it doesnt mean it is lighter.. it means it is heavier i think.
its the max load u can put on that axle right?
well if he can put less weight on it it means his car is heavier mate
update i just looked up the weight of the 2.2 coupe wich is 1198kg while the 2.0 turbo coupe is 1245kg ...
also the max weight a 2.2 can load is 467 kg vs 395 for the turbo
