Door Sash System
Solid Profile Restoration / Series 1990—2005
Abstract
A comprehensive 4-piece structural restoration kit designed to replace aged, brittle sash covers. This solid-profile version removes the audio-specific housing in favor of the clean, factory-correct silhouette. Engineered specifically to resolve the chronic failure of mounting tabs on original 1990–2005 units.
Full Set: Left/Right Front & Left/Right Rear
OEM Fatigue Analysis
- Material Degradation Decades of UV exposure and thermal cycling cause factory ABS to become brittle, leading to surface chalking and structural cracks.
- Tab Fracture The primary mounting clips on OEM sashes frequently shear off during routine glass servicing or door card removal.
MITA Restoration Standard
- Reinforced Architecture Optimized tab thickness and proprietary polymer blends offer significantly higher impact and tension resistance.
- Factory Silhouette A 1:1 solid-profile reproduction that maintains the original design intent of the NSX cabin and pillar lines.
- Precision Texturing Calibrated leather-grain finish ensures seamless visual continuity with the factory interior trim and gaskets.
Installation Protocol (Full Set)
Remove existing front and rear sash covers using a non-marring prying tool to protect the surrounding paint and trim.
Recover or replace the internal metal spring clips (Part: 90615-SK7-003) if original units show signs of oxidation or tension loss.
Seat the clips onto the reinforced MITA tabs. Align carefully with the chassis mounting coordinates for the door and rear pillar.
Firmly press the assemblies until they snap flush. Verify the gap consistency along the weatherstripping for a factory-sealed finish.

I don’t plan on installing these anytime soon. I’m just hoarding parts. I will say that these are much better and sturdy than the OEM Honda piece.
looks close to stock. Good piece.
They fit perfect and delivered within a week of purchase. Thanks again
