Does anyone know if you can add gearbox Slik 50 to the rear dif & gearbox and center diff on a jap import WRX, it's just that as I understand there is a limited slip diff in the rear and a viscous type LS in the center diff, I have read that the rear diff is a mechanical type LS, will the Slik impair there operation. I have always been a great fan of Slik for both engine & gearbox but I know from my rallying days in a MK II Escort which had a clutch type LSD you could not use Slik in the diff.
