I've looked everywhere.

Basically, trying to deduce how the Hotchkiss middle setting (front) compares to BMR full stiff front. The percentages tossed around by vendors aren't necessarily clear on whether they're in comparison to FE3 or FE4.

i suspect HKS middle is close to BMR stiff, but want to run the dimensions through a calculator to confirm.

Ppl seem to like HKS middle and I want to make sure BMR stiff won't be TOO stiff.

Thanks!

Numbers from Hotchkiss for the front bar set in the middle is 65% stiffer and BMR set stiff is 69% if I recall correctly. Those numbers are compared to the 30mm 1le bar. The hotchkiss bar I have seen on this forum and measured and or other data could be less depending on actual bar thickness. For example, my bar is .233” wall vs the published .250. Not sure how much difference that makes if any.
Some like the bar in the middle for autocross, some like me like the bar set soft
As turn in is faster and less understeer.

Thanks.

That's a thick wall. Bmr is .188. do you happen to know the lever arm length?

No, but they are close and the adjustment holes vary depending on the mfg goals. there are several posts on here about sway bars and has arm length. The 1/4” wall vs a 3/16” for our cars is like being one hole stiffer hole to hole .
