We broke a trans cooler last weekend. It was mounted between the subframe connector and the drive shaft. Under the the drivers seat. Fortunately this kept all the fluid between the frame rails. But fluid was even dripping off the deck lid and tail lights. When cleaning the underside I washed the wheels and took a look at the recently installed 5/8 studs. The picture is the spokes of the rear wheel at the hub next to the stud washer. Every spoke on both wheels is similar. Ran this car for close to 800 passes. Converted to 5/8" studs this Winter. Never guessed the old 1/2" studs were stronger than the wheels. Doug

Good catch, another thing to verify is the wheel fully engages on the stud, I had to order a new stud kit after doing some mock-up and measuring, the screw in studs varied on the protrusion of the shank away from the axle plate so that a couple of the shanks did not fully extend through the wheel far enough leaving the possibility of the wheel wobble and or eventually egging out the wheel holes.

Good catch, Doug. On my 5/8 studs they are fully theeaded and use a sleeve for the wheel to ride on. Those sleeves backed out part way when i pulled my slicks to replace them. I mounted the tires, and put rhe wheels and tires back on not realising the lug nuts on the left rear were torqued tight against those sleeves! The wheel was actually loose on the studs. Luckily no breakage or damage after four passes.

In theory, there is no difference between theory and practice. In practice, there is.

just asking, is it normal to have that much weight to balance a tire ? Yes, sometimes it takes a lot of weight. Brian
