89 EF 4wd sedan
Sorry to hear about your debacle. Dealing with shit products is one thing, dealing with a company with bad product support is another thing all together.EFB055, springs is not only sagged . Yesterday I talked with the other person with 2nd RM set. They measured the spring rate of some springs. There was a differences of 3 kg/mm2 ...... His car is not more than a 20-30 miles.
You are a technical person, and probably You know even if spring is sagged , the rate must be the same. The different rate can only be due to poor quality material.
