Do it while it's apart. Use a wire wheel to really clean the seam. You can't weld sealer.

Good grief

So it looks like its just tearing/peeling the steel rather then lifting the spot welds? Its hard to see whats going on there. But if its tearing the steel, how is welding going to achieve anything but just have it tear around the new welds later?

How much shit do I need to remove to have this done? Seems to be a bit of a logistical issue with sending the car to the shop to do. Might need to find a competent mobile welder after dismantling my own car and he can come to my house wile my car is on jack stands. Hoping can just remove the coilovers and leave the control arms in place?

its breaking the spot welds. i welded mine myself with a 70$ flux core wire welder from HF, do as rob suggest and clean it with a wire wheel then drop some welds. mine shitty welds havent failed using rcomps for the past 2 seasons

sell ap1 --> buy ap2

LOL. JK.

More seriously, it depends on how long you plan to keep the car and how many track/auto-x events you plan on doing each year. If it's a 3-4x a year thing and you dont see owning the car for more than another 3-4 years, then don't bother. If you're in it for the long run, it will eventually turn into a failure point. I'm of the mind set of addressing known failure points ahead of time.

But, i think differently. I bought and installed a BBK two years before getting coilovers. From a long run standpoint, it made the most sense at the time and has proven to be the case.

Same here. Tore mine on RS3s last year after 3 years of heavy track use on street tires only. Had a shop clean/weld it up and it's good as new.

Well it happened, I guess I finally learned how to brake hard and upped my cornering. XP10/8 with RS3s.

I heard a crunching when turning the wheel at low speeds. At first I was unsure what was going on but after some thought, I knew what to look for. Sure enough my A arm mounts are pulling away.

It is advisable / necessary to remove the ECU when welding on the car?
