Progress Technology VS Racing Beat springs

Postby tomybandit » Mon Mar 02, 2020 3:29 am

What is the main difference in these springs?
The lowering is the same. I see the difference in spring rates.
I'm looking for springs that lower the car minimally.
Use daily, sports ride,twistie roads, sometimes autocross.
Mazda MX5 NC 2006 1.8
I have Bilstein B6 shock
Which is the better for me?
Thanks ... 545NC.html ... -1366.html

We didn't have a hand in creation of the Racing Beat springs so I don't have any detail to offer there. We were involved in the Progress Springs getting designed and made and tested on our cars here, so those have my biggest vote of confidence.
