Pedders lowering spring rates found!
 

As Pedders USA is gone, I went to a UK Pedders site and found their springs 220032 & 220035 listed. Requested spring rates from them via e-mail.(see attached). Rates are 130# front and 433# rear. Sorry about the quality of the attachment.

Fixed attachment.

130 seems really low for the front. Never ridden on them but it just seems low compared to other manufacturers...

I remember they were stiffer then that, around 220+ for the fronts

130kg maybe. this is english pedders.

7kg is 450 lb springs fyi

To the OP can you please ask for clarification on the rates. 130 in/lb seems too low, 130 nm and or Kg is way too high.

Thanks,
Matt

130# isn't that low... mine are less then that. They aren't road performance springs though.

I assume you have a car setup for drag racing?

yep. its pretty light too. id expect a stiff road spring to be 200-250#

BMR lists their 1" lowering springs at 220 lbs front and 460 lbs rear. Maybe it's supposed to be 230, not 130 lbs. Could just be a typo.

Is what it is! lighter spring in front(but probably taller than other drop springs unloaded) and stiffer spring in the rear, equals much less understeer in a stock SS.

Doubt its right. Member near me had them after getting rid of the Pfadt springs. Said they were quite a bit more stiff

The springs are progressive, you can't really rate a progressive spring like that.
