K12 have huge arches, they can accomodate much bigger wheels and still look good. Personally I think 15s are too small. I bought some 15 inches Team Dynamics Pro race for my k12 and it looks like a 4x4. lol. If it is the appearance you are concentrating then bigger wheels and lowering are a must.
And is it me or your side stripes are not level? It seems to slope upwards towards the front. i am sorry that's how it meant to be.
honestly if you cant justify spending 300 quid on a 2.5k car then what the point in modifying your car there are poeple on here that have threw more into there car than there car is worth
also who is puting your struts on for you as that seems well expensive mate in all honesty i would do them your self get a mate that has some tools and do it with him it will take you probs half an hour a hour at the most
haha 4-6 hours are they drunk lol will take you no longer than a hour mate i have a 2.5k car yet i have have spent loads on mine you will never make your money back on modifying a car so its all down to what you want to do to your car
