Not sure if I should have this as an issue per se, but here are my notes on the calculations. If I'm completely off please tell me!
Stock Springs (Nm/mm)
F: 44 (250lb/in)
R: 26 (150lb/in)
AC Civic Baseline (suspensions.ini
) (assuming it's using the same spring rates as above):
(F) SPRING_RATE=55000
(R) SPRING_RATE=35000
New Spring rates (which DJ/AEH crew will be installing):
F: 96 (550lb/in)
R: 88 (500lb/in)
Looking at the front, dividing the sprung value (55,000) by the stock springs (44) gives a multiplier of 1,250. If we then use this multiplier (1250) by the rate of the new springs (96), we get a value of 120,000, which could be used in suspensions.ini: SPRING_RATE=120000
Respectively, the rear would use SPRING_RATE=118448
given the 500lbl/in rear springs.
@djhedges - cross-check me here.
I spoke with Markus on the phone a minute ago and he said the only way to properly calculate spring weight is to measure the suspension geometry, but even having those measurements it's not a simple calculation given non-linear bits of the suspension. However, if we can use the values above as a baseline, we should be able to pull suspension travel data from telemetry and validate how off we actually are. (that will definitely need our friendly engineer's help for said analysis)
