Springs force rating
« on: November 17, 2019, 01:23:00 »
Hi all,

I've read somewhere that the standard front springs are rated at 250lbs/inch (and 300lbs perform better).

Assuming this is correct would anyone know that the rear springs force rating per inch is?

Note everyone that I have all the spring specs from DaveB (thanks Dave) but they don't state force. There may be a way to calculate it from the table but I haven't worked it out yet.

I'm getting a set of springs made locally here in Australia and I only have my fronts to give them - don't have the rears.

I've trawled through the many springs posts  :) but not found a mention of the rears.

Rgds, Joe

Hello Joe. Not sure you ever received a reply on this so it may be OBE, but the spring load specs go something like this:
Stock 113 321 04 04 front ~ 253-256 lbs/inch
Stock 113 324 04 04 rear ~ 363-371 lbs/inch
compensating spring stock1 ~ 188-190 lbs/inch
compensating spring stock2 ~ 412-417 lbs/inch

I included the serial numbers because there are a few options for front/rear. Also, there are 2 options for the compensating spring.  I think these are pretty close, but use with caution because they are based on some calculations that I did based on the spec data (and a lot of forum trawling as well).  I think there are others on the forum that already have these figured out as well.
