I bought 1.25" wheel adapters from ebay not knowing the bore size of my FC and the adapters I have are 67.1 mm so the stock wheels didn't fit over them sadly. Anyone know where to get a 1.25" 5x114.3 (5x4.5) hubcentric wheel adapter spacer with a 59.6 center bore?

 

Ebay. Just get the set intended for the FC. Both hub bore sizes are on there... just make sure the listing says it will fit an FC (59.5mm bore) and not an FD (67.1mm bore)

Alright thanks.

 

Now what if you have wheels with a bigger then 59.6 CB do they sell adapters to fill the space so all the weight of my car is not resting on my studs?

 

Yes there are many sites that sell adapters to fill the space so its a flush fit onto the stock hub. Im getting these aluminum hubcentric rings for the wheels Im eventually going to get. Aluminum rings are much better to use than plastic or polycarbonate rings since they could melt on, or crack and break off.

spacers usually made to stock bore, if you need rings those are a different product.

Rings are cheap last set I got right from BBS think they were under $20 shipped

 

or you can get a set custom made here:

Yes there are adapters. I got mine off ebay. But the wheels are always supported by the studs and not the tiny lip of the centering ring. The lugnut seats in the wheels are conical and match the lugnuts, so they end locating everything.

 

H&R spacers for a 626 have the right specs. I actually have a pair of their 25mm spacers if you're interested.

I may be interested in those spacers, but yeah i found out my wheels are lug centric and dont need rings, so ive figured that out at least...

Now for studs, my current wheels have the lugs holding on by a *unt hair, because i had to run an autozone 5/16 spacer to clear my 4 pistons because of that nub on the caliper,

Ive pondered grinding that nub off so i dont have to run spacers, is that safe and can it be done.

also what if i ran 5/16 spacers on all 4 corners,

what size stud length do you guys recommend i know the rears are smaller?

if someone can give me a company and proper length for extended studs ill need to clear a 5/16 spacer on all four wheels id be greatly happy and thankful.

Thanks guys!!!

 

drift- your autozone spacers are not hubcentric- which is a problem.

even if you have lug centric wheels your SPACER needs to be hubcentric for that car especially using universal style spacers. I threw a set on to figure out what size I would need and the car had a pretty good vibration @65mph

 

I have no vibrations tho there steelies deff lug centric, there just a temp thing because i haven't figured out if i'm keeping stock fenders, wide ones or 240z flares, but will probably just pull my fenders, hence why i haven't got new wheels yet, thing that sucks tho is i started a new job and this car will be a daily for a while.

I at least need to get extended lugs for now, thats what i really need help with.

Also what about the question about the nub above on the calipers?

Without that nub i should be able to run no spacers i think.

Cragar v-5's if that helps

Budget build and money sucker of all my funds till the money from my new job starts rolling in sorry for my redneck truckerness

 

Kenshin sorry for the thread take over didnt see a reason to start a new one to further clog things in the second gen section and threw searching it brought me here and with Nismonic weighting in (were kinda like friends although we never met in person) i knew i came to the right spot to ask. And even further Rob XX 7 is super helpful. Thanks a million guys!!!

 

I think its about time i make a build thread so you guys can weigh in, i'll deff need a little help and am super open to advice and recommendations.

I know N/A rx7s like the back of my hand but am so new to turbo cars.

 

The "nub" is a fluid channel between the pistons.
I had to grind my calipers to fit wheels, but only a little bit.
I've been curious ever since how dicey that move was, how close to breaking through did I come?

I have a trashed caliper around here somewhere, I should grind one down and see what the clearance actually is.

 

Okay after further inspection even without that nub i'll still need spacers and because of money restraints i have to rock the steelies for now and can not get baller wheels yet, i dont even have a set of stock wheels to just go back.

I need the right spacers and lugs spacers will be easy for me to look up and find.

But i wanna get the studs right the first time and am not confident on me getting the right ones.

Ill get 2 8mm spacers with a 59.6mm bore thats easy.

I'm gonna need your guys recommendations with studs without going to excessively long?

Only to be pulled back out one day when i buy my friends Work Ewing III's and A new set of spacers to get the stance right when i figure out what look i'm going with body wise.

Which will probably just be pan speed fronts and pulled rear quarters.

 

Rears look nice tho lol 15x8 3.5in's backspacing (-17 offset im guessing) NO spacer needed life...

 

The Works brand new, tires never mounted, 5x112 tho, just dirty.

But at the price ill get um for and with the center caps these babys are gunna get drilled.

 

Check this thread for stud dimensions.

You might also be able to get away with using "Extended Thread (ET) lug nuts". Never used them before, but they should solve the problem you're having.

 

Do you mean Mag style lugs for Mag wheels NO NO cant do that on the skinny steelies.

 

O wow never mind i just yahoo image search those idk if they would fit tho my studs are snug already in the lug holes on the wheel.

 

3 1/4 sounds like the way to go, so i can work with spacer sizes.

Is j-auto good site?

Is there an Oem equivalent to 3 1/4 from some random car?

 

I guess ill just get ARP's thats the best way.
