Decent supplier for rear springs?

[themills]

Hi , I have widened the arches on my E30 and fitted staggered 9j front, 10j rear wheels.

I have coilovers on the front which are fine but the rear spring/coilover set up still left it too high so I have tried a few different springs and have settled with lowered corsa springs.

The height is spot on but the spring rate is off, im in need of a stiffer spring. Any suggestions of which may work better or a supplier would be awesome.

Cheers Millsy

Got a set of as new condition 325i Jamex lowering springs for sale for 50 quid if you want them

whats the drop?

[polsta]

60- 40 I think

[themills]

if that's 40 rears, I don't think its going to be enough, the ride height now is spot on with the front and that's on corsa lowering springs.

60 rears, don't think you could put any lower on and e30, they were too low for my liking hence being removed
