Hi Mate sorry to hear about your car glad you are okay, I have the exact same colour car and the exact wheels as yours, except mine are diamond black centre. I run 285 x 30 x 19 rear and 265 x 30 x 19 front and the ride is perfect, they are Toyos and set me back £700 delivered for four I also had my cambers changed, not because of the tyre size but because of roundabouts
Id also suggest a body kit will be cheaper than replacing oem parts, will take pics of mine once out of body shop as give you an idea since our cars are almost indentical
Was the chassis okay
