Looking to verify an accurate size for hub centric rings for an '83 running 15" Konig Rewinds. Thank you guys!

I got these lugs and hub centric rings for my Silver KONIG REWINDS last year from Summit.

Do these bolts happen to be longer than stock? I have not measured the stock ones yet and was just curious.

Shorter I think. I'll have to check.

Just caught your thread. I have an 84 GSL and just purchased the Konig Rewinds in 15". Also ordered the Gorilla wheel lugs where every lug nut is a wheel lock. Part# 47179NBC-20.The are longer than stock but work fine. Wanted to ask what tire you selected and what strut/spring combination your using. I'm having a tire size fitment problem.I've got Tokico struts and Eibac springs which lowered the suspension about 1". My new 205/55R15 tires are rubbing on the front springs. Backs are fine.

Do you know the offset of your wheels? Likely 15"x 7" width
Most run 205/50/15 tires,the 55 series tire will have a "wider " sidewall. How much contact do you have? May be able to put a spacer between wheel & hub to move wheel slightly outwards.

Just use a spacer. It won't need to be very thick, but you should measure to get the right thickness. I have used 1/4", but I think 1/8" might have been enough. That has worked fine for an endurance race car, so definitely should have no problem with a street car.

Contact is considerable. I have a +20mm offset with a 4.79 backspace. Tried spacers and found myself up to 1/2" which was starting to push the tire outside of the wheel well. The rims are 15 x 7. I'm going to find a local tire guy to let me try a 205 50R15 on the rim for fitment. If that works, I'll have a brand new set of Kuhmo's never on the road for sale. Thanks for the feedback guys. Stu

That is interesting. Maybe the tire is the bigger problem. We have used a variety of 205-50-15 tires with only the 1/4" spacers.

I have 205/50x15 on mine and I have cut my RB springs by one coil all around. On hard cornering I had to slightly roll the lips of the front fenders but no spring issues.

I do not have the wheels handy to check the offset (ET), but maybe that is where part of the problem is. Were all 15x7 rewinds in 4x110 ET20? Or is it possible there were different options?

Something seems a little fishy about the reported offset of 20mm and 4.79" backspacing. My calculation for 20mm offset is 4.3" backspacing. Of course, my calculation might be wrong. 7" wide rim is 177.8mm, which gives 88.9mm on either side of centerline. Adding 20mm offset gives 68.9mm on one side and 108.9mm on the other. 108.9mm = 4.29"

The reported 4.79" backspace is easier to measure, so probably correct. That probably makes sense with needing such a thick spacer to clear the spring.

Just a thought. YMMV.

I have 205/60/15 on the front. They rub only at close-to-full turn. My front suspension is stock springs with tokico struts and a RB sway bar. I need to get a smaller tire yet, but it sounds like you are having a bigger interference problem than me.

I would recommend 205/50 if it is only a slight rub. 205/55=112.75mm wide (sidewall to sidewall) and 205/50=102.5mm which is a difference of ONE CENTIMETER between the two in TIRE HEIGHT. Sounds like a small amount...but apparently plenty to make a difference. Of course this wouldn't help if the tire is simply too wide, but it may be possible that it is too tall. Thoughts?

Oh, and I searched for hub centric rings made of aluminum such that they would actually last. Found a nice set which are the same size (73/60 i believe) as the recommended set. They fit excellently!

