These super sexy track rod ends from SPL are one of the only options on the market that are designed to allow for bumpsteer adjustment. They do this by allowing the tie rod end piviot to be relocated through the use of spacers. Reducing bumpsteer results in smoother steering response and better front grip.


  • Bumpsteer adjustable
  • Inner and outer tie rod end included
  • FK Teflon lined Rod Ends provide maximum articulation
  • Electroless Nickel plated hardened 4140 Chromoly tapered studs for precise fitment in the knuckle
  • Stainless Steel steering rack spacer allows for increased steering angle
  • 1/4″ (6.35mm) and 1/8″ (3.175mm) Stainless Steel spacers to fine-tune bumpsteer
  • Black Anodized CNC Machined 6061-T6 Billet Aluminum curved turnbuckle to maximize articulation
  • Made in the USA


  • Fits Mazda MX-5 NA cars with a manual steering rack. If your car has a depowered PAS rack, you’ll need the PAS-compatible kits.

Warranty information

Warranties cover defects in materials and workmanship only. Warranty is for replacement of a similar product, repair of the original product or refund of the purchase value only and excludes all labour and incurred charges including towing, fitting, inconvenience, and purchases of other manufacturer's products. The warranty is good for the period stated in the additional info tab from the date of purchase. Mileage warranties are for road use only and proof of mileage is required. Products must be installed by an independent experienced professional mechanic and the suspected defect must be present at the outset. The warranty does not cover damage caused by incorrect installation, failure to comply with the maintenance requirements of the vehicle, processing or otherwise changing the product, ordinary wear and tear, or any other external influences. Warranties are invalid if the product is used for racing, rallying, drifting, track days or any other form of motorsport or competition. Please refer to the manufacturer's own warranty documentation for more information.

Making a warranty claim

Proof of purchase receipt showing the date of purchase, proof of mileage at installation, proof of current mileage and invoice of the work undertaken by an independent experienced professional mechanic must be supplied along with the returned products for a warranty claim to be considered. If your vehicle needs to be used whilst your warranty claim is considered replacement parts from the same manufacturer should be purchased through BOFI Racing. In the event of a successful warranty claim, we will refund the card that was originally used to purchase the replacement parts, in full or in part depending on the nature of the claim. BOFI Racing reserves the right to make full or partial compensation at its sole discretion depending on the condition and mileage use of the returned suspect parts. For example, if you have used the part for several thousand miles before a defect is noticed, only partial compensation may be offered.
