control arms

i heard there is a company making control arms that are 3 inches longer than stock, and if you use them with a non dually front rotor it pulls the wheel in 3 inches

except for looks, why change arms? i pie cut mine, and the front lays on the ground with a big @ss stock tire, about 3/4 taller than a 24..

The semi wheels with adapters are too wide to tuck on my bodied squarebody
