How long did the install take you if you don't mind me asking? I am mechanically inclined and wanting to do the vince bar as a preventative measure, but don't want to be out a car for the spring weather!

Yes, it is very minimal. Quite happy about that.
The separation is the first thing people should check. You just have to remove the wheel to see if there is any. Quite easy.
I made this thread just to remind people to take care of that issue.

I can't really tell because we did a lot of stuff at the same time.
If I had to guess, and you are committed, you could do in 20 hours of work.
But take that with a grain of salt.

I love the garage walls...are you in the basement of a medieval castle or something?

Haha. No, I don't live in a castle, but in a really old french house that we completely renovated in a very small village (less than 300 people living here).
The walls are really thick, about 80 cm (31 - 32 inches).

very similar to my seperation. i ended up swapping the entire floor out for a new one and went with vince front mounts and mason X brace while i was at it.

I would change the entire floor, don't waste your time money and effort in fixing this.

For those small cracks ? No way ! You really changed the whole floor?

I think that is overkill.

not for the small cracks but the wheel well seperation. look for popped spot welds all around the wheel wells, spring perch area and around the spare tire area. You probably have a few. then look inside the trunk to see if the floor is separating and has dropped. my guess is that you haven't inspected the entire floor carefully, once you do you will realize the damage is way more extensive than just a few cracks here and there. at least that is what i noticed after tons of searching around.

His might not be that bad yet, but I'd definitely inspect the tops of the front mounts and reinforce those welds if I were him. Yours had cracks around the spring perch if I remember right. He might not have that yet, but I agree he likely has other spot weld stress in the floor next to the wheel arch.

Some general advice for everyone. Buy and use crack locating dye. I thought my front left was ok, but just happened to see a crack in the right light. The cracks can be longer than you see with your eyes as well.
