Skunk2/Eibach both make good quality Camber arms AND lcas.
D2 sell cheap rear camber arms, i have these, decent for the money.
Function7 are considered to be the 'daddy' of LCAs, quite expensive, but do look amazing.
People will tell you skunk2 are shite sometimes, this is only if installed incorrectly. They need tightened up once on the ground aswell as on the ramp.
