since fitting the RCs I have really noticed the fuel economy dropping- was happily doing 52 on my run to work, now doing 48. Not a lot but noticable. Has anyone had anything similar? And what did you do about it?? Wheels still need aligning properly- its pulling to one side, but that shouldn't make any difference, and pressures are at 34psi so that won't be it. Any ideas? The wheels are only 2kg more per wheel that monty2s, so not sure whats happening.
