The goal with the big rear bar is to transfer the energy from the loaded outside rear tire to the unloaded inside front, attempting to keep it planted and hopefully giving it more grip both laterally and for forward acceleration. Small gains in mechanical grip can provide substantial gains in lap times). The disclaimer here (before I get totally ripped on the GRM forums) is that there are many ways to skin a cat when it comes to car setupfar more than I have space here to go into.
