Part T0274 came out a just a few weeks ago. It is the complete CVD setup for the rear of the MTX4. For the front of the MTX4 Mugen says to use part T0245. That is the same as the MTX3 front universal set. I use the MTX3 rear universal set on the front of my MTX4. That is part number T0249. I have never used Titanium for these parts. If you give them a try, let us know how they hold up. If it were me I would use the stock steel ones on the front and try the titanium on the rear first.
