Quality product and very well weighted. Had a few weighted shift knobs but this is by far best one I've seen and received for a reasonable price. Fitment on FD3 spot on. Shipped to UK without any issues and fully tracked.

The quality of the knob and powder coating is excellent. Perfect finish. And the tall teardrop is heavy and feels great to shift with.
However, on my Miata, the knob didn't go all the way down to the shift boot like the stock unit. Leaving an ugly gap and raising the shift height.
This is due to the insert, or the inside of the knob itself not being completely threaded from top to bottom.
This isn't a deal breaker and can be remedied. you need an appropriately sized die to run the threading further down the shift lever. Then the knob will tighten all the way down to the shift boot.
Most times, additional work is expected when customizing a car. However, I've never personally experienced this issue with other shift knobs on other cars.
This doesn't detract from the overall quality of the product. But it should be known that additional work may be necessary for proper fitment to your vehicle.

Love billetworkz. Got one in both cars now. Prefect weight and sleek looks.
