hey guys. I'm in need of a camber kit for my 8. The suspension is stock, but the 19" rims i have on the rear make my tires tilt in just a little bit. Because of that, the tread is being eaten up much faster on the inside than it is on the outside.

Just wondering as to which ones are out there and for how much.

RX-8 Adjustable Camber Plates

We built these 6063 billet aluminum for our Project RX-8 with great results. Really stiffens up the front end . We now stock these for the latest Mazda RX-8. Comes complete with all needed hardware.

 

yea, but what about for the rear?

 

Don't know

 

it's the rear i'm most interested in ATM.

 

If i'm not mistaken there is a factory rear camber adjustment. with factory ride hight you shouldn't need an aftermarket kit. your local alignment shop should be able to properly adjust your camber for you.

DON'T do this yourself by eye. when you adjust your camber you also affect your toe settings. ALSO, the rear suspension is designed to have a certain amount of negative camber for proper handling. with the 19's and lower profile tires with stiffer sidewalls you obviously can't get away with as much negative camber on a daily-driven basis.

How much extra chamber adjustment can you have with aftermarket ones?

My question is really: What is the limit of the stock chamber adjustment?

Thanks

EDIT: The manual said 1 degree tolerance ... but I don't know what it means???

 

i saw another guy w/ the same size rims as i on the rear, and his wheels weren't tilted inwards like mine were. i forgot to ask him what he did w/his wheels. shoulda done it when i had the chance.

 

As has been alluded to, you should have plenty of camber adjustment in the rear from the factory to get it dialed in like you want it. If you've done something fairly radical with the suspension you might have to explore other options, but otherwise you won't have any problems; just find a good alignment rack with a tech who understands how it works.

The RX-8 suspension is both very sophisticated and very adjustable, as you can adjust camber, caster and toe up front and camber and toe at the rear. And the adjustment ranges are fairly broad, allowing you to compensate for any 'normal' suspension mod. About all you can ask for, really.

 

Correct me if I'm wrong, but I do believe adj. camber plate is only for the more traditional struct assembly. Since 8 have the upper and lower A-arm the camber plate will not be applicable.

 

I was thinking the same thing RotaryZZ; it doesn't seem like a camber plate could have much effect on camber in an RX-8. Could get rid of a bit of compliance and firm things up a tiny bit, but since the shock/spring assembly isn't a locating member of the suspension (in the front or rear), I'm not sure how it could do much with alignment angles?

Irrelevant to the thread since we're talking rear camber anyway, so we'll let that rest for now .

 

My rear tires have worn poorly from the day I owned the car (bad interior cupping).

I recently went to NTB and told them specifically to allign the car and take out as much negative camber as they could.

It started at -1.6 and ended at -.7 for both rear wheels. The technician said that was the farthest he could go with the adjustment. That angle should work fine and cut down significantly on my inner tire wear.

For the record, my rear suspension is stock. And on the day I had the allignment done, I had a half tank of gas and my audio equipment which is about 70lbs in the trunk.

man i really need to get my aligned too!!

 

need to fix this problem with my car also

 

Any more ideas in regards to this topic?

Im finding it hard to find a camber kit or even a bump stop for my RX8.

I just got my alignment done and I instructed them to remove as much camber as they can so that my tires start to wear more evenly.

I've spent some good money of my Nitto NT555 tires and I only got to really use half of it because the car is eating up the inner rubber.

Can someone provide some more options or ideas or hell even some places that even provide a camber kit.

Thanks!

 

I run RPF1 18x9.5 (265-35-18) Tires btw

 

You don't need a camber kit. There is plenty of adjustment to get the a proper alignment on your car without any need of a camber kit. What suspension are you using anyways?

What your problem might be is you may have too much Toe in on the rear which is also a big factor for tire wear. Try posting in the regional forums for a recomendation on GOOD alignment shops near you.

As for bump stops, check with Fat Cat Motorsports.

 

I have changed my suspension as well.

I have Megan Racing Coilover Damper Kit Street on my car.

I just got my alignment done and they said that they removed as much negative camber as they can. The tech advised me to pick up some bump stops to help with the camber.

Is that right?

 

There is plenty of camber built into the suspension. From the factory, our cars start with about .5-.7 negative in the rear and .25-.5 in the front.


When I dropped my car, I had them put more negative camber in(preppin for lower offsets). The tech that did my alignment said the range in the rear is from about -.5, all the way to about -4.5.

 

Holy crap

 

Not saying that they are needed but here they are.

Well I trust you guys more than some tech I dont know.

I'll be buying a new set of tires and I'll have the shop check to make sure my wheels are as flat as they can be.

I'd like to actually use up most of the tire on the next set I'm about to buy.

Thanks for all the feedback peeps.

 

All you need to do is get it aligned. there is no need what so ever for a camber plate. I had my car adjust recently when at the dealership. i think i went a bit too aggressive but I had the stock wheels on and will be putting my 19s back on soon which should change everything.

 

just got to a good performance alignment shop not some national chain tire store.
If you're willing to pay $100 or so, they can take most of the camber out. (if that is truly what you want to do)

 

Hey Jedi

You're local...

Do you have a shop in mind that I could go to for an alignment?

I've been dealing with Scher Tire and their Lifetime Alignment deal for quite some time now...

If I need to spend money to get this job done right, then that's what I gotta do.

I don't ever plan to hit the track anymore, nor do I race around the streets for fear of expensive tickets.

So yes, eliminating as much negative camber is my goal.

Thanks!
