Hi, I'm new to the forum but even so I can't seem to find any good leads about how to lighten my car. I've got an 04 gtp with a little under 100,000 miles. I'm looking for a way to lighten the front end specifically due to the fact that I just got the car and in about 3 months my tires are bald and also I would like to get a bit better fuel economy. It's all stock except for new dis coils, plug wires, spark plugs, k&n filter (stock box). I'm also curious did they come with aluminium sub-frames, cause I'm pretty sure that's whats on it but I've never had that on anyother car. Does anyone also know the factory weights for things like the exhaust and tires. Just trying to think of things that I can replace with smaller lighter counterparts.
