Spring calculator, ride high, sping rate/harshness...
Posted: Sat May 14, 2016 10:43 am
Once again a spring thread...
I've read many hours, but i should have done this bevor i've ordered my new springs.
A few month ago i started a thread about sping rate, bump stop a.s.o.:
lotus-suspension-f42/bump-stop-lenght-sprint-t34965-15.html#p238883
I was looking for (fast) road springs and got the advice from Kelsport that i should try the following springs:
Front: 150lb/in free length 9"
Rear: 125lb/in free length 10"
I did take this advice against the (correct) advice that i got from Rohan and other luminary's here in this great forum, now i have the following problems:
1.) the ride height in front is about 1" to low (adjustable shocks are fully up)
2.) the spring harshness is absolut to high, may be it's ok for a race car but sure not for road
Sumary i need the car in front more than 1" higher (adjustable platform should not be on the upper end) and a much lower harshness, in my opinion fast road seems in front 90 to 100 and rear 80 to 90.
The wrong advice from Kelsport got me that I have to informed myselve a bit more about springs, i made this (very easy) excel file for calculating the right spring, based on the fact which are give from the Lotus manual (load) and on the fact that springs have almost linear characteristics. Please let me know your opinions.
Thanks
Mario
