i had them put in a miami chassis, an excellent shop known for working on lowered suspensions exclusivley, i've got an is300 with coilovers on it i had over 3' negative camber in the rear and they were able to get it back into spec with no camber kit, they slottted the rear arms for more adjustability.
they really know their stuff,you pay top dollar for their knowledge,but their work speak for itself.
i 100% sure that the install is correct
