Re: lift for 30x9.5 tyres
At one time I had a shackle lift and fit 30's. The shackles you want are 4 inches longer than stock, creating a 2" lift. The shackles are 6" total lenght. I run these with 3" lift springs and clear 31's, with a good amount of flex. The s/r would be better for approach and steering angles but if you have to recertify your Zuk, it may not be worth it. Plus you'd have to get new longer shackles for the rear on top of the s/r kit you refer to, because it only lifts the rear 1" and makes it look saggy. It just depends on which way costs less. Good luck.
