I have a 23mm front bar with coilovers 340lb front, 4way adjustable shocks, 3.2 degrees neg camber, 1.5degrees castor(standard rods), toe 0.4mm. Rears fixed as original with 220lb, koni reds and standard 18mm bar, 1.9mm toe. Seems to be very neutral in handling, with easy turn in. I ran with the rear bar connected and disconnected at phillip island and it didn't make any noticable change to driving feel, times were the same too!
Its still driven on the road but the front is very stiff on the smallest bumps
