Looks like I have to switch to longer wheel studs to pass tech in SCCA autocross. Anybody do this before and what's the easiest way to get the old ones off?

I'm actually looking for the same info.
I have seen people use a small sledge hammer to remove them.

What studs did you get?

How to replace 'em...

I have a box of 10 Land Cruiser studs, I want to eventually put em on the front so I can run a small spacer. My center caps won't clear the dust caps, if there ever was a worse reason to widen the front track lol.

I found taking them out was pretty easy, just use a hammer after spraying the base with PB Blaster. I only had to replace the rears since the fronts passed inspection. Here's some info I found:

I went with a box of 10 Dorman 610-312 for $18.60 shipped on Ebay. Thanks guys!

There's a nifty tool for installing the studs. Here's a pic:



Make sure the type of lug nut seat on the tool matches the lug nuts (tapered/acorn seat pictured above). In addition to the tool above you'll need a strong impact gun, and a lug nut or two (I recommend using old junk lug nuts, not your fancy lug nuts). Only use this method on used hubs or axles.*

*Use a shop press for the wheel studs if the hubs/axles are brand new - this is because the new hubs won't have splines cut into them yet.
