If it were me (im a gen 2 owner) I’d say early gen 3. You relinquish all the phaser drama, i believe the sunroof is better , Coil sprung rear is the biggest reason tho. Thats a completely different ballgame/ advantage in my book. And if you want 37” tires thats the move 100%. Modding rigs is great but you really have to do your research and tweak to get the setup right. But when you starting off the factory with a tire that size you know everything is engineered around it already. All the calculations are done. So its a great starting point.
