So here's the good news. I've got a great deal on RSR springs as well as a TRD rear diffuser. The bad news is my dealer says I would void my warranty if I install any of those products I need some suggestion guys, should I give up my warranty or should I just keep my car in stock form?

 

Your dealer is Alfuttaim?

 

Unfortunately, yes

 

i think its okay that you have these intall in your car because i have installed INVIDIA mid-pipe + AFE cold air intake and i do my service in the dealer and they said nothing to me !! if the parts thats you will install will cause any problem your warrnty wont cover it !! but what would the diffuser do to you car LOL ITS ONLY A STYLE MAN

 

+1 for just do it! i have aFe intake and ARK cat-back and no problems from the dealer.

 

Thanks for the response, guys.
I'll get the parts and install them!
