XRAY - Model racing cars

try minus 3 deg camber on the rear, u could also try the silver springs, the blue/grey are a bit hard and i dont see a lot of people running them here in the uk where the tracks are bumpy they tend to run grey or silver? i sometimes run the rear brace with no screw through the shock mount, i dont know if anyone has done this but it works really well and i find it has helped me on slippery tracks! i have had no troubles running this but i do run the metal rings beetween the pinion bearings? these are just a few things that have helped me and i know they wont be for everyone!

You could also try hole number 3 in rear roll center.

The biggest difference will probably be 3-4k in rear diff, but you will loose a little off power steering.
