A Guide to The Best Lowering Options for Lexus IS300

Dropping a car’s ride height is among the most loved modification a car enthusiast does.

Compared to other car modifications, you can instantly see the result when you reduce a car’s ride height: that sweet lowered stance is enough to make you grin from ear to ear, especially if you own a Lexus IS300, a timeless classic JDM car that looks great on lowered stance. 

You can reduce your car’s ride height in two ways: By either installing a set of lowering springs or a coilover kit. Both can do the job pretty well, but they differ on the additional benefits they give.

Lowering springs don’t offer adjustability settings like coilover; however, it’s cheaper and a great choice if you just use your Lexus IS300 on the streets. But if you’re a track-oriented car enthusiast, you should get coilovers.

The list below features the best lowering options that you can get for your Lexus IS300. Either you’re a casual car enthusiast who just wants to have a lowered car, or you’re a race-oriented adrenaline junkie and who requires superb handling and setting adjustability.

Whatever you prefer between the two, we got you covered. Check the list below to see the best lowering springs and coilovers for your Lexus IS300.
