simple rule, if it was 2wd, regulations say it should stay 2wd. if it was 4wd you can lock out 2 wheels (if im not wrong) no issue, can reinstall 4wd no issue jugak. Just 2wd stays 2wd...That means those CK Lancer converted to Evo 4WD is illegal? Always can see some of these converted Evo 5 and 6 being sold. Claims that they are fully converted with 4WD.
theres another form that allows you to go pass the 25% limit... dont fully understand how it works tho.... (or if im not wrong, you can convert in steps, 25% at a time, applies for cars other then those protons)if endorsed before enforcing 25% limit is ok. For later one, insurance will scratch head.
