anyone know the stock spring rates front and rear in lbs?

 

I was told at Manthey Racing: 280 lbs/in linear / 550 lbs/in progressive.

996 Carrera: 146 lbs/in linear / 203 lbs/in progressive

996 Carrera with M030: 170 lbs/in linear / 260 lbs/in progressive

Manthey's suspension 340 linear / 980 progressive on KW DA shocks.

Combinations some tuners are doing with the Moton CS DA:

450/600 linear
530/680 linear (gtdrei runs this option)
600/800 linear (popular setup by a left coast tuner)
750/1000 linear (what I'm running)
600/900 linear (GT2)

The 04GT3Cup runs 1200/1500lbs. I know of a Club Racer running 1500/1800 on a Carrera.

TEIN GT3 kit: 1500/1550 linear

These are not precise numbers, more like round numbers. Give or take a few tenths.

 

Not surprised to see the rather low number ratios of the Manthey springs since they are mainly focused on setting up geometry for the Nurburgring and the track surface is all but smooth.

I'm surprised by the large difference in the F/R springs on the Manthey kit (340 Linear/980 Progressive). Does the kit also replace the sway bars ? Anyone on the board running this kit ? Care to post a review ?
