A Quick Look at Demon Speed

Demon Speed information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Demon Speed is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

  • Typical reasons to choose these parts include moving to a more aggressive setup, improving response and styling, or replacing tired components with uprated alternatives.
  • Be aware that firmer or more focused parts can increase noise, vibration and harshness, and may accelerate wear if used hard without suitable supporting upgrades.
  • Watch for symptoms such as inconsistent fitment, new noises or vibration after installation, or rapid wear when components are mixed or incorrectly set up.
  • Consider whether supporting modifications are recommended for your intended use, and confirm compatibility before ordering.
  • Set expectations around comfort and NVH when choosing more track-focused components, especially on cars that still see road use.
  • After fitting, re-check fasteners and settings, and address any warning signs such as rubbing, knocking or uneven tyre wear.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Brakes — Brake components are renewed to restore stopping performance, address wear or upgrade a Porsche for fast road or track use. Common symptoms include vibration under braking, increased stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.

  • Check which Porsche models and brake setups a kit is intended for, and whether pads, discs and fitting hardware are included.
  • Follow the recommended bedding-in procedure and consider replacing discs and pads together if wear is significant.

Pin Kit and Guide Plates — Pad retaining pins and guide plates are replaced to ensure pads move freely and are securely retained in Porsche calipers, helping to prevent uneven wear and brake noise.

  • Confirm the kit is correct for your specific caliper type and whether it covers one caliper or an axle set.
  • Inspect old hardware for corrosion or seizure and clean and lubricate contact points appropriately during assembly.

Suspension & Axle — Suspension and axle parts are replaced to restore handling, ride comfort, braking stability, and safety, or to move towards a firmer, more controlled setup where desired.

  • Look out for knocking over bumps, uneven tyre wear, wandering, vibration, pulling under braking, sagging ride height or clunks during acceleration and direction changes.
  • Plan for an alignment after suspension work and prioritise diagnosing play and wear rather than replacing parts at random.

Wheel Accessories — Wheel accessories are replaced to improve security, correct fitment, and finish, or to refresh worn bolts, nuts, caps, valves, spacers and related hardware.

  • Check seat type, length and thread of bolts or nuts to match your wheels and hubs, and ensure spacers are hub-centric where required.
  • Use a torque wrench on wheel hardware, re-torquing after initial driving, and address any vibration or wobble promptly.

Centre Locking Wheel Parts — Centre-lock parts are replaced to maintain safe clamping and correct operation on centre-lock equipped Porsche models, particularly where cars see regular wheel changes or track use.

  • Inspect for loosening centre locks, clicking noises, worn mating faces, damaged threads or corrosion, and follow the correct torque procedure.
  • Use the correct tools for loosening and tightening, and recheck torque after bedding-in or intensive use.

Cup Stub Axle Centerlock Central Axle Bolt. This is a wear item and the threads will flow outward after continuous torquing. Don't wait for a failure!

demonspeed

Made from High Strength 4140 Steel Alloy Heat Treated.

After wear and tear has taken its toll on the center bolt, the threads can become deformed. This is an item that should be changed frequently.

The second and third pictures were taken of a used factory center bolt. These threads should be symetrical, but instead they are deformed 50% in the direction of the wheel nut. Deformed threads not only are a risk of failure, but they do not provide the same clamp load at the same torque as a non-damaged part.

Replaces factory part number 99633167190.

Fits: Porsche 996/997.1 Cup Cars with Centerlock Wheels

Sold Per Each.
