I'm running the 30* caster blocks. No it's not my first time running 2wd buggy, but it is in a while. I havent raced buggy seriously in about 8 yrs. and I only ran losi back then. I've been getting spoiled with steering and traction running nothing but touring car. I will certainly try the brown springs again in the front, but what about the rear? Do I stick with the silver or go back to the green? The car even at this point is leaps and bounds better than it was but I still feel like I'm missing something even if it's a small thing. I will check the slipper also. Thanks for all the help and keep it coming.
