I've had the PSS9's on my car for about 15k miles

The WRX kit does bolt on, but there are some minor fittment issues and as the kit comes I would very strongly reccommend a few modifications while installing the kit. pm me for more info.

Ride comfort is very close to the stock '04 STi suspension, but handling is MUCH better, and the "bounce" from the stock suspension is gone.

Spring rates are one of the issues that needs to be addressed. The spring rates have to be changed a bit to better work with the STi's heavier weight and different weight distribution. The standard spring rates are about 400 front and about 350 rear.

The "bounce" from the stock sti suspension is very annoying...

What are spring rates with Kg conversion ?

and what new springs would you suggest with them ? stiffer or softer ?

The rates are about 7.1 kg/mm front and 6.4 kg/mm rear. I've run the car with several differnt spring rates, and stiffer front springs work much better.
