Default rear suspension thoughts for my 951

I currently have konis coil-overs in front with 275 spring rates.
which I am happy with for street use.

I also have LR 30mm front sway and LR 5 way adjustable 19mm rear sway

now the torson bars are upgraded to 28mm/koni shocks I really want to ditch all that and just get a set of coil-overs so I can adjust the car without the bars in etc.

first question is whats a nice match to the front 275 spring rates?

best place to shop for them?

lastly I understand all I need to buy after words is bushings correct?

600 to match 275 fronts sounds really high?

I was doing research today i thought around 400

To find the wheel rates using coil overs you use 92% in the front and 42% in the rear.

.92 x 275 = 253
.42 x 600 = 252

600 is a lot of rear spring for a 275 rate front, unless you are setting the car up for auto-x and want a lot of rotation...

Somewhere in the 400 to 500 range is going to be a more neutral match for the given front rate.

I just ordered a full set of koni coilovers from Jason at paragon and he told me that 300lb fronts go with 450lb rears for a balanced street setup.

call him and discuss your needs
