I dunnow.........Went back through several years of pics of my Crimson Pearl STS........without the buff/cream stripes it would look sort of monotonous and "slab-sided". Without the accent the car looks shorter (in length) and fatter.
I used a rubber eraser wheel ($25 at Advance) and a DeWalt 18v drill and did it in about 20 minutes. I might get another put on, but the original was all falling off and what not so it needed to go either way.
Car looks good both ways. 3M eraser wheels are the best!
I am firmly anti-pinstripe EXCEPT for our 01 SLS. This is the only car I have put them on in nearly 20 years. It is a Cashmere car with black subtle pinstripes on the sides only (not rear). No fancy ends, just pulled together to for a nice "V". No idea why, maybe as submariner indicated, it elongates the car to a more pleasing perspective. However, as stated, yours looks great either way. Then again, yours has different dimensions than mine too. Leave them off for a while and see how you feel about them.
