These are the GR86 and BRZ parts our own team has run, installed, and validated rather than simply listed. Every item in this category has been on a car we tested on the street, on track, or on the dyno. It is the shortest path to a build that works if you would rather not research every option yourself.

Yes. Tell us your vehicle, your goals, and what is already installed, and we will put together a parts list that works as a system instead of a pile of individual upgrades. Order matters as much as part selection, and sequencing a build correctly avoids buying the same part twice. Contact us before you order if you want a second opinion on a plan.

Under the Magnuson-Moss Warranty Act, a dealer cannot void an entire factory warranty simply because aftermarket parts are installed. A specific claim can still be denied if a modification is determined to have caused the failure, and ECU changes are detectable. Warranty decisions are made by Toyota and its dealers, not by LIMIT+1.
