Seems like certain upgrades can have a bad influence on fuel economy
... after finally gettting some of the suspension parts in (front & rear sway bar, pan hard) and Tony putting them in, flew home ... not sure how many MPG I got, but I ran it at or close to the speed limiter for quite some time; hit the limiter several times (that's the next thing Tony has to get rid of for me ...). With the sorry excuse GM put on the car (they could have put a string in the back, would probably have been better ...), I could hardly keep the car going straight at 90+mph when going over bumps ... forget about the corners ... it's no BMW suspension yet, but a LOT better ... stays straight, and turns great ... even stays controllable power sliding ...
Roy, watch out, I'm coming for you at the next AutoX ...
(well, not the next one, but after that ...)
