Frequently Asked Questions

I noticed that you offer two spring options. What are the differences? Can I swap between them?

The 1.5mm mimics the GT4 stock shifter. The 2mm gives you an even more stiffer shift. We do not swap springs. The 2mm is the default spring.

Do you sell shift knobs?

Yes. Currently our Shift Knobs only fit our G-Body Shifter (901/915/930). We also offer an extension piece to reduce the force required to shift. Within the coming months our shift knob will fit all year Porsche's!

I have a previous generation Numeric Racing adjustable shifter.  Does it still carry a warranty?

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.

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

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.

Can I get custom cables made?

We can work with you to make custom cables for just about any build. Please email Vlad at for prices/specs.
