When installing the Virgos (turbo rims) a couple of things to watch for:
Some of the wheel castings do not have a deep enough recess to clear the alignment pin/bolt that helps hold on the brake rotor. Get 4 extra bolts for your rotors before you start. They're a M6 thread X 12mm long. They have a 10mm head. It should be a readily available bolt at any hardware store. Extras can be grabbed for free at any junkyard. I'd expect to have to change these out to get the wheels to bolt up flat- and it's better to replace the bolts than to just leave them out.
Hopefully when you got the turbo rims, you got a set of the deep chrome lug nuts that go with them. They look correct as well as making life a lot easier for installing the wheels. The bolt holes are really deep on these wheels. It takes skinny fingers to get the regular nuts started down in those holes. A 3/4 inch (19mm) deep socket is very handy for tightening them. Anyone using a normal 3/4 short impact socket (like the tire shops use) will quickly find out that the hole is too small for their socket, and the socket will bind up on the aluminum of the wheel inside the hole. This can result in dangerously low torque applied to the wheel nuts! Loose alloy wheels will be chewed up and destroyed by this!! Another good reason to torque wheel nuts by hand and check your work!
Last, as with all old alloy wheels, there is the possibility for corrosion forming in the bead area where the tire meets the rim. Rim leaks can be tough to seal up properly. A little application of fine sandpaper or a polishing wheel works wonders here. Rim sealing compound can also solve this problem but it's really a band-aid fix.
Good luck and have fun! The car will look great with the new wheels on it.
