Hi

After some searching about camber plates I have become more confused than anything else. In some threads it is discussed that camber is not adjusted by the top shock mount on the RX-8.

In other threads it is mentioned that camber plates are for sale which would indicate otherwise. However I am having trouble finding a place that sells camber place.

Originally my problem is this. I have maxed out the negative camber to -1 in the front. I want it to be -1.5 or even towards -2 to even out the wear on my R tires for track use.

Does anyone have any idea other than camber plate to achieve this or is camber plate the way to go. If camber plate is the way to go, please advice me where I could get a pair.

Thanks in advance,
Per

I haven't seen any camber plates for the car. How about lowering your car some more so you can extend the A-arms further outward. They are the only way to adjust camber on our car as far as I am aware. What suspension are you running? and drop? I'm surprised that -1 is a max.

PerSmitt

I'm planning to get Koni yellow shocks. I had hoped to continue with stock springs. Currently the suspension is completely stock and no drop at all. This is part of my planning for my winter project. If I can't race on the track during winter I will at least have to prepare the car for the next season.

JIC magic carries camber arms thats all i have seen so far.

-1 is not the max. My fronts are at around -2 and thats not near the max

PerSmitt

How many adjustment points are there for camber in the front? The tech only found one bolt to turn that pushed the lower arm outwards. It is possible he is unfamiliar with the procedure how to set the camber on the RX-8.

Actually after more research i found this section about camber adjustments in the service manual. I found the service manual here: http://pdftown.com/Mazda-RX8-2003-Service-Manual.html

Sport suspension

Vehicle height Camber
361-370 {14.2-14.5} -0°45'±1°
371-380 {14.6-14.9} -0°25'±1°
381-390 {15.0-15.3} -0°06'±1°
391-400 {15.4-15.7} 0°11'±1°
401-410 {15.8-16.1} 0°26'±1°

It seems to indicate that you cannot get more negative camber than -1.45 unless you have lowered the car further. Have you dropped your car anything imput1234?

hmm, if ur aim is -1.5, I don't see -1.45 being a problem. if so, grab some racing beat springs. Drop is .5 inch all around and you should be able to camber more from that.

PerSmitt

That is a bit along the lines I'm thinking now. When you lower the car can you adjust the height you lower it or if you want to lower it further do you need to buy new springs?

And yes if I could reach -1.45 in the front I would be happy, however I only reach -1 in the front. I think my ride height is higher than the lowest one in the table.

they call them camber plates, but they're really just pillowball/spherical bearing mounts, there's no adjustment like a camber plate, they just bolt on like the stock top mounts

I have -2 deg front on OE springs ...

PerSmitt

Where can I get those? I have been searching on google for "camber plate RX-8" with no luck.

I assume they are just like normal bearing mounts but with the mounting point further in towards the center of the car to give more negative camber.

Btw, about the Koni yellow shocks, I was just told by Koni Sweden that I had to remove the shock from the rear of the car to adjust stiffness. That sounds like a lot of hassle considering the rear shocks are more difficult to exchange than the fronts.

yeah, but you will probably set & forget it, they can be converted to externally adjustable but you still have to drop them down to reach the top adjusters, they don't have to be disassembled like the std ones though, it will double the cost plus shipping from the US

you can get OE mounts converted to bearing mounts from Speedsource. I've made quite a few for people too, but am too busy at the moment. However, I don't really recommend them for your application based on our PMs. They're another "serious racing" part; more maintenance intensive and harsh riding than you want for the street

PerSmitt

Well I might have been unclear about the reason for wanting -1.5 to -2 camber and that is because I get uneven tire wear on my front Toyo R888s.

I have one more predicament, I have the RX-8 as my only car and a girlfriend with backproblems that demand a soft ride. I had been hoping on the Konis to have them easily adjustable to softest setting for street use, but it seems like this will be difficult to achieve. Also if I need to lower the car to get the extra camber I would need stiffer aftermarket springs which would make the ride stiffer for street which I want to avoid.

Thus I start to turn to another route: Bilstein PSS9. Sure it is costlier but that is ok. You can set the stiffness to real soft (even softer than stock according to some people) and you can adjust the ride height. It seems like the all in one solution for my problem.

Does anyone know or have experience with this kit how to set the ride height and stiffness? I assume the stiffness is easily adjustable, but ride height. Must it be adjusted during installation or can it be done after installation?

So, is that girl friend still around?

Never buy anything or adjust... based on a girl friend's comfort. I'm guessing she isn't around anymore. Am I right?

Those of you running more than -1 degree of camber....
What drop are you running?
What caster are you running?

I read that you need a soft ride, more camber, and are tracking...

I did TIEN H-Tech springs. Front drop is just over an inch, and they are progressive, so still soft. The H-Tech is the "Luxury Master" line. For Shocks, I did the Tokico D-Spec. They are adjustable on the car, front and rear. There is a good DIY out there. You just need to get the extension cables for the rear. You can adjust the fronts with the factory tower brace installed. I use 2 turns at the track, and then back them all the way out to 7 turns for the street for a nice soft ride.

I can get -2.5 degrees in the front on both sides, have a soft ride on the street, and the car got noticeably faster at the track. I just added sways, and that helped even more.
