Finally, new shocks and springs for track car
Hello, I have been on and off another Porsche forum over the last few years. My '87 944T is a mostly DE car driven to and from the track. I am purchasing new shocks and springs for the upcoming season. My car has Charlie Arms front A-arms and 968 MO30 sways. My wheels are 8 x 16 fronts and 9 x 16 rears running 225 front, 245 rear tires (RA1). I am planning to keep but re-index the stock torsion bars. I am planning on going to all solid mounts/monoballs etc.
I have been ringing my hands for years over what shocks/springs to upgrade to but have decided I am not willing to pay for the high-end stuff on my old tired car. I am considering the Intrax RSA kit sold by LR vs Bilstein Escort Cup vs KW Clubsport. If anyone has experience with the Intrax Kit I would be very interested to hear how it has worked for you. If anyone has a good contact/vendor for the KW clubsport kit that would be helpful. The Escort Cup kit is probably option 3 as I am wanting to be able to dial down the stiffness of the dampers for the drive to and from the track. All opinions are appreciated but keep in mind that I am not planning to spend more than 4K for the camber plates/springs and dampers. I expect to pay more for the solid mounts and install/setup.

I'm running 245-45/16 all around with Bilstein Escort cups, 425# front springs, 600# rear springs (torsion bar delete) and Weltmeister swaybars. The handling is phenomenal. I also drive the car on the street, and it's not too bad. Not super comfy, but more than adequate unless on rough roads.
If you're running 225 front and 245 rear you would want softer up front or stiffer in rear to combat understeer, I would recommend 400# (or 425#) front and 650# rear.
I have not run much stiffer, and would suggest that this is pretty close to the comfort limit for a dual-purpose street-track car.

Thank you IanM. I am expecting to get a fair bit of positive feedback on the Escort Cup setup. The spring rate recommendations are helpful. I am hoping others will chime in on the other options mentioned above.
