What are the best parts for a Toyota Supra Mk3? The best Mk3 Supra upgrades start with universal-fit pieces that work on any build: a weighted shift knob for the notchy factory shifter, quality lug nuts, and fresh maintenance items like Motul synthetic oil. Because the Mk3 (A70 chassis, 1986.5–1992) is a 30+ year-old platform, most owners mix model-specific hard parts with universal accessories — always check each product’s fitment notes for your year and model before ordering.
The third-generation Supra — the A70 — ran from mid-1986 through 1992 with Toyota’s 7M inline-six family, including the turbocharged 7M-GTE. These cars are now full classics, and keeping one on the road is equal parts restoration and modification. Start with the basics: fresh fluids, solid shifter feel, and secure hardware, then move toward bigger plans like suspension refreshes and turbo-era power upgrades.
Popular brands in this collection include Motul for engine oil and maintenance, COBB Tuning and Hella for universal accessories, Muteki for lug nuts, and Gram Lights for wheels — plus JDMuscle’s own interior accessories built for Japanese platforms.

Supra Mk3 Parts FAQ
Will universal-fit parts actually fit my Mk3 Supra?
Universal parts fit by measurement, not by model — shift knobs by thread pitch, lug nuts by thread size and seat type. Most Toyota shifters use M12x1.25 threads, but confirm your specs before ordering.
Do I need a tune for these parts?
Accessories, maintenance items, and hardware never require a tune. If you move on to engine modifications like turbo or fuel upgrades, have the car tuned by a professional familiar with the 7M platform.
How hard are these parts to install?
Most items here are hand-tool jobs: shift knobs thread on in minutes, lug nuts need a torque wrench, and fluid changes follow the factory service procedure. Set aside 15–30 minutes for accessories.
Is there a warranty on aftermarket parts?
Most manufacturers cover defects in materials and workmanship — see our aftermarket parts warranty overview for details on what’s covered.
