I bought an 87 ES to replace My 87 E,I replaced the front shocks on my ES with koni adj,The ES does not ride as smoothly as the E and there are a number of small vibrations and rattles The car has 100,000 original miles and rides on orig 14" baskets.I am thinking about replacing the ES springs with E springs to solve this problem .Has anyone with experience with both cars noticed this ...?
