I run the same brakes up front on my Duster with 275/35/18’s and lowered maybe a smidge more than that. My front rims are 18x9 +35 which is about where you need to end up. 18x9.5” would work too, offset should be in the +27 to +35 ish range unless you want to start modifying things. For a Barracuda the additional concern would be the lower front corner of the fender, it’s more restrictive than Dusters or Darts. The height of the 275/35/18’s is ok but the added width will reduce the clearance on turning.
