anyone running AMR Mustang Wheel?

Hello,

I've spent the last few days reading all the threads about the mustang wheels and larger wheels and have found most of them talking abou a-bodies with larger wheel openings than my 74 swinger. I have been searching for a rim and i found these AMR Mustang wheels.

My car has a Tubular Front suspension from Badart
Factory front Disc
Stock length a-body 8-3/4 with Dr Diff rear disc conversion.
1/2" spring relocation kit

For the Front i am looking at the 18*8 with 5.68" BS and 30mm offset and a 245/40 Tire

For the Rear i am looking at the 18*9 (would like the 10 dont think it will fit) With 6.18' BS and 30mm offset and a 255/40 tire

Would this combination work? i would like a wide tire but would prefer to play it safe with the first setup. any opinions?

Thanks
