as for engineering... bleh, engineering is overrated... the VASS who signed off an RB26 in a 180SX I took to him didn't even check to see if the brakes met the requirements for the powerband (are CA18 brakes suffient for an RB26?). Its all about how they feel about your car, there's nothing scientific to it. The only thing they can do is make sure that your car meets ADRs and emissions.
