MX5/Miata ND Seat Lowering Potential

Optimizing Seat Lowering in the Mazda Miata ND: A Comprehensive Guide

 

• Removing Seat Base Tensioners:
  • Reversible, quick, and easy.
  • Minimal lowering effect.

 

• Lowering the front of the seat base by detaching the height adjustment rack:
  • Reversible, quick, and easy.
  • Effectively allows the body to "dive" forward for increased headroom.

Remove side bolts, pull the front frame outward, disconnect the rack, and reassemble. Seat front adjustment will be fixed in a lower position.

• 

  Safety Note: This mod should ideally be paired with significant rear seat lowering to maintain the seat's angle and prevent forward body slippage in an accident

 

• Removing Seat Backrest Tensioning:

• Reversible, quick, and easy.

• Allows the body to lean further back (approx. 80mm), providing about 20mm of perceived headroom.

​Significant improvements in space and support.

 

• Trimming Foam Around Seat Back Side Supports:

• Non-reversible, effective, and cost-effective.

• Improves ergonomics for taller drivers. Taller drivers have considerably larger chest and this is actually a MUST for anyone using the 58mm lowering rails or fixed adapters.

​Carefully trim foam from the inside of side pads to maintain the seat's shape. Provides a sport seat feel with the above mod.
