where is a good place to start on spring rates? On a metric car it is a three link springs on top of the rear end.

I agree with the above especially if you have the metric lower a-frames. If you have the nova or camaro lower a-frames you may need to increase 100 pounds because the leverage is less as the springs are farther inboard on the a-frame. Start with the 650 and 750 and if is too soft you only have to buy one spring, an 850.

Wouldn't it also depend on the banking of the track. Doesn't high bank take more front spring?

I agrre on the 900 and 800 also the 200 left rear and 175 right rear are good. Use the conversion in the toolbox if you are running swing arms. I generally never changed the right rear but I would some times go as hig as 250 on the left rear when it got slick. Sometimes it worked and sometimes it didn't.

we ran last year at the beginning a 700/800 on left and right front, then went to 800/800, then 800/900, then 800/1000. And the last is where we left it. Car was rolling over on the front way to much, and had to stiffen. But, not ever setup is the same. PS: we also were running mono leaf springs on the rear.
