Are the M030 on this chart the ROW that was used on the 965? Also, where does the adjustable come into play.
Thank you

IMHO I think it could be a brilliant solution to H&R's too-low F-R ratio

Hi
the list of spring rates by KW is quite long and in newtons ( x 5,7 to lbs) on their web site , front rear and helpers ,

Porsche Super Cup Racing Suspension for 964 - Do they come with adjustable camber plates for the top mounts ?

Are they too stiff for the street ?

I have Bilstein shocks with red Gemballa springs on a -90 C2. They were installed by a PO. Does anyone have any information on the spring rates?

I know this is an old thread but the info hear was brought up on pelican.

The info posted I believe has some errors. the M030 springs are not progressive front and the rates are incorrect at least for the US. The spring rates on the M030 springs should be the same as the RSA and turbo. Although length of the springs are different for the turbo therefore different markings.

The info I had is this.
'
89-91 Stock F-158/R-189
92-94 Stock F-169/R-189
91-94 Option M030 F-169/R-263 (progressive rear, working rate)
93-94 RS America F-169/R-263 (progressive rear, working rate)
91-92 Turbo 3.3 F-169/R-263 (progressive rear, working rate)
1992 Carrera RS (European) F-247/R-440 (progressive front and rear, working rate)
1992 Carrera Cup USA F-247/R-440 (progressive front and rear, working rate)

Progressive Fronts and Rears, static and working rates
H&R Green F-190/255 R-220/265
H&R Red F-250/275 R-270/295

As you can see there are some differences. These numbers were posted and accepted on rennlist for some time can anyone share where the differengt numbers come from?

Also the supercup setup as I know it is no longer available. I know of a 3.6Turbo that got the last set of those and I wanted a set badly. H&R said NLA and the spring rates are different. I also have an issue with the performance street setup which I had never heard of. Last year when I was switching from the H&R reds to a stiffer setup, H&R told me that they didn't have anything stiffer at that time. Why they would offer a street setup with spring rates that stiff for street use I have no idea.

Also H&R has now changed their entire line. they have a sport, super sport and race spring instead of the greens and reds.

BTW anyone interested in a nice set of reds PM me.

@ Anthony

sorry I missed your post.
Do not remember because of the long time, but it was a looong search...
You' re surely right there might be some errors, but are you sure of those Porsche-springs rates? I thought I had correct values... at least here in Europe.
If you confirm your numbers, I'm ready to uodate the chart.


@ geordie

as for the KW rates, the first number refers to the helper (the thin spring).
Thanks a lot for the data about the Clubsport set.

No. Re the KWs, the first # is the rate in N and the second is the converted lb/in number. IMO, listing them side-by-side is very confusing to most people who look at the chart.

FWIW, I run KW V3s with custom spring rates in between the V3 and CS set-up.

???

are you sure...? I've never heared/read so...

GT TWO

So if the Clubsport are Front 340 and Rear 685 the are firmer than the stock RS but a way off a Cup Car.

Do KW supply firmer springs for the Clubsports or can I source something from Eibach which is closer to Cup Car spec?

Thanks
