i tend to forget that this accord forum is not gen specific.. the shim style camber kit is perfectly fine.. i use that method on my civic..
it can also be used for accords previous to 98.. but the 6th gen requires an adjustable arm.. as for breakage, i've had mine for over a year and it's been through numerous auto-x's and track events.. the factory endlink bracket has been breaking more than anything..
if there was a choice, i would recommend the shim method too since it's very inexpensive and practically impossible to get knocked out of its setting.
