You’ll be way more than 4 grand with brakes , hubs ,shocks and springs maybe 6 grand would be closer, this is one of the reasons I build my own stuff ! I went thru the whole modified stock crossmember deal you still you still end up with the same old piece that has a lot of shortcomings
as far as structural strength etc. I can build a crossmember quicker than modifing the stock one
the biggest thing is the position of the rack hard to put it where it needs to be on the stock piece!
and we got this car to work with out a front sway bar!
