What do you guys think of lowering blockes as a cheap way of lowering your car

Wouldn't recommend them

Lowering blocks are pretty much a standard practice for lowering leaf sprung vehicles.

Long term though, I would be looking to get the leaves reset. Use the blocks to find the desired height, then take it to the where you get the leaves reset and tell em, thats the height you want to achieve.

Ive got the largest blocks you can get (unsure size) on my xg, they're fine, been there for years... They're not even all that low either...
But the leafs hang down out the back a bit, have to be carefull reversing against gutters.
Just keep in mind that you cant load it up as much anymore, half a metre of soil in my ute and I could barely get up tje driveway, and the guards scrubbed off the "bridgestone" lettering....
