All depends, coilovers like tien or progress will be around 1k. The deliver amazing handling, lowering looks, and usually adjustable. Guarenteed great all around. Lowering springs however, are a differnet story. Basically your putting a softer spring on your stock strut. If you live on a bumpy hill, i sugesst a whole coilover system. I have progress lowering springs on my 05 but i dont have lots of bumps or hills and dont bottom out alot. Tires/wheels really wont make a difference easier
