PST Carbon Fiber Driveshaft



  • Q: 2019 STi fitment?  Hazuki-San 1 month ago

    In the description it says it fits the 2019 STi, however in the comments someone said it was a 1/2 inch too long. Can you confirm this one way or the other?

      A:  It's a perfect fit on the 15-20 STI, I'm guessing that particular reviewer got either the wrong product or a defective one. Thanks!

  • Q: custom order  chrisb_one2 years ago

    would I be able to order this drive shaft with the forged aluminum yolks vs the steel yolks? I'm concerned about the rusting from the steel yolks as someone else has stated.

  • Q: PST Carbon Fiber Driveshaft  eschellerup2 years ago

    I read online that the DSS CF driveshaft comes with larger bolts that hookup to the rear diff and a workaround is needed to make it fit with the supplied hardware. With the PST, is that needed or it a direct fit with supplied or with original re-used hardware?

      A:  Hardware is not included, this is intended to be installed the the original hardware on your vehicle and would be a direct install.

  • Q: Will this fit a 2015 STi limited?  edekeratry557954 years ago

    I am wondering why the limited isnt listed for fitment. Is there something substantially different that I dont know about that would cause this to not fit a 2015 STi limited?
  • Q: PST carbon fiber driveshaft   sti20154 years ago

    It has been suggested that the combination of a light weight pulley and light weight flywheel might trip a CEL. Will the PST driveshaft result in a CEL as well since rotational mass has been dramatically decreased? '15 STI
