I am not sure about the power to weight ratio but it would make sense though considering the extra length. Handling wise, so far so good with mine, good and tight around corners and bends, some how looking tidier...but that might be due to the sway bars I have on mine.
On the 36, I don't think the difference is that big with sedan and coupes. Both are well built IMO...and I would upgrade the sway bar over the struts. The 36 chassis is quite solid and does not flex as much. Best mod I've spent on the car so far is the sway bar PJ could tell you that as well haha
