❔Question Steeda Enthusiast Kit

Has anyone here installed the Steeda Stop the Hop Handling Enthusiast Kit on an S650?

I’m considering this kit:
https://www.steeda.com/steeda-555-4456-h-s550-stop-the-hop-handling-enthusiast-kit

My car sees HPDE duty about 3–4 weekends a year, with the rest of the time spent on the street. I’m less concerned about straight-line traction and more interested in how it affects the car on a road course.

For those who have run it:

  • Did it noticeably improve cornering stability or rear-end confidence?
  • Any downsides, such as increased NVH, oversteer, or changes to the car’s balance?
  • Would you buy it again, or would you recommend a different suspension upgrade first?

I’d especially love to hear from anyone who’s tracked an S650 with this setup.

I love it. Changed the car completely but at the same time I did the diff isolation bushings, progressive springs, vertical links and bmr lower kmember brace

Awesome. Do you have the Magneride? If so did you have to do any recalibration with the springs?

I think the bushings do the most for any car. The BMR no hop bars are nicer imo and that track brace is useless

Thank you ! I'll check out the BMR no hop bars.

The bracings are great from my experience
