Will this interfere with my trunk seal or brake light?

This is a rear lip spoiler that mounts at the lower bumper area, so it does not contact the trunk or affect brake light function. Standard fitment uses factory mounting points without modification to lamps or seals.

Does this FRP piece require adhesive, or is it drilled and bolted?

This diffuser uses factory mounting points and hardware attachment — no adhesive required. Bolt-on installation at OEM locations ensures repeatable fitment and allows removal if needed.

Will a rear lip affect stability or create lift at highway speed?

A rear lip spoiler is designed to improve aerodynamic balance and reduce rear-end lift, especially at sustained highway speeds. This GT Competition profile enhances downforce without creating turbulence or instability.
