bilstein pss coilover?
 

I've read some specs on the bilstein pss coilovers. I wasn't able to find any info on whether or not it has a preload adjustment separate to to the ride height. any help would be awesome.
thanks

No it does not, the spring perch is your height adjustment.

With the progressive rate spring it should be under pressure unless you go past it's advertised adjustment range, iirc about 35mm lower than stock.

imo after messing with some of those 'separate height and preload' coilovers I much prefer the simpler mechanism.
