I’m thinking if installing the BMR upgraded differential bolt kit on my 2018 a10 PP1 car, and I wanted to make sure the bolt kit would work with the stock rear bushings.

from what I can tell it should be fine.

I’m also thinking I may only do the rear bushings with the sleeve and upgraded bolt if the front bolts bolts are too difficult to get to. (Read where some folks have had to take the drive shaft off, etc to get to them.)

Anyone see an issue with just replacing the rear bolts and using the stock bushings?

I just put these in over the weekend. Actually, I just installed the sleeves with the factory bolts because the bolts that come with the kit were too long to fit without dropping the subframe. I don’t need the bushing inserts and didn’t want the nvh that comes with them. I just wanted the sleeves to keep things in place and keep the bolts from being damaged

How tight were the stock bolts with the sleeves, and did you have to loosen the subframe to get them in/out?

Thanks for the info.

It’s a pretty good fit with the stock bolts, although I didn’t slide the sleeves over the stock bolts to check the fit. The sleeves are a real tight fit in the bushings. I used a small rubber mallet to get them in all the way. I left the subframe fully installed when doing the sleeves. I just used a long ratchet to break them loose, then an electric impact and an 18mm swivel socket to run them out. Add a little blue loctite and tightened the bolts to 129ft-lbs.

The only “issue” I ran into was getting the bolts threaded back in. I did one at a time but loosened them both before removing either of them. I used a pry bar to move the diff so I could get the bolts lined back up. Since the diff moves because of that extra space in the bolt holes, when you put the sleeves in, the holes in the bushing and diff don’t line up perfectly. So a little persuasion from your favorite pry bar or large screw driver does the trick

Just finished up. Wasn’t bad at all.

I went ahead and used some larger (shank diameter) bolts with the spacers.

If anyone is interested the rear bolts were M14 x2.0mm 90mm long grade 10.9. I also used grade 8 1/2 inch washers.

FYI: got my bolt information from a thread started by BMR from a few years ago.

I believe the front bolts are M14 x 2.0mm 80mm long grade 10.9. I didn’t put in the fronts becuase didn’t see that being as big of an issue as the rear bolt(slop). Also my 1/2 inch washers looked a little too big for the front.
