I'm not sure in which way the plastics felt "soft" to you
We are confident that the plastics are some of the best out right now.... me personally I have 3 gallons on my car with every bit of the stock plastic, no slop and they dont flex nearly as much as half the stuff out there.
The only true test for any car is to test one out with a good setup.... thats when all the bench racing and hear-say ends, our car is solid top to bottom, inside and out
