After numerous requests for a spring upgrade package for the 987 with PSS9's, MGC has put this kit together with the most popular springs rates.

A perfect combination for hot street or track use, the 450/500 spring rates will reduce body roll and improve suspension response.

We chose Swift springs for this kit because they are the lightest, strongest, and highest quality springs on the market today.

The adaptor is made from aircraft quality 6061-T6 aluminum alloy for its high strength and light weight, and is anodized our signature red finish for corrosion resistance.

Together with rear helper springs, spacers and custom spring adaptors, this is a complete drop in spring kit.


  • Reduced body roll
  • Improved suspension response
  • Highest quality Swift racing springs
  • Complete bolt in kit

Each kit comes complete with: 2 Front 450 lb/in Swift main springs, 2 Rear 500 lb/in Swift main springs, 2 Rear Swift helper springs with spacers, and 2 Rear upper spring adaptors (hats)

The rates are within the Bilstein adjustment range without needing to be revalved. Other rates available on request.
