its probably different for the SC300 but for my P10, it dropped it around 1.7 front and like 1.0 in the rear. the spring rates were pretty high i suppose cause it was pretty stiff, but im not for sure since i got it through my friend who got it from a shop in Texas. sorry i dont know the website for Espelir, ive tried looking for it in search engines, but its a japanese brand so youd have to look through jap sites. hope it helps
