I have SSL on the front of mine and once settled it lowers about 40mm. I have lowered the back 50mm and it still sits a bit higher than the front. Although it looks great if I had my time again I would go 45-50mm at the back but only SL at the front. SSL is just that bit too low for driveways, kerbs and speed humps because the utes have such a looong wheel base. If you do go SSL at the front, dont forget a camber kit other wise you will wear out the inside of your tyres very quickly because of too much negative camber.
