2019 LM Rear Window Braces

The 2019 LM Rear Window Braces from FIVESTAR are engineered to reinforce and stabilize the rear window opening on 2019 LM platform vehicles. Designed for owners who demand structural integrity during high-performance driving, off-road use, or roll-cage installations, these braces eliminate flexing and rattling that can compromise aerodynamics, safety, and driver confidence. The predrilled design ensures straightforward installation without custom fabrication, making them an essential upgrade for both street and motorsport applications.

Manufactured from lightweight aluminum with a durable black powder-coat finish, the 2019 LM Rear Window Braces resist corrosion and weathering while maintaining minimal weight penalty. The slotted support flanges allow fine-tuning of fitment and clearance, accommodating slight factory tolerance variances common in production vehicles. Foam padding protects the window perimeter from contact stress, preventing cracks and seal degradation. At 1.83 lbs and measuring 38.25 inches in length, this kit integrates seamlessly into ABC NextGen chassis configurations without obstructing sightlines or interior access.

This rear window brace kit is ideal for 2019 LM vehicle owners preparing for track days, desert runs, or long-distance touring where chassis stiffness directly impacts handling precision and occupant comfort. Professional fabricators and enthusiast builders appreciate the predrilled holes and slotted flanges, which eliminate guesswork and reduce labor time. Installation requires basic hand tools and takes approximately 30–45 minutes per side. The black powder coat complements most factory and custom paint schemes, ensuring a finished appearance that looks factory-intended.
