A Guide to The Best Lowering Options for Lexus IS350

Back in 2005, Lexus decided to continue their competition with brands like BMW and Audi by releasing the second generation of their IS lineup.

The Lexus IS350’s genesis was out of Lexus’s need to square up with the powerhouse’s kids: the BMW 3 Series, Mercedes Benz’s C-class, and Audi’s A4. Although it didn’t come out as equal with the three giants, Lexus cemented itself as one of the best alternative luxury sedans to have.

What keeps the Lexus IS350 on the pedestal is its handling. The handling feel is appealing for most drivers, even without suspension upgrades. That means once the Lexus IS350 gets its well-deserved suspension upgrade, it’ll have a much more desirable handling vibe that goes well with many demanding activities.

Among the best upgrades to get for a Lexus IS350’s suspension is a lowered ride height.

When lowering any vehicle’s ride height, you’re often left with two choices: a set of lowering springs or a coilover kit. We understand that it’s pretty challenging to choose between the two, so we’ve gathered the best of both worlds: all in one list.
