I highly disagree. rear lower tie bars make a big difference
Our rear cross member is a thin/weak piece of crap. lower tie bars make a big difference. Look into the D3 designs kit its like 300 or so and includes tons of different bars that make a huge differnce.
IMO a decent front strut tower bar/rear lower tie bar, and for you eclipse guys the rear upper strut bar for the price is a great investment and works great
