I have a pair of what I believe to be American Racing "Vector" look alikes that are 8.5" wide for the rear of my TR with 275-50 Nittos. I got them (used) with slotted lug holes (dissappointed, but never thought to ask the guy I bought thru the T-Rader) Anyway, I am trying to figure a safe way to mount them...which lugs to use? Can I get special adaptors to fill the slots or have them filled? Just bolt them on and don't worry about it? They will see the track maybe 3-5 times per summer. Advice appreciated. Also where can I get the Am Racing caps for these wheels? How much?
