Both! It is good to use a tweak station but on that you can only see and adjust the tweak in the complete car. Try rebuilding the car every once in a while and check each (flat) part if it still is that way. The motorplate, left bulkhead, lower pod plate, main chassis... All parts that should be FLAT and if they are not they can cause tweak which offcoarse you can adjust but they are not 100% so the car is not 100%. Check this every now and then and replace parts when needed...
A good way to check if a part is still flat and straight is to put it on a glass plate. Glass is really flat and so you can see or feel if a part is bend...
