly below that ride height could cause problems. For instance, the springs will compress a specified degree on a given load. If you go below the specified ride height, the car might hit the bump stops at earlier than it should.
To put this differently:
Lets assume, with the US setup, the car has 4 inches of suspension travel, before it hits the bump stops.
At ROW M030 ride height, the car would have 3 inches and at ROW RS 2 inches of available suspension travel (this conforms roughly to the differences in ride height).
Presumably, due to the difference in available suspension travel, each spring should hit the bump stops for full compression at the same load. Now, if you lower the car with M030 springs significantly below its designed ride height, it would hit the stops early.
So, is that a problem or has anyone ever experienced a problem?
