My thought on this thing was that it might have the ability a tiny bit off the 60 foot via a crisper hit.
little help on the 60 foot always is worthwhile to an overall time slip.
BUT….. maybe it’s just a gizmo..lol
I won’t give you a ❌ on this but I do disagree on this statement. I removed my 1.98 powerglide low gear last year to calm my car down. My sixty foots were 1.25-1.27 and the car ran low 6.0’s. I installed a 1.80 and now my sixty foots average 1.30-1.32 and my car run low 6.0’s. I think I may have made one front shock adjustment this year instead of every track or seasonal weather change.
