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.
