How much rr shock angle inward would be too much?

[Kojak_9x]

Someone correct me if I'm wrong but I've always been told no more then 10*, might be safe to 15* but when you get it at too much of an angle it will change the ratio of the shock due too much angle.

I'd like to learn more about this too. Anyone?

15deg is common, you talking just shock or coilover too, if coilover that's when you
Need to pay attention to how far you lay it in or you will soften your bump travel rate but again 15 deg is common.

[Hagen14t]

How far would you dare go in? 18*? Doesnt this help to keep the car from skating?

[racinjj]

Keep in mind that as the chassis rolls the right rear upper mount actually moves toward the left adding angle. I would say no more than 10 degrees.

Mark Bush did an extensive article about Motion Ratios in Dirt Mod Magizine a five or six issues ago.... I will look up the date on my copy.....

Johnny, that would be great. Let me know if you can find it.

It's the one with Hughes on the cover. 15* is what my car had in it and I see plenty of cars with more than that.

15* comes out to .93 spring rate multiplier.

So your 175 spring comes out to a 162.75 spring @ 15*. 175*0.93=162.75

How could i find one of them?
