Looking for similar info and have reached out through PM's to a few members. I currently have a pair of Superflex that I want to use with Bilsteins and one of these:
OME 884
Toytec 521600
Toytec 112-620
Top plate spacer (1/4" or 1/2") for 3" total??????
No added weight on the front and looking for a "softer" ride as this will be for my wife's.
An older thread has the spring rate percentages greater than stock for OME's and rear Toytec (Superflex) only. I am unable to find the spring rate percentages for the Toytec 521600 and 112-620. Toytec's website states 620 lbs for each set but the 521600 is listed as HD. Is this due to longer length? Since the same 620 lb rating, will they (521600 nd 112-620) ride the same but one with less lift due to length of coil?
I found info that states OME 884 has a 590 lb rating so I assume this won't be as stiff as the Toytecs.
Not sure this helps with what your looking for but hopefully someone will chime in.
Also, maybe change your headline to be more specific i.e. "OME 884 with Bilsteins help"
