Does anyone know the spring rates for these lowering springs for 3rd gen? These are progressive, right?

Also, any numbers for the stock springs?

 

It's right on Racing Beat's website....

front: 260 lb/in
rear: 212 lb/in

stock: ~240 lb/in
rear: ~200 lb/in

The RB springs are linear as well, not progressive.

 

'93 stock spring rates:

290 lbs (F)
210 lbs (R)

I know the '94 and '95's were softened up ... but by that much?

 

good point, I thought those RB numbers seemed a bit low....now that I think about it, I thought that stock spring rates were ~ 280/200. I know there is a 1.4 ratio in stiffness between the front and rear.

 

I recall only the shocks were softened on the R models, but not the springs?

 

I've had RBs and currently have H&Rs (progressive). If you autocross, go with RB. If you drive your car daily over rough roads, and do open lapping events, get H&Rs. The RB springs were too stiff for the daily grind, but were very responsive on the autocross circuit though, especially through the slaloms. The H&Rs take a heartbeat to settle.
