    You may want to make sure the lowering block is tight against the spring and perch. I had to drill my center hole out. The bolt that goes through all the leaf springs would not fit inside the hole of the block.

    Thank you. I wouldn't want the whole axle coming out from under me so next day off Imma use some thread lock and screw on a second bolt right after the first bolt and in between I'm gonna put a lock washer. Over board lol....

    Yeah same here I noticed the center hole was like a hair to small so I drilled it out a little bigger the first time I installed it.

    Wow that's way too low. That's how I had mine at first it was way loose just for regular socket wrench not even a torque wrench hahaha. On other Toyota forums they're saying around 90 but on other car sites there posting 150lbs lol. I don't know 38 seems so low and scared to torque it 150lbs and sheer the bolts lol. Toyota's specs are for stock u bolts though. I wonder if the strength and material is a lot different for the xii beilsten lowering block and u bolts. Imma just do 90 and put thread locker lectite and then a second bolt backing up the first and then a lock washer in between the bolts hahahah trying to make sure it doesn't come loose again lol

    Did you try contacting XII Performance and asking them what torque settings to use?

    How does this one lowering kit compare to the DJM as far as quality goes?
