My ex has a 2003 R53 MCS she bought new (and still has). As some of you know, these cars are prone to strut tower mushrooming - thin upper strut mount sheet metal and thin chassis sheet metal combined with harsh northeast potholes mean this is a chronic issue. When she first learned of this, we took the car down to Helix (MINI specialist shop) in Philly where the owner pulled the struts out, straightened the mounts in a vise and pounded the chassis metal flat again with a block and hammer. Having done this dozens of times, he did this was us watching and B.S.ing about life, MINI's and various things automotive. We were probably there a couple of hours and I think he charged her $50.
How to prevent the mushrooming? Well, today there are a few ways, but at the time, a MINI aftermarket company M7 was selling "tower reinforcement" plates - essentially, a strut brace without the cross brace. She bought a set and I installed them.
Fast forward a few months. Now due to reasons beyond explanation, she hates M7 and it bugged her to have M7 parts on her car, so when another company Craven offered their own version (Strut Tower Defenders) she bought them.
A week or so later, the new plates arrive. It's a Tuesday night. Swapping them out should be easy. Don't even need to jack up the car - just open the bonnet, remove the three nuts on each side and swap the plates. Should be an easy 15 min job.
I remove the nuts on the passenger side - and the plate won't come off. WTF? The strut mount mushroomed. Again. WITH the M7 reinforcement plate. Both sides.
Sonofa...
So at 7:30 on a Tuesday night, I jack up the front of the car (this is before I bought the lift) and proceed to pull the struts out of the car to make everything flat again before installing the Craven plates.
Around 9pm as I'm closing everything up and lowering the car, it hit me - I had just torn the front suspension of my g/f's car apart - the car she needs to get to work the next day - without even giving a thought to the idea I wouldn't get it back together in time. I just did it.
While I readily admit I still have much to learn about wrenching on cars, I definitely moved to different level that night.
