SOFT Stiffness Bumpstop, length 58mm. Most popular with our stock class autocross customers because you can't change springs for stock class, but you can legally run these taller stops (which effectively raises spring rate legally). Stock class customers often use these in the FRONT, and the Medium stiffness 58mm in the rear, to help balance the car when using our large Racing Beat front sways (stock class allows changing just ONE sway, not both).
As used in our GWR bump stop kits but here sold individually so you can mix and match as you want. Can be used front or rear on all 1990 to 2005 Miatas, with all shock choices we offer.
