ETi Mazda RX-7 (FD3S) Titanium Wheel Studs 55mm

Product Description

ETi Titanium Wheel Studs 55mm — Grade 5 Ti-6Al-4V conversion studs to replace OEM bolts with stud + nut setup. Standard 12x1.5 thread, 55mm length. The hardware change that simplifies wheel changes and drops rotational mass.

Key Features

• Grade 5 Ti-6Al-4V titanium — aerospace spec, full strength rating.
• M12x1.5 thread, 55mm length — standard JDM spec.
• Direct OEM bolt replacement — thread into factory hub, retain wheels with lug nut instead of bolt.
• Significant rotational mass reduction versus steel hardware.
• Pack logic — a 5-stud pack covers one wheel; a full set of 20 does the complete car (5 lugs × 4 wheels).

Why Upgrade

Stud + lug nut is faster and safer for wheel changes than bolts — align the wheel on the studs, then thread the nuts. No fumbling with cross-threading bolts at the track. Titanium drops rotational mass at every wheel, which translates to acceleration, braking, and steering response gains.
