Suspension compensation plates

[jkish]

I'm getting ready to install the ROW M030 on my 2002 C4 Cab and noticed when researching parts that there are compensation plates/shims/spacers that are part of the strut stack. Looking at parts lists, there appear to be two different thicknesses of these plates available with the thinner ones about 3mm less than the thicker ones front and rear. I ordered a set of the thinner ones with the thought of using those to gain an extra 3mm of lowering all around if the thicker one(s) are already installed.

I know that these are designed to be installed based on the spring tolerance which is marked on the spring to obtain the "correct" ride height. I haven't found much information about the various colors that might appear on the springs and which plate or plates are to be used with each. My new springs have a blue stripe to indicate the tolerance batch.

I'm interested in finding out what others have found installed on their cars when disassembling the suspension for upgrades. A single spacer? A thick (6.5mm front, 4mm rear) spacer? No spacer?

Thanks for any info.

The tolerance color codes are different for front and rear springs and the code to use with your new springs is on the springs.

A = Running gear type code, B = Compensation part code

For (a Carrera) the front are:

1 white line = 3.0 mm thick compensation part

1 green line = 6.5 mm thick compensation part

A = Running gear type code, B = Compensation part code

For the rear:

1 white line= 0.5 mm thick compensation part

1 green line = 4.0 mm thick compensation part

Your front springs running gear type for MY02 C4 Cab with RoW M030 should be:

lilac/orange

No blue unless you have a C4S?

No C4S, just a plain ole C4.

My new front springs are lilic/orange and my rears are red/green. I verified the part numbers are what they should be for all of the components. The compensation stripe looked blue, but maybe it was actually a weird shade of green or maybe I'm just partially color blind or something :)

I looked at the springs again tonight, and there is no doubt that the compensation indicator stripe is blue, sky blue, on both sets of springs. I'm not sure what that means. Maybe there is a new indication?

Again, my car is an 02 C4 Cab 6spd

The front springs are:

996.343.533.25 Lilac/Orange with Blue compensation stripe

The rear springs are:

996.333.531.27 Red/Green with Blue compensation stripe

Any ideas?

Hmm... I don't know. Try measuring the thickness of the plate.
