about proton crack firewall u know la the firewall very2 thin...even if using racing clutch (hard to press clutch paddle) also results on cracking the firewall
another famous area for cracking was at the fender chassis (between the strut housing and firewall)..this problem i use UR fender bar to reduce further damage..
*in this picture u can see clearly on crack at exactly above the UR fender bar
*another spot of normal crack for this kind of car was near the bonnet rubber lining (top left in picture)
this shows that area have been flexing from the day it rolls out of factory..metal fatigue (worse if use adjustable suspension with harder spring rate)
