Looks like I am going to have fun with those mounting brackets as well

How are you going to shorten your bumper shocks? cut and re-weld? back into a wall? lol....

Lol dude no way. I didn't want to say it but my passenger t50 bolt seized on me as well and ended up stripping. I actually removed the bumper cover by taking out all the push clips haha. Gonna have a shop get that bolt out for me tomorrow as well lol.

Yeah I'm gonna have the exhaust shop cut and reweld. Safer that way. Too many negative variables that can happen with backing into a wall lol.

I didn't, ..... look at the pics again. The top part of that bolt sheared off when I was unscrewing it.... It actually broke off like that and the top part of the bolt that broke off is still in the top part of the reinforcement bar.

Haha ouch! Yeah my bolt is stuck in the reo bar as well fml lol, at least yours broke!

good luck today

This is how the wheel, fender, and fender liner look with the wheel on:


Wheel well:


I cut the fender liner with a dremel. This I what it looks like now:


I totally removed the metal fender clip and screw. I shaved the screw off with a dremel and then used a self-tapping screw from the bumper cover to the body. The bumper cover will actually be pulled in enough to where you don't need the self-tapping screw, but I did it just to make sure nothing moves. :



This is a close up of the outside. You can see that the screw I used to mount the bumper cover to the body it is not visible.


I hope these pictures help.

btw the reason why I removed the screws and clips on the sides was because I have low offset wheels with 255s on them. If your offsets aren't too aggressive then you don't have to do that.

A link for the piping (Not my car) but its all the same:

Awesome bro that helps me out a ton! I've been working on it today a little bit. I have some pics that I'll post up later too

Not a lot of progress today. Unfortunately that broken bolt in the reinforcement bar caused some problems. I did test fit the bumper and then shaved the brackets. That's about it.

yeah same here bro, took me 4 hours to get the bolt out of the reo bar. But i finally did it, after about a dozen broken dremel attachments a couple bent drill bits and a few broken flat heads haha. I did some damage to my tools trying to get that sucker out. I ended up just drilling it out, and somehow managed to keep some threads on the end

I did get one side finished, the passenger side. And that happened about 30 minutes ago haha. Ill finish it up tommorow. Im definitly going to need to shorten the bumper shocks as the bumper is 1.25 inches short

Ill post some better pics




Heres one of my feeble attempts to get that bolt out. Made it a flat head and attached a bit to my socket, the bit ended up braking haha.


And here's to show you that on a sedan not only do u need to modify the brackets. You need to shave down the metal flat right in front as well. IT WILL GET IN THE WAY and cause a nasty gap

subscribed for later research

so you used the original mounting points for the brackets?

id love to get the m3 rear bumper but with headers and no cats and the 2nd resonator removed my car will wake the dead if i take the muffler off to route the exhaust to line up...its as loud as an m3 right now with the stock muffler and sounds like one too. ill just wait until i have the s54 in here to put the m3 rear on.

No those were pics to show people what the original bracket looks like and the metal flap in front that needs to be shaved down. I'm goin to start working on it again now. Here's my pics of the fitment. It pokes a little but I wanted it that way so when I shorten my bumper shocks it will sit completely flush.

nice progress.

wow, that looks really good. When I mounted the brackets to the original screws and mounting points, my bumper sat out about an inch from the body. I will need to shave the screws off from the body and remount the brack closer in to the body. Then push the bumper shocks in. I heard an inch is good. I know you measured about an 1.25" short. Let me know how that works out.
