camber plates
#1

I have noticed after just 2 DEs that the outside edge of my tires are wearing rapidly. Would camber plates alow me to adjust the camber out so that tire wear would'nt be as bad? Would it improve the handeling and turning of the car? Anyone know of the most reasonably priced ones on the market? So far I have coilovers and sway bars to improve handeling.

if you are wearing the outside edges, you could have a couple of things going on



more than likely your toe is off - also, your pressures may be too low, causing rolling on the tires - low spring rate up front can do it too



camber plates can allow for more camber, but frankly these cars tend to have too much camber far too frequently, because the chassis flexes and allows too much camber change - using the camber plates to add a degree or two then results in huge camber mismatch left to right under cornering load



the first thing i would do is get a strut tower brace in there to limit the camber change (you didn't mention one, so i presume there isn't one)



then, check the toe setting - it should not be more than about 1/4 degree total, and preferably about 1/10



then check your tire temps and find the pressure that evens that out

You don't need camber plates to adjust your camber - the eccentric bolt on your strut bottom does that. The adjustable camber plates are not really suited to adjust camber for specific events. I fitted mine with the intention of increasing camber for track days but as you increase the camber you drastically affect your toe in (or out, cant remember where the steering rack is positioned now), so it is not feasible unless you are able to adjust your toe settings to compensate.



However the upgrade to a monoball top mount is something i'd recommend. I upgraded when I fitted my KW's and the ride quality has not been reduced as much as you'd think but the turn in is razor sharp - and i'm still on stock bushings. Before i really noticed the low gearing of the steering rack but now I hardly notice it. I fitted the Racers Edge mounts. I guess with a cab you'd really need to brace the front end with upper and lower strut braces as I would imagine it would increase chassis flex considerably.

What is a monoball top mount? Where is that available?

When you refer to camber plates I took it to be in reference to the adjustable camber plate strut mounts that replace your rubber strut top mounts. These plates have a rose joint or ball joint where the strut bolts in and therefore have no rubber to absorb vibration. The stock rubber top mounts can give under hard cornering therefore don't maintain the geometry of your front suspension thereby dulling the responsivness of the steering feel, but on the upside they provide a more ride quality. The monoball top mounts have no vibration absorbsion at all but don't give under cornering forces. The result is a suppolsidly harasher ride (though I didn't notice a significant reduction in ride quality) but much more responsive steering and better front end grip because the suspension geometry is being maintained.



Mine are Racers Edge plates - you can find them at www.racers-edge.com



Not sure if this is what you were referring to.
