Bought my slayer in jan and wasn't really impressed of how it handled. A buddy and i went to a local track and ran for about 3 hours and i made just a couple of minor adjustments on the spring collars and it got better. I went and installed a sway bar kit and only have been able to run at work or in my backyard,and i can say that made a world of differance. Today i installed double black springs in the back with 50wt oil and swapped the rear springs up front with 45wt oil in the shocks. Then i installed a slayer center diff kit and the rear brake kit,and also swapped the stock wheels and tires with a sc8. All i can say is i can't wait for the rain to fially be over so i can get this thing back on the track. Just running it a work and in my backyard after these upgrades i can honestly say this thing is one of the best handleing rc vehicles i've ever owned.
