Q: Who developed these sway bars?

They were developed with pro racing driver Randy Pobst and proven on record-setting UP builds, then validated on the street and in time-attack programs at Buttonwillow and Tsukuba. That is not marketing dressing; the settings and bar sizing came out of real competition development. What you bolt on is the product of that testing, tuned so a daily driver benefits from the same engineering that went into cars chasing lap records.
