I did the 06 mono to 136" in my RX-1 without any problems. I did remove all the tunnel and heat exchanger rails since I put a 2" challenger track in for out west too! I didn't have to change out the stock drivers just gear down to 23 top and removed all clutch weights from my supertips and it worked like a charm. Normally I run a 1.5" ripsaw and did have to remove the tunnel protectors since they rubbed the track, but not the front heat exchanger ones they had to come off with the 2" track. Hope this helps.
