1. The front appears "higher" because of the requirement for the front wheels to turn left/right.
2. On some models the rear can sag a bit.
The springs are not interchangeable end to end. The fitment and rates are different.I would like to get the two ends even, would it be possible to get some rear springs from a junk yard and switch them out with my fronts?
Find out which case above you are seeing. If you want to "close" the front gap the conventional way of doing this is to get lowering springs for all four corners. This is because the springs typically account for your goal -- a common one -- and by getting a set the rates will be sensible and safe, keeping the car balanced. On a bugeye, also change the struts (dampes) since time isn't kind and the springs will be lower plus stiffer anyway.Or any other suggestions?
If you have sagging rear there are fixes available, spacers you can buy.
Find out the problem, set a budget, and contact the site vendors to see what prices they can offer. IDing the problem is first though.(Cheaper the better, without cutting my original springs)
