Ok I have a 06 Evo and when I accelerate hard in 1st gear only from the passenger front area I hear a very weird noise kind of like rocks getting kicked up. I am not to sure what it could be it is a intermittent issue. When I do launch it it usually seems to spark it, it is not constant and only in 1st gear higher rpm's. I do have re01r's someone said it could be rocks since the are pretty sticky tires but I think it's somethig else any ideas?
