this is exactly what I experienced
T4 is not that "undestructable" at all.
I bought T4 because most C-Hing here said it is "硬度高"
I bought TRF418 because "TRF41X series" is WORLD CHAMPION CAR.
However, compared T4 2014 and TRF 418
BOTH ARE "現時車速, 再硬都一樣爛野,只在爛幾多野"
T4 would take a heavier hit, but still "再硬都一樣爛野"
Indeed, HOW you drive determined how many times and how hard you get your car HIT.
A car with BETTER handling can "minimize" your HIT.
I suggest, you tried someone T4 2015 and TRF 419
see which one you "FEEL" better with your "DRIVING STYLE".
