I'd recommend an alignment after this. Something will be out of whack after you do this.

Did this last night, cost me 15, but thats because of the area I'm in. used 8.8 bolts, only issue I had was no matter what I did the drivers side hole would only let the bolt thread in, the bushing didnt fit, even after loosening the subframe mounts. I ended up just grinding ~2 mils off one side of the hole, still a snug fit, and it actually git rid of a lot of the noise that came from the rear of the car. Seems worth it imo, will see how it effects handling today, but I'm not expecting much because I already have a rpm front subframe.

Ok, sorry guys, i fixed the original thread now.

It now specifies what grade bolts to use, and also has step by step instructions of the install ***Including cleaning the threads out first***

I've already got the Kartboy rear subframe bushings installed, is this mod still worth doing?

it wont make as much of a difference, but it should still keep the rear sub frame a little bit tighter.

Still have to bolts in my car, and still no problems(about 2 months DDed with lots of spirited driving). i love the way the rear end feels now.

I also installed these on a friend's car, and they went in great and work great on his car also.

So I have about 30,000 miles on the bolts now, and they still work perfectly. I checked them the other day to make sure they are tight, and they are fine. Working on building my stroker motor now, so these will be getting plenty of stress in the future also.

Thanks for the update I will diffidently be doing this I am about to cut my whole trunk out lol cause all my bolts for my sub frame in general have snapped nuts in there. How did this affect handling and where did you get the brass 3/4" OD x 1/2" ID Bronze Flange Bearing.

I got mine from my local ace hardware. But as I posted before, mcmaster.com has them, and most hardware stores can order them if they don't stock them.

If you live in SoCal, McFadden-Dale hardware has the best prices for fasteners that I've seen.
