I modded mine to 2x1.8mm (front) and 3x1.7mm (rear) and loaded them up with 35/30wt CML/Fastrax oil after Craig's (Hulk) advice.
Instantly I had doubts as the car felt so light and bouncy compared to my previous setup of 6x1.2mm (f) and 6x1.3mm (r). Last night ran them at Ludlow (very bumpy grass) and the car was transformed! It just ate the bumps for breakfast. The smaller bumps I didn't even notice and the larger ones that were throwing a lot of cars up into crashes it lifted, but once back on the ground carried on without a sniff of being unstable.
My Dad's SX on big bores looked very lively compared to mine!
Just need to test it over jumps, but I'm feeling very confident going into Kiddy on Sunday
