I really find the plastic too soft, its got more of a foamy feal, rather then the more crisp xray or tamiya carbon reinforced parts feal, but they do not break easily, I guess a lot of flex built in, I am going to mount some 418 suspension on the car and see how it handles, like I said earlier it is a direct fit, no modifications required. The trf shocks as well are a direct fit and proper lenght and you get one of the best shocks in the business, my car handled a lot better then the stock shocks, but I tend to put trf shocks on all my cars anyway, I think this car with the correct parts will be very quick
