So, you all need to buy some traction devices. I had your basic aftermarket upper and lowers, and they sucked. Nothing compares to a set of Megabite Jr's or equivalent and they are only $200 which is just a few bucks more than regular control arms. Why do we all keep buying that crap. I dont know if you all remember me bitching about my crappy 60's and the fact I couldnt burn the tires even though I had slicks and control arms, well all that is gone now. With my street tires, I had to stand on the brake to keep the car from moving while I was trying to roast em. It was still moving forward though, but man was it cooking the meats. So today I went out for a cruise with the slicks on and crap is she fast, and no peeling out. This setup is awesome and still very streetable. I feel I have an insane rearend set up now. Mods are Auburn Pro, 31 spline axles, 3.55 gears, 5 lug disc brake, lakewood 50/50s, Megabite Jr's on max setting, adjustable uppers, and spherical bushings. So if anyone is looking for an optimal combo, that's pretty much it, but I'd use 4.10s if I was NA but I'm not. See ya!!
