b15 spec V (or any trim for that matter) front springs

Just got an offer for spec V front springs on Facebook. I am looking for stock springs and the guy that offered said same size but stiffer spring rate. Can anyone confirm b15 front springs working?

I think the stock S12 front springs are in the 110lb/in area, no idea on the height. Spec V front springs are 154lb/in, also no idea on height or coil diameter.

Only one way to find out.

I do recall something about B13 springs, but I wanna say they won't fit.

S12 springs are 6" diameter, couldn't find any info on B15 spring diameter.

we'll see. Seller is going to measure them and mount them on his car to see how it goes. If it works, then we have another option haha.

 I can't just buy and try because shipping to Hawaii is like $60-$100+ for a pair our springs. Sad my life haha
