You should not be breaking studs on a car with the HP level that you have. I have never broken a stud on my super stock car even when I was running 1/2 inch studs. Check to see that the back of your wheels are flat and make full contact with the axle face. If the wheels are concave or hollow on the back then you will have problems with the studs. What size studs are you using? I always torqued my 1/2 inch studs to 75 ft lbs. You might be over torqueing yours. I had Moroso studs in my axles.
