I believe an electronic arm pops out of the dash and slaps accross face.

But other than that, you'll be fine.

I know where you can get one made... I thought about it, but I'm going to let someone else be the guinea pig on that one (for now)... eventually I'll probably do it.

The OEM 17s weigh in the 24-25lb range and the coupe 19s are very close to that (within a pound). I'm not surprised your aftermarket 19s are lighter (probably close to 20lbs), but the tires make up the loss when compared to the 17" OEM setup.

Then there's two other major factors at play:

1) With larger rims, the mass of wheel/tire is further from the hub which makes it harder to accelerate.

2) Wider rims/tires and sticky tires greatly increase drag and wind resistance. A 245/40/19 is over 1.5" wider in profile. That's a big increase in drag.

My aftermarket 18" combo weighs 1lb less overall than my OEM 17s. The width of the 18" combo is 1.2" wider than the 17s. Overall, when I swap rims, my MPGs drop a solid 1-2mpg. That means the car is using my fuel/power to overcome the drag.

Wrong the coupe 19s are not within a lb of the OEM 17s. Theyre like 4 lbs lighter. The oem 17"s are 24-25lbs, the coupe 19's are 20lbs FR 21lbs rear
