It's about 70-75 lbs heavier than stock.
For a power adder car it can really make sense due to the increase in reliability. Better clamping force with iron to aluminum... Less distortion of the deck surface due to heat etc...
The increase in weight is nothing to scoff at.
just remeber to drill and tap the missing holes and use shimms for the ones you can't drill.
