Have these rims and I need to know what can I do to put these rims to my mazda rx7 1983. I want to know if i can and if i need something in special for it...Thank you in advance
those wheels came from a gsl-se. the lug pattern is 4x114.3. the 83 is 4x110. u will need to swap suspension from a gsl-se. considering they're the sane body, i would think it would be a direct bolt in. or redrill that pattern into your hubs and axles. or buy adapters.
What is your goal? If you are set on using those factory rims, one of suggestions is the way to go. If your goal is bigger wheels, you might think about buying something like a Konig 15x7 4x110mm 20mm offset. It would be the easiest path to new wheels and a better selection of tires.
The GSL-SE has a wider Hub to Hub distance, and these rims have a greater offset to give that car about the same footprint as a regular FB. Point being, if tou just drilled the hubs for a bigger bolt pattern the wheels would be in too far. might rub the springs, might look funny. An adapter could give you the extra spacing and be the easiest way, but I have never used them.
I saw it and I want to know if this adapter is correct for my Mazda rx7 1983 using those rims, what is the difference about the wheel side bolt pattern

Reason: Fixing
The non-GSL-SE cars have 4 x 110 bolt pattern.
The GSL-SE wheels pictured are 4 x 114.3 (4 x 4.5").
You need 4 x 114.3 on the wheel side. And about 20 to 23mm thick spacer. That 1" / 25mm thickness should be fine. But again, I've never used spacers, so maybe someone with experience can comment. I am replacing the suspension and brakes to convert to SE specs, and it's not cheap or easy to find parts.
If you need a budget option for larger wheels, The 15x7 steel wheels from a Chevy cobalt have the right offset to use with a hub adapter to 4x100. Hub adapters push the hub face outward, and the cobalt wheel has an offset that is larger than the stock offset by the same amount my hub adapters were. Also, my hub adapters were $65 a piece and the wheels, new, were $40 a piece. Black wheels don't look half bad on an FB.
Of course if you have the GSL-SE wheels, those are beautiful. But you're going to need to replace your front brake, hub, and wheel bearing, and your rear axle with GSL-SE parts.
Spacers work great. I am using them on my endurance racing car. The minimum thickness though is about 1", to give room for the two sets of nuts. Try adaptitusa.com. They made the ones I have been using. My only recommendation is to make sure that you use all 4 nuts to hold the adapter to the hub! ;-) I somehow forgot to install one nut of the 4 and lost the wheel and adapter in T3 at Willow Springs a year ago after about 1000 miles of racing. That was a pretty big oops. Otherwise many thousands of miles with no problems. Actually heading back to Willow Springs tomorrow morning for another 14 hours of racing.
Of course if you have the GSL-SE wheels, those are beautiful. But you're going to need to replace your front brake, hub, and wheel bearing, and your rear axle with GSL-SE parts.
If he can find 4x110 to 4x114.3 adapters, 1" thick, he wont have to change anything else.
4 x 110 is what your car has now.
4 x 114.3 is the bolt pattern on the SE wheels you are trying to install.
My Mazda rx7 1983 and I'm trying to put a rim of Mazda rx7 85 ... And I haven't to much $$$$ to buy all the system of Mazda rx7 85.ai don't know if u r understand me or I understand u all
mayopr, listen to us -
Your 1983 rx7 has 4x110 bolt pattern. The wheels you showed us are 4x114.3 bolt pattern and a different offset. You need Adapters-
4x110 on hub side, and 4x114.3 on wheel side. They should be about 1" (25mm) thick.
The 4x108 adapters you keep showing us will not fit the new wheels.
