Meet the RP968: A 1500hp capable beast that shattered the Sydney Motorsport Park lap record with a blistering 1:17.860, dominating WTAC for four straight years in the EMtron Pro class.

It takes the full package to smash an outright lap record, and that's what the RP968 has done with teams of clever people like Ashley Field of 909 Motorsport behind the scenes and Barton Mawer behind the wheel. Despite running a large capacity 4-cylinder engine and a 1500hp+ capable Thor billet block from Elmer Racing, amongst other performance goodies, the Bosch Motorsport ABS system that is there to reduce speed, not increase it, has been a key player in getting the lap times as low as possible on the day.

With a switch from the M4 to the M5 unit and more fine-tuning of brake pad compounds and spring rates, the team has gone from seeing 2g under braking to 3g, giving everything on and in the car (especially the driver) a huge workout.

To reach this level of performance takes more than just slapping on a 'big brake kit' and calling it good, however, and Ashley discusses some of the considerations that go into a high downforce car when it comes to trying to have braking performance at both high and low speed without bouncing or loss of traction.
