Heya, I was just wondering if the rear suspension was the same across the base hatchback and/or sedan? I'm not sure if they all share the same trailing arms and what not. I'm aware the speed3's thicker sway bar but unsure of what else. Just as a general question inquiring about if their rear...

Heyo, just wanted to probe someone else who might be more knowledgeable than I would be. I recently spoke with someone who had a merc and got to take a look under the engine bay when he mentioned that those motors use an auxiliary coolant pump that will continue to pump coolant while the car is...
