DHL may impose a $15 USD surcharge on orders where the custom duties are not paid within a reasonable time. If you refuse shipment during any attempt by any shipping carrier used, you are implying implicit consent agreeing that you will incur a 20% restocking fee to cover return shipping costs, taxes & other fees imposed on Numeric Racing. **We do not mark down values or send as commercial sample, it is against the law***

Common Questions

Q: I recently acquired a short shifter for Porsche 718, 981, 991. I noticed that you offer two spring options. What are the differences? If I choose the 2mm spring, can I swap it for the 1.5mm spring?

A: The 1.5mm mimics the GT4 stock shifter. The 2mm gives you an even more stiffer shift. We do not swap springs. The 1.5mm is the default spring, 2mm is available only by request.

Q: I recently bought cables and the cable ends are black and look like plastic.

A: We assure you that Numeric Racing has eliminated all plastic from the cables. What you are seeing is black plating (anodizing), which strengthens the metal pieces and provides corrosion resistance.


We can work with you to make custom cables. Please email Dan at Dan@numericracing.com for prices/specs.

Q: Do you sell shift knobs?

A: Not at the moment, but we may decide to produce weighted shift knobs in the future. Numeric Racing shifters are direct-replacements. This means that you can use the shift knob that is already in your vehicle.

Q: I have an older Numeric Racing adjustable shifter. It has a bronze pin, unlike the one that you have advertised on your website. Does this still carry a warranty?

A: Yes, we have a limited lifetime warranty on Numeric Racing shifters. It covers the original owner only. The warranty covers parts used for that model shifter and not for the currently revised shifter. If you would like to upgrade your shifter to the latest version, the upgrade fee is $99. The customer is responsible for shipping charges.
