FC rear camber link rod, version 2.0 - on car adjustable

here is some pictures with the revised prototype installed with the corrected length, keep in mind my car has been lowered about 2" from stock height and had about 4-5* of negative camber to start with, i left the adjustment at about -.5 degrees but the rod has more adjustment, it is really only designed to take out about that much camber. if you need to add even more camber, say if you have the car lowered as much as possible then you would need additional camber adjusters for each lower lateral arm such as the ones mazdatrix sells.

the rod itself, keep in mind the adjusters will be located at the other end of the rod for ease of on car adjustments:


initial adjustment with the rod at stock length zeroed out:


after adjusting the camber to a more reasonable stock level:


lowering the car adds negative camber where the wheels look like an inverted V or / \ shape. raising the car from stock adds camber such as a V shape or \ /. the rods i am producing are to correct for negative camber adjustments, in other words to correct for lowering the vehicle. i can make rods to recude camber for those who are raising the cars for racing such as rallycrossing but those are few and far between so for now to keep as much integrity to the rod as possible the initial prototype design is for lowered vehicles.

shortening the rod length increases camber to correct for lowering the vehicle, increasing the rod length reduces camber for raised vehicles.

the rod itself is located to the left of the differential pumpkin attached to the rear of the rear subframe of the car, you will need 2 17mm sockets and 2 3/8" or 1 1/2" and 1 3/8" ratchet to remove it. the topside inner bolt is a little difficult to get to so i suggest breaking the outboard nut loose first before worrying about getting a socket on the inboard bolt head to keep the bolt from spinning. i will get more detailed pictures soon when i make up the procedure list for the rod.

for now they are ready to produce so those who can send me in their cores let me know, those who need the premade rod i will need to make a list for the core return list will have to start now as i only have a limited amount of cores to build and ship out while waiting on cores to be returned.

so i will have 2 lists:

list for those who need a premade rod, daily driver's or cannot remove the rod until they have one to reinstall or have no spare rod on hand.
1.
2.
3.
4.
5.
6.
7.

list for those who can send in the rod while their vehicle is down for repairs or those who have a spare rod on hand to send in.
1.
2.
3.
4.
5.
6.
7.

the lists are for the on car adjustable rods, as there seems to be little to no interest in the off car adjustables.

final cost for the rods will be $56 plus $7 shipping and handling to the lower 48 states and an additional $10 to those on the first list who will not be providing a core or will be returning one at a later time.

payment can be made to my paypal address at: [email protected] in the amount of $63 if you are shipping a rod out first or $73 if you have no core rod to supply or will be shipping one out after you recieve the premade one, once i recieve the core in good condition i will refund the $10 core charge.

at this time i only have 3 cores to send out at a time until i find more so if you do not pland to send in yours to be modified and sent back please send me a PM first so i can give you a timeframe if the rods i have in stock have all been sent out and i am waiting for returns so that you are not wondering why there are delays.

I've found that using delrin/hdpe rear diff bushings and/or subframe bushings will significantly reduce the usefulness of the camber rod. I had to buy the individual links instead to adjust my camber

that is another point to make a note of. the induvidual camber rod adjuster(the one being sold here) is really designed for use with the stock mazda rear subframe bushings, not solid or hardened bushings. stiffer bushings will put alot more stress on the rod and it will not adjust fully or much at all.

Sorry 'bout the hijack, Karack! I spent 80 for my GC adjuster 3 years ago, so this is a steal compared to it!

i don't have exact degree measurements since i don't have an alignment machine here at the shop but the look of the car was aggressive enough that it appeared to be in the -4 to -5 degree camber range, which can be taken out to 0 with the adjustable rod. as you can see by the pictures the top of each rear wheel was cambered in almost 2" and can be taken completely vertical after adjustment.

basically the rod will easily correct for moderate to moderately extreme drops in ride height, if the suspension is bottomed out however i don't believe it would cure that much camber. that is a rather rediculous drop amount anyways, as you sometimes see on those showcars/drift cars with stupid amounts of camber in the rear. i don't have a set of stock rear struts any longer to see exactly how much of a drop this will cure camber wise, nor do any of the websites that sell the rods list the amount since it is not a perfect science and depends on the initial camber of the car, worn bushings will also affect the amount of camber you will get.

the car and rod i am using for this example are all original with 208,000 miles on them, all the rear suspension short of the HKS coilovers have exactly that amount of miles and age from 1987(it is my car so i know that is a fact).

unfortunately i don't have the time or desire to get exact figures for the example, the rod is priced accordingly and the results appear plenty satisfactory to me even by crude initial/post measurements. the wheels pictured are 18's on 45 series tires with no rake and about 3/4" of tire to fender gap.

side note, the convertible rods have slightly larger bushings so if you have a convertible please specify and i will let you know if i have any cores in stock otherwise i may require your core to modify first. it is pictured in front on the right side.

for now they are ready to produce so those who can send me in their cores let me know, those who need the premade rod i will need to make a list for the core return list will have to start now as i only have a limited amount of cores to build and ship out while waiting on cores to be returned.

the front differential mount will try to work against the camber rod if you are using a hardened or solid one. you can reposition the front mount by loosing it up where it bolts to the subframe prior to adjusting the rod length then retighten it down. this my be wise anyways prior to doing a major camber adjustment in the rear, my mount was a bit old but now i'm getting a clunk in the rearend on decel so thinking the shift in angle promoted the front mount to rip further or completely, but then again the car does have about 350WHP on some pretty old mounts so it probably was overdue for replacement again(working on a new diff mount with replaceable rubbers cause i'm tired of the OEM's crapping out and costing a small fortune).

the rear differential mounts make no difference to the camber or rear subframe.

for the front diff mount, what if you replace with OEM and use a pinion snubber? will the snubber affect the rod as well (I think they are just rubber, right?)?

Just to make sure I understand, the OEM front diff mount poses no problems with this rod on its own right?

nope, the differential position will remain the same but the mount will twist to a small degree as the subframe is rotated.

both the rods in list #1 have been shipped. and sorry for the poor packaging, the worker said it was the cheapest way to ship them as i had them packaged raw. i have no idea why they have flat rate boxes when they do not honor their quotes(they quoted me over $10 all said and done, i still ate a little in shipping to do it how it was done)...

it's a rod designed to take out camber, I would think it could withstand a little banging around inshipping

they're wrapped in cardboard but i still was expecting to toss them in a flat rate box on top of that with the reciepts, which i had to jam inside the sleeve i wrapped them in.

they're adjusted loosely to the stock height, shortening the rod length will increase camber for lowered vehicles. they are adjusted at maximum negative camber at the factory lengths the way i have them set up. i haven't written up a procedure for them yet so that will get you first guys the jist of what needs to be done. just don't overdo it with the adjustment, cranking it down until it is difficult to adjust to compensate for rediculous drops. the rods can collapse more than enough for most camber needs.

i do, in fact i ordered a bulk set of right and left hand nuts recently so i have materials to modify dozens but only have one core left, so until i can find more i still require them to be sent in to be modified versus exchanged.

one core for each coupe and convertible left. the vert one is already built, the coupe version is unmolested until someone orders it or i go to the wrecking yard and get more cores.

anyone who can pull their rod and send it to me requires no cores on my end as the supply is dependent on you. so i can build these at any time, only those who daily drive their cars must do the core exchange. these do not take much time at all to put together so turnaround time isn't ever really an issue, in most cases a week or less from you to me, modified and back to your door.
