The Tokico springs are an advertised 1.25 inch drop. (I'll let you know for sure when I get mine on )

 

Oh, and the Jamex springs are supposed to be 1.5 inch drop, however I can't find info on the spring rates.

 

ive got a pro kit on my car, now i just need my spohn stuff and i can post results

 

SUSPENSION TECHNIQUES HIGH-PERFORMANCE LOWERING SPRINGS

these are a 1" - 1 1/2 " drop spring.they lowered me firebird about an 1"

 

I think the reason they list two spring rates for the rear springs is because the twisting force of the drivetrain puts more force on one side of the rear than the other. Im not sure but it makes sense that one spring would be stronger than the other.

 

They're progressive which means they get stiffer as they compress. Those are what the 2 numbers mean.

 

And don't forget the rotation of the earth, driver's weight being all on one side, etc....

Actually he's kind of right, but most drag racers will use an airbag to preload the pass side spring to use the torque at launch to plant that tire harder on launch.

 

dropzone springs are a 1.75 drop. theyre available for all cars except convertibles. the part number is dzsp3100

 

keep info coming please

i was looking at the drop zone springs........i know they are cheap which means questionable. but i dont have much money. do yall have any feedback
yall could give me?

 

i have no problems with my dropzone springs at all. joined with kyb shocks and struts, i get a pretty good ride (for a lowered f-body ) and good handling.
