Post pictures of your Astra K here
Nice mate, i got the same colour, i am looking at the full kit on https://www.magnatuning.com/en/product/ ... o-Body-Kit. The sides are the same as yours how do these go on ? they just stick on with some tiger seal or did you have to drill holes ?.
The full kit what i think just all clips onto the car, drill holes in the front bottom bumper to screw the front splitter on, and looking at the rear bumper that just replaces the black plastic thats already on. (what you have done on the rear where exhausts are with the custom).
These are the rims that i was looking at 18", (got 17" on atm as standard) might need to lower the car just a bit but ill have to see,
