So, as stated correctly, the MPS3 "IS" heavier, thanks for proving my point, cheers.
I didn't say by how much, but Mohawk is right 20+kgs is is more than enough to be felt. Especially when most of it is in engine and suspension weight over or infront of the front wheels like in the MPS3.
I "DID" however, specify that the extra weight, while through implication only, that the setup made it feel dull, lifeless and heavy. I didn't go into specific's but the MPS3 after a full day of driving more than 200km's felt overly front heavy with little steering feedback and had a tendancy to understeer badly and roll when pushed through the twisty bits (Old Pacific Hwy - Sydney to Central Coast & back - My favourite road).
IMHO, the spring/shock rates could be changed, I didn't like the way the LSD locked up mid corner when the power was re-applied, the car felt undertyred with only 215/45/18 tyres (VXR @ 235/35/19 / XR5 @ 225/40/18 IIRC), the centre of gravity is to high (MPS3 @ 1465mm high vs VXR @ 1420mm / XR5 @ 1447mm) causing the car to pitch and roll more than others. But it has a goo interior and is quick in a straight line...Kind of like a Soccer mum's drag car....I don't think any of them could really be called a "Drivers" car, but the MPS3 is the least tuned to being a sports car of all of the current Hot hatches.
Mohawk: glad to give ay a laugh....I'm here all week...
