I am looking for anyone who loves or hates their suspension upgrade on a m45 so I know which method or brand i should go with and which to avoid! Im gonna be runnin on staggered 20's 8.5 up front and 10 in the rear. Any and all info would be greatly appreciated!

Welcome to NICO and the VIP Forum!

What are the offsets on the wheels? What size tires? All of this will play a part in lowering.

im pretty sure the offset is 45, and the tires are 255/35/20 and 285/30/20.

Ok, are you looking to go static (coilovers/springs) or air? Going to run camber, flush, or tucked? Fenders rolled, flared, or pulled?

Not trying to be crazy with you, just want to make sure we hit you with the right suggestions.

That being said, I prefer static. I have JIC Magic coilovers, yours can be found HERE.

Or if you want flare and adjustability, you could check out Air Runner.
