That seam needs to be grinded off. Have to get a shop to do that since I don't have grinder nor planning to run a grinder 5 inches away from my face.

Also, it seems like my diff sits a bit higher than the brace was designed. If the top of the brace has to sit flush against the subframe, the opening for attaching the diff cover is about 1/4 lower than it needs to be. Played around with aligning the thing, but can't seem to figure it out. Not sure how you guys did it or it is just my car.
Thanks for the feedback. If you wouldn't mind, could you email me some pics? Email is BoostAddictions@gmail.com. Getting the wholes lined up can be a bit tricky, but they do line up provided there isn't something in the way as you described.

OK so I got it in yesterday and then installed it last night.

lets start with the product. The part looks great, welds were on point coating was all even. The bolts he sends you look very strong. I give it a 10/10


now idk if this is a 135 problem or maybe this is isolated case for me but this was a huge pain to put on. Very simple in theory however I could not get the holes to line up good for me even with applying pressure. The bolt holes on the bracket were slightly to low to match up to the diff holes. I drilled the holes out maybe 1mm and it was enough to get it to fit with some muscling in. I tried everything to not have to drill it but it would not work so I did what I had to do. Overall its an easy job just took a long time to get it in good.

I took it on the road last night and initially I though it wasn't doing much. I still had wheel hop but then I realized that was just ****ty nyc street but I managed to get on a quite concrete highway and took off in first gear. I noticed rite away no hop and the car stayed straighter. The car normaly kicks out all over the place but it went great. I strongly recommend the product and for us 135 guys you may need to mess with it abit to get it good but its well worth it.

THANKS A BUNCH

I really want this on my 1er.

I'm just concerned because I feel like it's such a hit or miss on the fitment.

Not saying anything bad about the manufacturing part of it, the piece looks great. It's just that every car is so different from the other even if it's a slight differece.

I know some people's braces weren't too far off but there is a chance of that as well.

As you can see from the first picture how off the hole is however if you apply enough force you can move it almost to the rite position. Another thing I could of done was put a jack under the bracket to push it up abit more then maybe iwouldnt need to drill it.

That doesn't look bad at all.

two questions. Because the bracket is kinda off, does that force the diff to be in any position other than the way it should be?

How are the bolts on the diff? is that going to create too much stress on the bolts and cause them to kinda wear out prematurely?

Oh and I don't know if the diff cap is any different but I have the M Factory LSD in my car.

good questions. The diff is stronger then the bracket. Your forcing the bracket to fit. once it is bolted in that's how it will stay. I though the same thing about the bolts but the bolts are strong I don't think there should be any damage to them. Im planning to recheck all my work after a few days and make sure everything is still good.

That makes sense. Thanks.

Here is a pic of what my diff looks like.

I should be all set. I really want to order this thing.

Thanks for the review and picsgoldfz8.

This is why I said it can be tricky to get the bolts started. If you just hold it up everything looks totally off, that's normal. As you get the bolts in everything just sets into place. I may make the holes one size larger on the next batch to make the install easier. The reason it is like this is because there is no adjustability in the unit, so it will take some force.

The tight holes are actually better for the bolts. That's one of the reasons I kept them on the smaller side. With a larger hole there could be some movement which would actually stress the bolt more.

Bostonshant, your car should still be a large diff car so it shouldn't be a problem as long as the cover is the same. Post a pic. Also reference the holes in the first post as well if you can.

Edit: I'm a slow poster lol. The cover appears to be the same, and the holes look to be correct as well.

I completely agree that the holes should be small anyone who is installing this should have the tools necessary to make them bigger if need be. this product should of been on the car from factory LOVE IT

Awesome!!

Just placed my order. Can't wait to get it in.

I will follow up after I drive it for a few days once I install it.

It you just start both bolt without tightening the ones on the diff the brace will slid righ into place. It's easier to start with the passenger side bolt first. This unit should then fit perfect. Had zero install issues what so ever. And my holes were a bit smaller due to the fact I'm using the original/prototype one ever made!

lol I tried every which way I could and it was not happening. top bolts first then bottom, bottom then top left to right right to left.

Ok, mine is off a little more than goldfz8. But I think it is because the aftermarket subframe bushings that are on my car, since they sit just a bit taller than the OEM ones, therefore dropping the subframe a bit lower than it was before. Together with the very significant casting seam on my final drive housing, it just makes it much harder to get everything aligned. Will try to get the shop to install later this week instead.

Aftermarket subframe bushings should have no effect on brace fitment cause the differential pumpkin is held together already with subframe by the big (main) rear differential bushing. I need this badly on my car. Even with race stiff 95a poly Powerflex subframe and differential bushings paired with MF lsd the rear end is still all over the place. Handful under any harder acceleration.
Btw. Are the braces still in stock ??? And when the second batch will be ready ???

am I missing the obvious here? How to you tighten the connection at the subframe? can you get a socket in the frame?

I have 1 left in stock. Also no guarantees on fitment for the small diff yet. I'm gonna try to get my fab guy to start working on another batch this week. No ETA on those yet.

These type of lock washers make it so you don't need to get a wrench on the top bolt. You can fit a wrench in there should you need to.

Thanks.
Looks like the fitment for small pumpkin might need improvement. How about making 2 different options for small and big ??? It would make sense as they are different in size.
