What springs are these?

If i had to guess i'd say it had was 6" length not including dead coils, 90mm or 3.5" diameter, and a 230lb spring rate. Of course i could be completely wrong. Different companies uses different #s

The guy I picked them up from said they were H&R's. Maybe an old model or nla.

Racing Dynamics it looks like.

here they are next to H&R races and stock springs. They are definitely softer in the front the rears are almost identical.

Racing Dynamics it looks like.

That would be my guess also.

RD's definitely.

I have Racing Dynamic Springs, the green is darker on mine but the design (progressive spring, sometimes called dead spring) seems similar.

Definitely not the right color green for RD springs.

There going on my 318i hopefully there not too soft.
