Steeda 96-04 Mustang Clutch Adjuster Kit [555-7041] : Lethal Performance, Performance parts for Ford Mustangs

Do any of you have this? If so, does it improve shifting? What exactly is this adjusting, where the clutch engages?

I don't have one but thought about getting one eventually, I think the adjustability is to mainly keep the slack out of the cable. Probably could be used to establish a clutch engagement point also depending on how much slack you set into it.
