Would any one be interested in a wheel spacer to allow +38 to +40 wheel fitment with their RE Speed TII front brake kit? Hub cententric to hub and wheel. They weigh 1 pound each and require the use of ARP 100-7713 studs or equivalent. Price would depend on the number of people interested. Could be $200 a pair + shipping.

I'm interested in 1.25" spacers so I can use my FC convertible wheels on the REspeed kit. glad to see they would be hub centric to both the wheel and hub, most aren't..

13BT_RX3

What is the back spacing on the FC convertible wheels?

13BT_RX3

The reason I asked is because 1.25" will be too big in my opinion. The specs I have for the Convertible wheels is 6" wide with +38 offset.

A 20mm spacers worked perfectly for me with my 16x7 +38 offset wheels. If you are interested let me know. If not you won't hurt my feelings.

will those spacers come with new longer studs? from the looks of it, it looks like it will just go over the hub and that will cover up all of the hub studs.

13BT_RX3

Yes, it won't work unless you purchase and install longer ARP 100-7713 studs or equivalent. Longer studs are a safer choice than aditional studs mounted in the spacer.

I think the convertible wheel is 6.5" wide.
go to this thread: https://www.rx7club.com/showthread.p...0&page=2&pp=15
and look at post number 18, by stilletoman, he has the vert wheels on his and says it needs a 1.25" spacer to work correctly. Unfortunatly I don't have the respeed kit yet, so I can't actually test fit my vert wheels to be sure...

Running as slim a spacer as possible will reduce the chance of rubbing on the inner fender lip wider tires. I suggest that you do more research to be confident that the wheel tire combo you choose is compatible before you buy any spacers. The specs I have from Tirerack for installing 15x7 and 16x7 wheels on a non-GSL-SE requires +18mm offset. If you add a 20mm spacer that puts you at +38 for the same size wheels. If you choose a narrower wheel with the same offset it should yield more clearance since the tire will be centered in the same position, but won't be as wide. The picture I posted showed a 16x7 +38 offset with 205/45s. There is plenty of clearance even with coilovers.

Accroding to all the threads in the second gen section the vert wheels, along with all the FC wheels have 40mm offset. I'm fairly certain a 1.25" spacer will be required to run those wheels, stilletomen in that thead I posted the link to used a 1.25" spacer, as did Directfreak when he ran vert wheels (I forget which thread I read that in)

13BT_RX3

If you are more comfortable using 1.25" spacers then use them. They will give you 16.1mm more clearnace at the strut than I have shown in the pic above. Not sure how this will affect fender rubbing.

Woluld anyone prefer 22mm spacers?

After doing some quick calculations (literally on the back of a napkin at lunch) it would seem, at least on paper that 1.25 is too big as you say. I'm wondering is that 22mm spacer would be fine after all... Anyone else care to chime in on this?

I posted in another thread that a 1" spacer with a +38mm offset wheel is just about perfect, but it seems as usual nobody read my post. I even made my own thread about it to end all the questions about the topic, but again, it was ignored. I spent almost an hour going through the measurments with the stock wheel and an aftermarket 16x7 I have here, using a 205 tire as a base for measurments. 1" spacer is about as perfect as you can get.

Oh don't get all emotional about it I read your post earlier, just after my last post in this thread, was going to link to it here and comment on it, but ran out of time. I have a few minutes right now so I will do that now.
Here's the thread he's reffering to, and your measurements confirm the calculations I was doing earlier. https://www.rx7club.com/1st-generation-specific-1979-1985-18/end-all-wheel-fitment-respeed-brake-kit-588603/
Unless you and I are both missing something a 1" spacer should allow fitment of any of the FC wheels since they all share the +40mm offset.
The one question that still remains is whether the 22mm spacer he is advertising in this thread will work in all cases. It does on his car, but he has coilovers. I wouldn't think that would change the dimensions much, but 22mm is approx .87 inches, would that .13" really make much difference? I'm not sure. Guess I'll have to get my respeed kit and see for myself.
I will say one thing, finding 1" spacers for 5x114.3mm pattern that simply use longer studs (rather than new studs on the spacer) seems to be hard to find, unless I'm looking in the wrong places.

22mm would probably work fine. Seems there is enough room there. 0.13 of an inch is not very much at all. If you had a tire with very little sidewall to flex in, you could decrease the amount of inner clearance to probably 1/4" instead of the 1/2" I allowed for.

BTW, I'm not getting emotional. You don't wanna see emotional I just wanted to see the reaction I would get.

I originally suggested the thinner 20mm spacer like I'm using to avoid fender issues and minimize scrub radius. If you have spring contact issues using this spacer you could always add a small universal spacer.
Like => http://www.stockcarproducts.com/wheels2.htm

If you were to opt for wider spacers initially and had fender issues you couldn't fix that with spacer tuning.

If you were to choose a 22mm spacer and later decide you needed more room you could install an 1/8" spacer, putting you near 25mm. You could place the tuning spacers either above or below the main spacer since it is double hub centric. The length of the ARP studs won't be an issue since they are a little more than a 1 inch longer than stock FC studs.

Also, if people wanted a dual bolt pattern (4 and 5 on 114.3) that could be done too. I would just need to play with the weight relief pockets to ensure neutral ballance.

The question is can we get ten or more people to agree on the same design.

I'm interested in a 22mm spacer for 5x114.3, no need for dual bolt pattern for me. Are you making these or having them made?

85rotarypower

I'd be in for these if I didn't already have a nice set of wheels in a different bolt pattern. I'm getting adapters from Adapt-it-USA, 5x114.3 to 5x108. I'd love a 22mm thick adapter, but thats too thin for a full bolt pattern adapter. I'm stuck with 1" or more.

Here's the link to our subforum where they are selling hubcentirc wheel spacers that don't look too bad.

I'm sure the spring makes a difference as well.your springs look quite narrow compared to my 1" lowering RB springs. the red ones
