At 29" tall that's too tall for an MN12, factory tire height was 26.5, give or take 1/4". You'll be losing at least 10% of your drive torque due to the gearing effect of the larger tires (e.g. the same feeling of going to a 3.08 if you had a 3.55). Your speedo will also be about 10% too slow.
Plus I don’t know if the intent is to just run them on the rears, but that’s the only place they will fit, front doesn’t have enough clearance for the upper ball joint above 27”. People have run 29” slicks but there is some reports of rubbing at the front of the rocker, the hubs aren’t fully centered in the wheel opening on these cars.