Hey Guy's. Back with a tire fitment followup. At your suggestions and the recommendations of the guys at Tire Rack, I purchased the 205/50R15 Yoko's S Drive to mount on my Konig Rewinds. Was looking for a home run here but was instead disappointed to find the tire still rubbing on the front springs as soon as I lowered the car. (1984 RX7 GSL). Would require more than a 1/4" spacer to cure this. Next thought is to go back to the stock springs which I no longer possess. Been trying to track down a set, but most places are pushing the sport springs I already have on the car. Thinner tires is not the solution I cared to consider.Open to more suggestions. Thanks, Stu

There appears to be something wrong here. I have used those wheels with both Spec7 lowering springs (basically the stock shape but a little shorter and stiffer) and 2.5" coilovers. They both needed about 1/4" spacer, but were otherwise OK. The backspacing measurement you gave earlier and the et20 that you reported do not seem to match. I suggest remeasuring the wheels and make sure that the cast in (as I remember) et20 matches your measured backspacing. I think my calculation (although I have not gone back to check it) says that ET20 on a 7" wide wheel should be 4.3". You were reporting something significantly different that would result in the tires rubbing. It is possible that the wheels are just labeled wrong and are more offset than they are supposed to be. That seems weird, but weird stuff does happen sometimes.

I agree. Konig 15x7 +20mm off set is a common wheel install along with 205/50/15 tires that many run with stock height springs with no problem. A lot have them on lowered cars(RB springs) with no to minimal contact,ones with minimal contact due to trimming/cutting a coil or more from front spring -this contact being at fender lip and almost all cured by fender rolling. Op is mentioning heavy contact on spring when car sitting on ground. The nature of the suspension being that clearance dimension does not change with car in the air with suspension hanging or weight of car compressing springs while on the ground. So the tire therefore must be contacting spring while car is off ground also,simple spin of tire would reveal this.
Only so many variables can account for this.. incorrect wheel offset being one. Have seen these wheels advertised in the aforementioned +20 mm offset for 4x110mm pcd which is perfect for all 1st gens(exceptSE) have also seen them advertised at +12 mm 4x110pcd and others at +0 offset though these are in 4x114.3mm offset.
If it is indeed proven op has +20mm offset wheels,next possibility is previous owner switching suspension components to those from an SE which had as factory +40 mm offset 4x114.3mm wheels in which that +20mm wheel/tire would be hanging out of fender and op complaining of fender/tire contact-which is the opposite of his complaint,so this is not a likely scenario.
Another possibility,albeit a stretch is spindle/strut tube(s) bent,either thru accident or purposely done to increase negative camber which if severe enough could cause tire to contact spring(and seen& felt spinning tire while still in air). This could be determined thru analysis of alignment readings.
Most likely scenario is incorrect wheel offset. Op could post actual#s (include receipt for wheels or part# that can verify offset),actual backspacing & lug bolt pattern. It uses bolts not studs/nuts,correct?

Thanks for all the assistance guy's. Talked with the guy's at Racing Beat today to get info on their springs recommended for this car. They're showing the spring set #14080 which measures at 108mm outside diameter. Got me thinking. Measured the Eibach springs #140348 which are on the car now and measure at 131mm outside diameter. By the way, I'm the original owner. No accidents and no other mods. With the 205/50R15 on the Konig rim bolted straight up, no spacers, I have about 3/16" clearance from the sidewall of the tire to the cup on the strut cartridge where the bottom end of the spring sits. Checked the boxes the rims came in from Summit Racing and their marked right with a +20mm offset. Just a note, spring is in contact with tire whether car is elevated or not and the car does use lug bolts. If I still had my stock springs I would put them back in. Nowhere to be found. Wife must have tossed them. Ha! The RB springs seem like the next best thing.

stuberg

Looked up in my trusty 1984 Mazda shop manual that the coil diameter for the front springs is 123mm and the rear springs are 105mm. Would have guessed differently by available spacing.

Good to see the mystery is solved. Who knew eibachs were so wide.

Isnt it 59.4? Not 60.

On to the next mystery! Thanks for the moral support and input.

Its 60 so it can clear the 59.4 interior dimension. If it was 59.4 it would never slide over it. Right?

Back when I ran Rewinds I used ½ inch spacers all around with either 205-50-15 or 225-45-15. With enough effort you can get 245-40-15 tires under the fenders but it requires careful planning, 2.5 inch coil overs, and a lot of hammering on the fenders.
