This is a Dick Miller set up that I took off my car when I put my 700hp motor in. This kit is recommended up to 550hp but you can buy upgraded upper control arms to take it to the next level. This kit already has the upgraded control arms for the anti roll bar and spherical/poly bushings. This set up cost over 700 and then I bought the arms for the 12 bolt too so two sets of arms are included. $500
Sean, your offer of 350 plus you paying shipping is fine, do you have an address in the states that these will be going to? Shipping over the boarder gets expensive
