right im new to this site this is my first post so bear with me. I have owned a celica gt i think it is an ss11 cause it is very low how do i tell ? also do you think i should remove my rear spoiler will it look better? my car was imported all the mods were done when i bought it , their are some engine mods they are - hks air intake jasama downpipe and fullstainless exahust, this may sound impossible bu ive had the speedo round to 165mph i know the speedo is about 8mile an hour out the previous owner told me but that means i was doing 155mph+ could this be right as i say i dont know too much about the car would appreciate some advice.. oli

From what people know here, you doing 155 MPH is not right. They're trying to figure out why it's saying that.
