What to check before you buy

Before you hit purchase, verify these points so the kit fits and functions correctly on your car.

• Fitment & trim: Confirm your trim (IS300, IS350, IS200t and whether it’s F-Sport or base) — some kits vary by bumper style.
• Scope: Full kit vs partial pieces — full kits offer cohesive styling but cost more.
• Material & finish: Check if pieces are primer-coated, ready to paint, or shipped color-matched. “The kit is test-fitted … color-matched with base/clear coat, just like your OEM factory paint.” :contentReference[oaicite:5]{index=5}
• Installation & clearance: These kits bolt on in minutes with factory clips and screws. “It easily Bolts right on … with factory bolts/clips and support screws (all included)”. :contentReference[oaicite:6]{index=6}

Quick FAQ

Can I install only parts of a kit?

Yes — many owners buy a front lip or side skirts first and add components later. Just make sure the pieces visually match if you mix different sources.

What about F-Sport vs non F-Sport bumpers?

Check the product page — NIA clearly states compatible models and trims. If uncertain, contact their support before purchase.

Will this void my warranty?

Generally cosmetic bolt-on kits don’t void engine or powertrain warranty — but check with your dealer. Always install with reversible mounting where possible.

Final thoughts

For a 2018 Lexus IS, the best single upgrade from NIA is the full kit above — you get front, sides & rear in one cohesive set. If budget or daily use is more important, start with side skirts or a front lip and upgrade later.

Pro tip: Confirm your bumper type (F-Sport vs Base), pick the correct variant on NIA’s product page, and factor in installation & paint costs before you buy.
