Hi. I'm in the market right now looking for lowering springs. Here's my preferred specs;
1.3" Front and 1.5" Rear. otherwise if not available, 1.5" both F and R will do.

Any suggestions as well where I can buy that ships Globally... Because I live in New Zealand.

Peace and have a nice day!

 

any. The softest you can get away with. Just make sure to cut the front bump stops about an inch NO MORE and don't go fast over sharp speed bumps or you will slam. Also cut the rear bump stops and cut the metal sleeve cup for the bump stops as well....or the metal cup will act as a bump stop and it's gonna make a clack sound in the rear if you bottom out. If you carry high loads. More than 250 lbs in the rear frequently get something with higher spring rate. Swift springs for ge8 are the softest. There's a list out there. Make sure you're looking at ge8 lowering spring rates not gd3. Cars gonna fly. Lowered car less body roll. As far as spring rates Remember lower spring rates = more grip softer ride. Higher spring rates less grip harsher ride but less risk of bottoming out.
