yeah, I wheeled a samurai with an add a leaf, lockers front and rear, and a calimini 4 to 1 t-case kitan 30 inch tires, for like a year, and ran circles a stock sami with a spoa, my only trouble was hangin my belly up alot, but i never tipped over until I did the rocky road 5 inch spoa kit, I have alot more flex now but i'm not really used to it yet i've tipped over like 6 times now, but I like not rubbing my tires and i like the ground clearence, hope that helps.
