Well I finally took a good look at my suspension and brakes getting ready for another track day and am glad I did.

This is what I saw



As you can see the rotor is offset about 3mm to one side of the caliper. Up until this point it has not been a problem, but as the pad wears down the pistons on one side of the caliper will be over extending themselves and can cause an issue in pad wear or overheating of one side etc.

My options are to:

1) space the rotor outward 3mm using this



2) machine the knuckle down 3mm so the caliper sits further in

3) machine the caliper mounting surface 3mm so it sits further in



I am looking at doing #1, unfortunately Spoon only makes those rotor spacers in 4-lug (designed to space the rotor out for non 5-lug hondas) so I will be getting some machined. Now most of you are thinking, "but dude you have 5-lug, so why are you having an issue?". Well turns out, when my car was stolen they stole my 5-lug, so I purchased a JDM 36mm set from a local shop. Unfortunately it looks like the knuckles were originally off a non Type-R car and that is why I am having the rotor offset problem.

Can anyone recommend a machine shop to get these made out of CNC aluminum? Obviously they need to be perfectly flat and also fit around the hub and inside the rotor hat perfectly. Alot of my evo buddies are saying that running a spacer on the rotor may cause the rotor to run out of true especially if dirt etc gets in between. Any recommendations welcome.

 

i would run a spacer since it seems to be the easiest and cheapest solution. i see it as being no different then running spacers for rims.

its also reversable as opposed to machining metal off the knuckle or caliper

 

^^that's what I think too, but my evo buddies said that it could cause the rotors to run out of true over extensive use and eventually I would be changing rotors more often etc. or getting some vibration over time. Sigh...I am also considering just selling this front 5-lug knuckle and getting a USDM ITR knuckle to replace it and just be done with it.

 

How is it your calipers have an issue and others don't? What are you doing different?

I would say it's the way they are installed, not an issue with the rotor itself. PM user BlueR who might have more insight on this, but I'm pretty sure it's a washer issue on the caliper themselves.

In other words, move the caliper by shimming the bracket/caliper not the rotor.

Edit: Read more of the post and my thoughts still stand. Fix it the right way, not by shimming the rotor. Brakes are UBER important, especially on track. Do it right, the first time and forget about it.

 

No...i think you misunderstood me. The knuckles on my car I bought second hand. The calipers themselves are perfectly fine and would work on any OEM ITR knuckle. However, the knuckle I have on my car now I think was a non- 5-lug knuckle that was converted to 5-lug. Therefore I am having the same rotor offset issue that all other four lug people run into when using spoon calipers.

Spoon sports makes the rotor spacer for 4 lug cars, so I am going to have the 5x114.3 pattern machined onto that same rotor spacer.

 

What car is the knuckle from? Maybe I will buy them from you if the RSX axles are a direct fit...

 

I'm trying to figure that out. It's got "9JL" stamped on the knuckle

 

Which track day are you planning to attend? Are you going to the limitless event on August 17?

 

HAHAHAHAHAHAHAHAHAHAAHAHA

 

^^....alright troll someone else's thread please thanks...ahhh ignore list...awesome

 

your still having problem..
im not telling.
hahahhahahahhahahahahhaha

 

You guys know he lives in Cali to and will be at an ITR meet someday.

Shimm it with some washers, there is a post about on HT, I just can't find it.

 

Yah honestly don't know what's wrong with those guys, but whatever I'm over it. I just added them to my ignore list.

 

do you have the washers that spoon provides for the calipers? i dont see the washers?

 

Anyway, I apparently was sold front knuckles that were not ITR ones. Unfortunately, they all look the same. I didn't know until I checked. I didn't even realize 4-lug people had to use a spacer and had no idea what a spoon inner spacer was. Also never heard of anyone spacing out a rotor. You can call me a nub, a kid, whatever you want to call me. It's all good as long as I get the car fixed. I never said I knew everything about ITR's and am glad to learn new stuff.

As you can read I have other cars as well, kinda hard to know everything about every single one. Car has been performing fine, but I think it would eventually cause an issue.

 

The washers push the caliper outward. It would make the problem I am having even worse. Initially I was thinking that the washers were in there and causing this problem, but as you can see there are no washers there. So that means my knuckle was a 4-lug knuckle.

 

bingo................

nothing to do with the sale. you were informed on the wheels. so dont mislead people.

i just hate expert hardparkers. kahuna knows.

i will tell it to your face if i think its bs info.

yes i do like to act immature and childish even i am a decade older than you. makes me feel young....hahhahahahhaha

 

i love infraction too.

 

Well if you are such the expert, then you would know the washer would space the caliper OUTWARD. If you look at the pic, the caliper is already too far outward. So you want me to fix a caliper that is too far outward, by putting a washer to put it even more outward? I'm not a genius here, but that won't work...

Spoon makes the inner spacer or rotor spacer for a reason. I posted a pic of it. This problem all stems from me not knowing I received non ITR knuckles. The only way to get the rotor to sit in the center of the caliper for my specific situation is to mill the caliper, mill the knuckle or space the rotor. None of that is BS info. I am probably one of the only people running a non ITR knuckle on their ITR, I never said that everyone with an ITR has to do this. Far from that, I'm probably one of the only ones that has to do this as I stated in my thread title where it says:

"Need a spacer behind the rotor (in my case anyway)"

Nowhere did I state everyone had to do it. These will bolt straight on to an ITR with USDM knuckles or 98+ JDM knuckles.

 

ok if you say so. you do know that honda recycle parts. your caliper will fit other honda cars. its not your knuckle the problem. ask. right now you sound like an expert. it only take 10 minutes the most of common sense to solve the problem and a trip to a retailer. dont assume.

 

How are you going to get a caliper to sit farther inward by putting a spacer between the caliper and the knuckle? I don't need to be a mechanic to realize that makes no sense.

The caliper will not sit any further inboard than it already is. In my first picture is the passenger side caliper. So the caliper is sitting 3mm too far out, yet it's mounted straight onto the knuckle with no washer as you can see on pic number two.

Washers space the caliper further out. I need the caliper to sit further in, or have an alternate option of pushing the rotor itself out. I have a relatively unique issue. I wish it was as easy as putting on a washer because it would be much cheaper than my other alternatives.

And yes, cmeot these calipers will fit on other cars. But some cars require the 3mm spacer made by Spoon themselves. Here is the description:

Maybe this will help everyone realize a washer for the caliper unfortunately will not help me...

 

Why hasn't anyone suggested the obvious...get the proper knuckles/hubs for your car. Instead of the band-aiding, just fix it right.

You've already dropped a grip on Spoon calipers and Volk wheels, so just keep going so there are no surprises and everything is how it should be.

Personally, there is no way I'd do what you're trying to do, but that's just me.

 

Todd, OP... read the 3rd post... it's from me.

Last line... Do it RIGHT, and then forget about it.

IMO, just replace the knuckles with the right ones. Quit half assing it and playing with shims and such. Brakes are the most important thing on track, and if your doing track days I say skip one, take that money and buy knuckles and fix this issue right, one time and move on.

 

^^Yah that is good advice. I still need to identify what knuckles I have on there right now. I know that everyone running spoon calipers with their stock knuckles and ITR sized rotors are using this spacer, so it works but it isn't ideal.

Does anyone know what cars share the exact same knuckle as the ITR? Looks like I need to start shopping...my axles are 36mm too, so I'd have to pick up some stock ITR axles as well....sigh
