How do I figure out which aftermarket spring to buy to increase the weight capacity of my vibe?I pull a small kayak trailer and about 500 pounds of gear in the back of the vibe and it is squatted pretty good.Ive looked online and reached out to Eibach but they do not make anything for it specifically but they have springs if I knew the spring rate/height.Would it be better to just fabricate a mount for a set of helper airbags?Any info would be greatly appreciated thanks
How often are you planning on towing and loading down the car with that much weight? Changing the springs to a higher spring rate will cause the empty ride to be much stiffer.
Some manufacturers make stiffer springs that you can put in your strut assemblies. I'm not sure about the Vibe, but cars that commonly are driven hard, like Mustangs, WRXs and such have a nice aftermarket for stiffer springs. Those manufacturers might offer something for your Vibe.
You might look at getting a small truck to pull your stuff around? My old Ranger can handle up to 1200-1500 pounds in the bed, and can pull 5,000 pounds on a hitch.
Have you looked into air adjustable shocks? You could probably find some that would fit, and then you could pump them up when you needed to level things up, air down for regular use. Between Vibes/Matrixes and Corollas, there should be some out there.
