On a 944....What does the color code pink on the springs signify......hard..medium..soft?
Thanks.

KuHL 951

Up to 86 the 'red' dots, no pink, were:

1-dot.....2500-2560 N
2-dots....2560-2629 N
3-dots....2629-2698 N

Don't ask me for the metric conversion, I'm math dyslexic!

Thanks for that......there are 3 dots and look pink....later944 or 968?

Pink is just 'red' with a long history of exposure to the elements. I could not find pink in any spring code except the Barbie Special Addition 944

As KuHL says, there are no "pink" dots used by Porsche. Assuming that they are red dots, those are M030 springs off an early (1982 to 1986) 944, with a nominal spring rate of 138 lb/in. Spring rate for three dots is 141 to 147 lb/in. For comparison, the stock spring rate for a 944 or 951 without M030 is 125 lb/in.

The other colour they may be is purple. Purple dots indicate stock (non-M030) springs for a 944S2, with a nominal rate of 136 lb/in. Three dots indicate a spring rate of 140 to 147 lb/in.

Thank you guys, your replies have been a great help.

im still having a hard time getting over the fact that years ago someone told me stock n/a's had 140lb springs, and turbos had 160lb springs. Then to find out its more like 120 and 140!!!

The white/yellow dot springs are even harder to decifer after 20 years of weathering :-)

Sorry to jump in but quick question. KuHL 951 indicated a range of rates for each dot. Does that mean that the factory springs are progressive rate springs?

Dan, you are not the only one, there has been a lot of mis-info on this floating around on rennlist for some time.

The only real difference between a stock turbo spring and a stock n/a spring is the length of the spring. The rates are the same, around 125 lb/in. The turbo springs are longer to account for the extra weight of the car - so the ride height of the two cars will be approx the same (the heavier car will compress the spring more, so the spring is made slightly longer).

I have seen turbo springs advertised for sale, as an upgrade for a 944 n/a. Hopefully not too many people have fallen for this, since it will only increase the n/a's ride height (generally considered less desirable).


The 1, 2, 3 dot specs are tolerance groups. When springs are made, due to manufacturing variances, they do not all have identical spring rates. So they are paired, or matched by their actual spring rate (so the car will have approx. equal spring rates, side to side). Porsche separates the springs into 3 spec ranges, and paints dots on them.

One other difference between the Turbo and non-turbo springs. The later turbo springs are conical not cylindrical. Since they are smaller diameter at the bottom you need special perches. Ask me how I know :-)
