I have a 2013 Mazda 5 sport with 40k miles on it, and am planning to proactively replace the suspension at 50k miles. I'm thinking about going to coil overs, but have a question:
About 4x times per year, we load up the van for a 300 mile trip ( each way) to the in-laws. In doing so, we put about 500 pounds of cargo in it, on it, and out on a receiver mounted carrier. As you might guess, it squats low in the back, the front end gets light, and our headlights blind the oncoming drivers.
Would Coilovers allow me to dial out that rear end sag for those four trips per year? Or should I be looking at KYB shocks/struts and some sort of pneumatic helper spring arrangement?
coilovers will have a higher spring rate, which will not squat as much as the stock springs. also, you could set them slightly higher in the rear to accommodate the extra load.
