I know there's a couple of racers on here, maybe you can help me
understand why all the books and all the experts recommend a stiffer LR
spring over the RR?  They say do it, but never say why.

I always see stuff like:
LF: 1100 RF: 1300
LR: 200  RR: 175

The car is a Camaro on dirt btw (rear leafs)

Is the stiffer LR partly to compensate/work with the extra stiff RF?

The reason I ask is my Camaro came with a "helper" spring on the RR, and
now I'm considering removing it or swapping it to the LR.

Built in wedge. Also helps you kick the tail out when taking the corners.

It tightens the car up significantly when you get back on the
throttle.  The stiffer left rear spring gives you a crossweight
increase when weight is transferred to the back.  Thus the car can be
set up loose enough to turn well on entry and mid-turn, but hook up
and haul a.s with much less wheel spin when you are  pointed towards
the straightaway.  

I like it and run 75 lbs split.

thanks guys.  This sounds like this will help the occasional wild wiggle
I get coming off turn 4.
