I haven't heard of this mod but just FWIW, I race OffRoad now and use the 4PL as do about 50% of the racers at my local track and with people slamming the wheel back and forth from stop to stop way more than any OnRoad racer ever will (or should) have never seen a failure of any part on the TX. I would not let this "issue" prevent you from buying a 4PL.
