Factory Spring Rates

[H2OSB]

Greetings--

Can anyone please give me the definitive factory front spring rates for both the 924 and early 944? I have seen both 110lbs/in and 140lbs/in for the 924 and both 126lbs/in and 160lbs/in for the early 944 (pre '86).

I have coilovers on my '74 VW Super Beetle made from 944 strut housings. I use 125lbs/in springs. I'm trying to get the correct strut inserts for my spring rate.

Thanks

I had, but I'm a VW guy, not a Porsche guy so it's difficult to be sure what sources are accurate. I've pretty much been told, at this point, 140lbs/in, is the correct value.

Thank you

for the rear of my old volvo . well it sagged. I had the spring rates, a sample, and the wire size. went to a spring shop and asked them to make new ones 20% stiffer... they have the speecial tools to form the wire and I guess probably a furnace for the amnnealing or tempering, they knew what to do.
I was happy with the results. I dont know how common "spring shops" are.. but it was less costly than OEM.

i owned a 71 superbeetle with mcphereson struts. god the thing was so worn out it shimmyd so much that I could hardly hold the steering wheel over 30 mph.. I rebult all the steering and problems basically continued until I changed the steering dampener..

at one point I adjusted the steering box and it came apart almost causing an accident, bearings fell out , all that shimmying must have broken the bearings up..

loved the car, the heating system sucked but it was fun. I changed all the interior parts, steering wheel, dashboard, window winders, knobs and such e-brake handle etc etc to brass and black walnut.. looked quite neat..

loved the traction it had on bush roads. I used to go speeding into big puddles and laugh as it sort of floated across, well one day I was up the mountain with a pretty girlfriend wearing high heels a dress, and here I got stuck in the middle of a huge mud puddle, I looked at her, she said no way lol.. took 4 hours to walk out and get a friend with a rope.. fun times.. ;-)

I compressed the springs with pipe clamps , carefully tying them down at each stage in case the pipe clamp slipped off.. crazy and dangerous.. worked but wasn't very smart.. later on my brother welded up some hooks with threads and threaded rod, that worked better..

I remember looking at the rear brakes, we laughed because someone turned them so thin that they separated from the drum so when I stepped on the brake there was nothing happening except that the shoes expanded against the outer "band" but it was not part of the back of the drum so no rear brakes at all..

the tach died and i or someone not too bright ran a wire under the car to the tach, well later it wouldn't run, but if I stopped it ran fine, was driving me nuts.. what happened was the wire from the tach got touching the axle so whenever I tried to move it grounded the coil and died.. then when out of the car, fan fine.. ;-) I pretty much rebuilt everything , painted it and sold it to buy a 63 international scout which was even more rough but just as much fun and twice as dangerous on the bush roads.. man that thing would climb like a goat with a 4 cylinder with so little compression when turned off it would "spin down to a stop" what it lacked in power it made up for with super low gears. still had almost no brakes.. ;-)
