They called him mellow yellow.
Yea mate I know a few guys who have done this but they all drive saxos! lol
Sorry mate couldn't resist, If your intending using your S3 as a regular track car then a cage might be worth while, a proper one may well save your life one day, if so worth every penny. If you were to get a full cage & not just a half/rear one it should increase the chassis rigidity some what aswell. I have a funny feeling that because the saxo crew seem to have turned cages into a styling mod these days there will be a few ****y ones out there so best buy from a reputable company preferably with a racing pedigree.
