So i am looking for some wheel adapters so i can run some spare wheels that i have, only problem is the wheels are 5x114.3 (5x4.5) and stock are 5x4.75, i know its bad to run wheel spacers without hub centric, but is that the same case with wheel adapters? i cant find ANYWHERE that sells the spacers with hub centric. what are your thoughts on ADAPTERS!

If you have links to the hub centric adapters, let me know
 
I wouldn't use wheel adapters on my little red wagon.

They aren't all that bad if they are properly torqued. They are probably stronger than most cast AL wheels. I was watching Legendary motorcars the other night and they were vintage racing a C3 Trans Am Corvette in a Pro Am race at Indy with Little Al Unser being the pro. They set fast laps, bouncing it off the curbing and ended up finishing in the top 3 out of about 25 cars including real Cobras in what looked like about a 1 hour race that included a 5 minute pit stop for driver change/refueling... and they pull a front wheel off because brakes needed adjusting and damned if the car didn't have a 2" wide wheel adapter on it.

haha yea they are definitely safe, drifters use them all of the time one drifter has an r35 with 2 fat spacers stacked on for about 6" of extra poke
 
Measure the hub bore size of the wheels you trying to adapt and check ebay. I just bought a set of hubcentric 1.5" adapters for my Miata for $78 for 4.

If you get adapters that are hubcentric to the wheel, you can true them on your axles before you tighten them so there is no runout before you torque them down, then just bolt on the wheels with no worries.

Your studs are probably 1.25" tall so the adapter needs to be at least this wide, so the studs don't hit the back of the wheels.

Spacer are awful. I have had studs break and lost wheels from running a 1/8" shim spacer, but my 2+2 has run thousands of miles above 120 mph (up to 168mph) with 1.5" wheel adapters in back and I've never had an issue with them. I don't think I would use them with a high HP car launching with slicks, but the axles in a 7.5" rear will break with 300 less HP than would take to break wheel adapters.
