Hi guys! First have to say how awesome my Slayer Pro is! I decided to buy a nitro r/c after messing with a co-workers RC10GT. Gotta love the smell of NITRO! Smells like the drag strip in my back yard now! But I have a few issues I was hoping I could get some help on. I'm a total newbie to the "hobby class" r/c cars. I have broken in the engine per Traxxas instructions and the truck is running great. My biggest issues are tuning the suspension. The rear end squats so bad under throttle that it has rubbed the paint off the body above the rear tires. I am going to get a sway bar kit after reading several threads. I guess what I'm asking is the shocks look threaded like coil overs on a car (I'm a gear head and build some hot rods), can they be adjusted to change the spring rate? Will this help raise the ride height a bit on the rear and keep it from squatting? The truck sits lower in the rear even at rest. Or do I need to change the rear springs to stiffer ones all together? Thanks for the help in advance guys!
