i have to disagree i like airride and have had no problems with using it . coil overs are easy but they are hard to get both stance and ride in a low look .
yes, they make a kit for a straight axle ,
as far as a good school ,take your money move to a area that has a good rod shop and try to go to work as a grunt , and learn there , you will get a better education there than in wyotech !
