Re: UPDATED '85 Cutlass build "First Car" (Lots of pics!)*
hey Mike, good steal! Can't find these rims up here for less than $400... and usually in rough condition.
If you're car's gonna be silver, I'd go for a "Charcoal Gray" colour like this
Black would look good too, but it's been overdone with GNs... so your call
All four are 16x8.
the fronts have 4.75" backspacing
the rears have 5.25" backspacing
You can mount them in reverse, or mount them as directed, but in either case you will need a 1" adaptor for the "Back" wheel with 5.25" BS. Using a 1" adaptor will bring the BS down to 4.25" which is a far comfier fit for our cars.
I mounted the "Back" wheel on the front of my car using a 1" adaptor, but mostly because I didn't want to put alot power down on a adaptor. I don't do alot of hard cornering, so the adaptors work fine upfront.
In the rear, I did have to use a 3/8" spacer. Alot people have gotten away with a smaller one, like 1/4" or even 1/8"... it'll depend on your car.
My next problem was studs... the wheels have a thick casting, so with a spacer, my stock studs wouldn't reach far enough to grab enough threads. So I got some extended studs, 2-7/8" long... ARP or Moroso carry a wide variety.
But these long studs caused another problem... they were TOO long, so the normal "acorn" style lugnuts didn't seat. So I bought open ended ones.
Make sure you buy ones that are tall and have a proper conical seat. Small lug nuts will sit too deep, and you won't be able get a socket onto it.
... And I think it's worth mentioning, I had so many problems with studs because I kept the stock 7/16-20 thread size, which is not carried by alot of parts stores anymore. You'll be able to find more variety in a newer metric thread, and you may not need the full-on 3" extended type.
check out ARP for studs, and Gorilla for a variety of lugnuts.
