I finally got my hands on a set of these superlight wheels. Will be replacing the CRX HF steelies with these. Since the Miatas are 14" I'll be buying new rubber as well. I have a lighweight set in mind that will also increase my diameter (over what the HF's are), so my REVs per mile will decrease. The entire package should weigh just about what the current HF 13" setup weighs. If it all works out it SHOULD increase my effective MPG. Yes, I realize that my speedo will be inaccurate. Well, I'll let you all know what the results are soon!!
