Right, little update!
So on the Focus RS facebook page there had been some scary photos posted of the tin worm that plagues all fords lol, i remember giving mine a quick once over with stone chip about 4/5 years ago and it was just a little bit surface rust and nothing more. But with these new photos coming to light i thought i better have a look about, i knew the front was solid as i had been chopping and welding up there to let the 255's move about lol! So was really only the rear half of the car i was going to have a look at, and long behold i sadly found what i was looking for!
What was once a pin to hold the rear splash guards in place fell off in my hand and a little 1/2" hole appeared, dug a little deeper and it was clear ford had cut corners not fully welding up theses seams and just using seam seal lol! any way all cut out (on both rear tubs) and replaced with fresh metal!
As you can see rear tubs arnt looking the best, this was cleaned up and stone chipped sprayed about 4 years ago when i removed the rear splash guards. I blame the road miles i do in the car with all the crap thats on the roads causing this!
