Dark Horse HP on regular DH. Will I need lowering springs? Or suffer from wheel gap?

I noticed the base Dark Horse rear tires - 275/40-19 comes with a tire diameter of 27.7 inches. The DH - HP comes in 315/30-19 - total diameter of 26.4
That is a difference of 1.3 inches. Im thinking about putting the DH HP (shorter diameter) setup on the base DH.

Question is, does the DH HP come lowered from the factory? The rear wheel gap on the DH HP doesn't look that bad TBH. Can I slap the DH HP wheel setup on a regular DH without some horrendous wheel gap? Or can I go up in sidewall - say 305/35-19?

The HP option is more than just big tires. It sits about an inch lower than stock DH, also the suspension is tuned differently wheel well flares and no spare tire different rear wing with gurney flap. So are you doing all these changes or are you just trying to put bigger tires on?

Just bigger tires. Deciding on how big and whats the limitation? Either Mach 1 HP or DH HP wheel setup without the huge wheel gap
