What to do...

Almost none... Got rid of the heavy bumper brace in the front, aftermarket seats and no rear seat, qa1 controls arms, caltrac rear suspension (I would think that stuff is negligible but there seems to be a small weight difference. Looks wise I'm just going for weekend warrior type look, but I'd rather have function. I'm going off the stock weight...3150ish+frame connectors75+me 330lbs...
Honestly if I can get it into the lower 11s NA up at my home track, it would be extremely competitive for basic shootouts or grudge night stuff. Once I get it sorted na I might add a 100-150shot, but not until I have more safety equipment.
Yeah I like what 12 many was saying. Get it weighed so you know where you stand. I've went to like the scrap yard or just one of the highway truck scales. I like to weigh the front and the back and see how balanced the car is as well. I know on the 73 there's a lot of weight in those bumpers and also they have the girders inside the doors that can come out...
