Actually Toby thats not a factory front spoiler.....thats my car (should now read was my car) I should know LOL
Its actually a AE92 front lip spoiler, I believe they have been discontinued in stock from toyota now but they were only about $20 for the 2 parts (L & R), you would then have to cut and shut the centre of the 2 so they are the right width and some people bolt them upside down and cut the number plate section flat, I put it right way up and left it standard.
if you mean the lower lip like on Mick's car,you'll have to get one off of an AE92,as they are no longer available from toyota.
I have tried to get one several times in the last few months,and they are no longer in the warhouses. you may get lucky if you pester enough dealers though. one MAY have one lying around out the back that they've forgotten about.
