Even if there were "bolt in" lowering kits readily available, the chanches that they'd be $500 or less are slim to none. Even the KYB AGX struts, which are not very good/proper, but are the closest off the shelf thing we have for lowering, cost around $500 new for a set. You can MAYBE find them around $400 if you're patient and really dig around for a bargain, and that's JUST your struts.
It's going to cost some money to get a decent sized drop, and to do it properly with quality parts that will last more than a year. If it were cheap and easy to do, everyone would be doing it.![]()
