"Mod" means something different to a Tesla owner than it does to a Civic owner. There is no aftermarket ECU tune, no exhaust to swap, no spark plug to upgrade. What we can change — and what actually changes how the car drives, hauls, and ages — lives in three places: the things that bolt to the body to absorb wear (spoilers, bumper guards, mud flaps), the things inside the cabin that fix factory ergonomics (behind-screen trays, console organizers, dashboard mats), and the things that protect the high-replacement-cost surfaces (paint, screen, door sills). This collection is BASENOR's curated short list across all five current Tesla generations.
What counts as a "mod" at BASENOR
We split everything we ship into two engineering buckets, and only the first one earns the mods label:
- Engineering-grade mods — reversible, no-drill or factory-mount-point installs, fitment validated against a measured reference vehicle (we keep a 2024 Highland and a 2025 Juniper in-house), and tested against a stated load or wear scenario. Examples in this collection: the Highland Gen-2 rear spoiler (3M VHB factory mount, no paint penetration), the no-drill mud flaps (held by OEM wheel-arch hardware, removable in under 5 minutes per side), the carbon armrest organizers (drop-in, no adhesive on factory leather).
- Cosmetic accessories — sunshades, phone mounts, floor mats, regular wireless charging pads. Useful, but they don't change how the car behaves. They live in their own broad collections, not here.
Warranty-safe by design
Tesla's New Vehicle Limited Warranty (4 yr / 50,000 mi basic; 8 yr battery & drive unit) doesn't get voided just because you installed an aftermarket part — the Magnuson-Moss Warranty Act prevents that. What does create a denial risk is damage caused by the part: a drilled fender liner, a melted dash from a low-grade adhesive, or a console organizer that blocks the emergency manual door release. Every SKU in this collection is engineered against that exact failure mode:
- No drilling on any exterior part. Mud flaps mount via the OEM aero-skirt fasteners; rear spoilers use 3M VHB on the trunk lid's factory mount surface.
-
Emergency-release clearance. Door-side storage boxes
(e.g., the Juniper TPE box, SKU pattern
basenor-juniper-door-tpe-*) are notched to keep the manual mechanical door release fully accessible — a real failure mode we've seen in 3rd-party boxes. - HVAC inlet clearance. Behind-screen 2-tier storage trays are dimensioned so they don't block the dashboard center vent or the cabin sensor under the screen.
How we test before we ship
Each SKU here ships only after passing the BASENOR test bench: a 200°F oven cycle for any part with adhesive (replicates summer cabin temps in Phoenix), a 50-cycle install/uninstall test for clip-on parts to confirm the mount survives buyer remorse, and a fitment dry-fit on the matching reference vehicle. We document the rig, the equipment, and a sample case study at /pages/test-method. If a SKU fails any of the three gates, it doesn't get listed — full stop.
Pick by what you want to fix
- "My paint is getting hammered by tire spray." Start with mud flaps (Highland, Juniper, or Model S/X — same TPE formula, different aero-skirt cuts).
- "The console swallows my phone every time I corner." Console organizer 4-PCS hidden (Highland/Juniper) plus the carbon armrest storage drop-in.
- "The trunk lid feels too plain / I want presence at the charger." Rear spoiler — OEM Gen-2 ABS, no drilling, matte or carbon-fiber finish.
- "My fingers can't reach the cup holder when the car is in motion." Cup-holder insert (Cybertruck or Highland/Juniper), reduces the well by 18 mm so a 32 oz Trenta sits stable.

- Tesla Model Y Mods — Juniper and 2020-2024 legacy, fitment notes and load tests.
- Model 3 Highland Hub
- Model Y Juniper Hub
- Cybertruck Hub
- Model S Hub
- Model X Hub
