I was on the highway this week for a few miles and I hit a patch of bumps that launched my rear wheels off the ground. The impact when the wheels hit the ground caused my head to smack against the headreast. This happened numerous times. I had a bad headache in no time. Perhaps a minor concussion.
Anyway, since I hadn't been on the highway much since the "drop" I didn't realize how bad the ride could be. I'm thinking about undoing the coilovers and going back to the stock setup. If so, I should be able to quantify any difference.
Loss meaning the gassy mileagey thingy. You can prolly get your money back selling the struts, (that's what I often end up doing).
Somehow I don't think the gas mileage will change that much. I think that the increase I saw had more to do with warmer weather and better technique. We will find out for sure if I change back. I wull keep the struts however, except for the one rear one that had the missing flange. I don't know if that one will work with my stock springs.
After about a week, I have noticed no measureable drop in FE by going back to the OEM springs. So much for the gain I thought I had. Probably just improving driving technique. Anyway, i just found this DIY on lowering a Prius. Seems like lots more work that i had to do with the Del Sol.
