Thank you for the advice! So far, I've added about 50 lbs with the current sound deadening material. To finish the car I'll need about another 18 lbs. I was hesitant to order the last bit, but I checked this forum again to re-read the information everyone has posted here. Looks like I'll be ordering it after all.

I should have a total of about 85 lbs including my audio equipment.

I hope that being my car is a VX, it doesn't struggle more from the lack of HP it has. I'm already getting roughly 30 MPG and I can't figure out why it's not better than that.

I'm beginning to have doubts... Some people are saying 80 lbs is a lot for a car that only has 95 HP. Can anyone shed some light on this?
