[Shotimes] Eibach springs with stock struts?

[Zach Leahy]

Ah, c eh?

either the speed of light, or just some random constant.  I think the
constant is more likely.  if you ctually had all the numbers for the
car then I could tell you what c really was.

For now, we will say it is the speed of light.  Why, becasue it sounds good.
