    Default Corksport Front camber plates

    Great news ,Corksport are developing front adjustable camber plates for our outrageous OEM tyre scrub.
    Yahoo this should help with tyre wear once installed.
    Initial sets being trialled by some mazdaspeed forum guys.
    Stay tuned.

    Cant confirm for 6 ,but if front struts are same as MPS3 ,i dont expect a problem.
    Check out mazdaspeed forum /gen2 / (wheels /suspension ). Someone who knows how to copy or link the details of corksport camber plates to this thread. Thanks.

    6 MPS doesn't have struts, so the answer is no, I can't see them fitting. The suspension in the 6 and 3 is completely different.

    Still, I don't see the point of adjustable camber being used to reduce tyre wear.
    Stand the wheel up and all you will do is wear the whole tyre out, not just the inner edge. You might get a bit more life, but not much.
    You will get far more life out of the tyres by removing the tyres from the rims and swapping left and right.
    By doing that the warn inner will now be the outer getting little to no wear, the old (good) outside edge is now getting the wear and your tyres should double its life.
    The $15-20 each to do that is far cheaper than new tyres or camber kits.

    I'd really only worry about camber kits if for some reason you can't get the alignment to specs.

    ok, don't shoot me, but why should we be happy about this? I thought our issues where just the rear...end...of the car...

    Nor have i, 30,000km on the tyres, if i did as i said (the swap tyres thing) i think i would easily get another 25-30000km. Only bought new tyres because i wanted wider and taller tyres.

    These camber plates are really to be adding extra camber, so you can go to the track and quickly dial in more camber. Not help with tyre wear. You shouldn't have too much problem with the front wear if you get a good alignment. Especially at stock ride Hight.

    ok, I am planning on coming down a bit over the next few weeks. Got some new suspension on order. May need to look at the US forums and see what they're all about...

    I read a few comments over there:

    Ground Control CC plates typically give you more shaft travel allowing you to run a lower ride height without sacrificing bump travel. In addition the caster adjustment that most of their designs allow for is a huge bonus.

    OEM alignment spec for gen 2 is too large a variance.
    OEM Front end has little or no camber adjustment at all and very little toe adjustment. Designed as original so as to benefit steering.Turn in .
    Oem rear has again too large a variance in camber. Again so as to assist rear end holding on to road.
    Currently 17000 klms and tyres are shot. Run 40 psi to front and 38 psi to rear ,tyres have been rotated every 500klms. (leelu,yeldarb,postmandan) from memory .
    I dont and many others dont want to have to spend upwards of $400.00 per corner every 20k .
    Fully understand that tyres need to be swapped over to alternate wheels, but the shoulders will still receive unwanted wear.
    This issue has been discussed many times on this forum as well as overseas, UNacceptable wear. We will never get very good tyre life ,as these cars have been set up for performance driving,but to sacrifice a minor amount of handling as most of our use is every day conditions not track, or trialing .

    I have to agree Paul.

    The oem suspension setup leaves something to be desired, and numerous tyre places have said the suspension adjustment is not adequate for properly dialling in the suspension.

    Personally I think the more adjusment you have, the better.

    Ok. You've sold me. Especially if you're lowering the car you'll need these more than ever it seems.

    I'm not for constantly replacing tyres. Who is? I'm on my second set now. I've done about 24000k's and had them rotated for the second time a few months ago. No word from the shop on how they're going, but no doubt they'll be due for replacement late this year.

    Surely if I combine a new set of tyres with this camber plate, then I can almost expect "normal" tyre wear?

    I've seen a few comments not in favor of adding a rear adjustment as well. Surely the rears need it the most.

    The front is not the issue. It's all in the rear, of the Gen 2. The Gen 1 has a different setup, so no issues arise when lowering.

    The rear has camber adjustment built in. It's the toe that can't be adjusted when lowered because it is designed as a single adjusment of camber/toe. Change one, you change the other.

    Camber aids turn in, but, increases tyre wear.
    Castor is what you need to save tyre wear and have good turn in response.
    Increasing castor also puts more load on power steering, because the car will want to drive in a straight line.

    Brad, I have rear toe adjusters here for when your car is lowered.

    Yes it does. But it is up to the owner to allow this or not. Just becasue Mazda say the front toe can be +/-3.0mm toe doesn't mean you have to have it that far out. When you go to the alignment/tyre shop, you should ask them what alignment settings you require.

    Doesn't need much camber adjustment at stock height. The little toe adjustment state doesn't make sense since the above statement says there is too much varience. Camber plate will not add toe adjustment.

    Dunno how front camber plates will solve this issue. Unsure of the relivence of it.

    Sounds more like a poor toe alignment issue than camber problems. Camber tends to effect the inner 50% of the tread. Poor toe will effect the inner 25%/shoulder of the tread. Not sure if you are looking in the correct direction for you early tyre wear issues.

    ---

    I thing have found within this MPS community is the lack of knowledge of suspension geometry. There is alot of "Mazda told me this, Mazda told me that." Or just a total lack of aligments by owners as most dealers to not include wheel alignments as part of a service. But somehow most owners think it is included. I'm not saying this in insult anyone. But it is true.

    If you want a good alignment. Go ask someone you know that hits the track repeatedly. They will be able to tell you where they get there alignments done in your area. As they need theres done correctly and to specificied specs.

    And if you are a certain few that get them done at a Mazda dealership. STOP!!! Get it done at a real alignment/tyre shop. Save money and get it done right...

    On topic.
    Most camber plates will add 20mm height to your suspension height. So be prepared for this if/when you install them. Will your suspension geometry be effected if your front ride height is adjusted higher by 20mm? Could be a killer for handling on a FWD car that needs the front axles lower than the rear axles.

    Beautiful, now we have a constructive /helpful thread.
    some very insightful points,from everyone and ProjectRacing, and yes the plates being discussed are only for Front end.
    I personally would not allow a tyre jockey do my alignment only a specialist.

    If it helps, Mazda Bundamba did my last alignment. I brought the data sheet along showing the results to the Fulcrum Suspension Day. The Fulcrum Guru thought it looked pretty good. He noted that they adjusted for the exessive tyre wear that's been common amoung the GenII.

    But the gist of the plates will mean more adjustment and therefore less tyre wear.

    I'll be heading to Fulcrum to do another alignment after Troys coilovers are fitted. I'll meantion this product and see what they say of it.

    Thanks Project and Paul for the advice.

    I think the "new" front camber plates would be designed to fit into OEM struts/shocks/springs, allowing direct replacement and no change to height.

    If I was to design something (as I do) it needs to be a direct replacement, not something that will require further mods to "complete" the fitment.

    Stock strut tops are 2mm thick surrounded by rubber to prevent noise and are a convex shape.

    Aftermarket strut tops are 4-5mm for the alloy plate, and another 4-5mm of the ball joint coupler. And then the diameter of the ball itself. All this is added between the spring top and the wheel arch suspension hole.

    I know Cusco for there stats that a 20mm increase happens when installing there products. And HKS/K-MAC etc all have similar designs.

    Different products will have different fitting issues. I was just making a buyer beware note on camber top plates. It is now up to potential buyers to ask teir questions and do their own research.

    a quick update on these. they look awesome BUT, You will need a 3-1/8" hole saw to enlarge the existing hole in the strut tower to allow the camber adjustment.
