Possibly (the higher drag thing). I don't really have anywhere to coastdown test (not going to do it on a public road), so this is unfortunately the best I can do. I can't run through full tanks to get meaningful results because I do so little driving and my engine is cold half the time.

I think the Spyder rode a little over 6" off the ground stock, I've now reduced that to roughly 5". Stock, the wheel well gap was simply massive, now it looks like a stock BMW. I believe raking the car forward should help the aero over the top of the car since the rear end is not high enough to meet the template, and the underbody aero is garbage. The rear tires are 205s which is a bit wider than most econoboxes, so the reduction in air going to the tires might have a decent positive effect.

I think it coasts a little better now but it's hard to say. Now that I have new shocks the ride quality is a little better despite the stiffer springs, so I might try to pump the tires up a little more to see if I can get more coasting distance. Currently they're at 36/40psi front/rear (on the door it says 28/32 or something) since the ride was kind of harsh for my taste.

Handling wise I think there's a bit of improvement. Less body roll because of the stiffer springs, and less brake dive. I have very little negative camber and Macpherson struts so the camber loss might have been a problem. I took a very sharp turn today at 30mph that used to make the car slide a tiny bit, zero drama this time.
