Learn how to install JDM Hand Steps on your Mazda RX-7 FD3S. This guide covers surface prep, adhesive placement, and common fitment pitfalls.

Quick answer

Installing JDM Hand Steps on your FD3S is a straightforward process that requires careful surface preparation and positioning. The neoprene steps attach with body molding tape and need to be aligned correctly before the tape sets.

Why fitment matters more than you think

The FD3S door sill has a subtle contour that varies slightly between early and late models. If you place the step too far forward or backward, it can interfere with the door seal or look misaligned from the driver seat. A dry-fit test before peeling any backing saves you from a sticky mistake.

The OEM originals used a flexible rubber material that conformed easily. Our version uses waterproof neoprene with a stitched edge, which is more durable but slightly stiffer. That stiffness means the step won't stretch into position — you need to get the placement right on the first try.

Installation steps

Clean the door sill thoroughly: Wipe the sill with isopropyl alcohol to remove wax, oil, and debris. Let it dry completely. Any residue will weaken the tape bond. Most adhesion failures trace back to a greasy surface. If you've recently applied vinyl protectant, strip it with a degreaser first.
Dry-fit the hand step without removing tape backing: Place the step on the sill in the approximate position. Close the door gently to check clearance. Adjust until the step sits flush and the door closes without rubbing. Common mistake: positioning too close to the door jamb, causing the step to lift when the door is shut. Leave a 3–5 mm gap from the jamb edge.
Mark the final position with painter's tape: Use a piece of tape on the sill to outline the step's front and rear edges. This gives you a visual guide so you don't second-guess yourself after the adhesive is exposed. Skip this step only if you have a second person to help you align while pressing.
Peel the backing and press firmly into place: Remove the tape backing from the step. Align it with your marked guides and press from the center outward. Apply firm, even pressure for at least 30 seconds across the entire surface. Don't peel both strips of tape at once — expose one side first, position it, then remove the second backing. This prevents the step from folding onto itself.
Let the adhesive cure before using the step: Leave the door open or tape the step in place for 24 hours. The tape reaches full bond strength after a full day at room temperature. If you close the door immediately, the seal can push the step out of position. Use a small clamp or a heavy object to hold it flat during cure.

Mazda RX-7 [FD3S] JDM Hand Steps: Our version is cut from waterproof neoprene and we stitch the edge to give it a nice finished look. The stitched neoprene won't fray or absorb moisture like the original rubber, but it also won't stretch to cover misalignment — so careful placement is critical.
