HPF kit is better than any other kit. get theirs.

Cost depends on a lot of things. Its a GOOD idea to replace ball joints and almost anything with wear as long as you have things apart. It a good time to install adjustable rear CAMBER arms if you have coil over suspension.

If you have NA power you can stay with the stock sub frame bushings although it is a good time to RENEW them while you have everything apart. Other choices are AKG RED or BLACK poly sub frame bushings. Never use Poweflex YELLOW poly subframe bushings. They have been shown to not FIT properly and tear. Consider AKG red poly RTABS depending on your needs.

Total cost is a rock bottom of 800usd to over 2k depending on options PLUS the price of the HPF plate kit.

I have heard of group pricing cheaper than this. It so much depends on what shops are available, what part of the country you live in and so on.
My cost was 2k with all new poly sub frame bushings,all new rear ball joints and lots of additional welding beyond the normal plate install...plus the price of the HPF plate kit. I already had RTABS and rear camber arms.
You want to inspect your GUIBO and front differential mount too!

That is correct, but if you look at an installation-manual PDF for a reinforcement kit you will see what i mean can find some pics later. See also 02pruvs pictures and explanations on the last pages. Tey are very good

hello.
I drive a BMW 99, 323i. I've been lurking here occasionally . Iv been quite surprised how much you guys spend on reinforcement subframes .

Thought i will share with some photos from time i have done reinforcement.
Everything was done at garage, exept pressing in new bushings , and the price for all in total was 150$ .
The plates was not only from bottom of the car , but from inside as well(you can see the shape of the metal plate on one of the photos).
Sorry for my english, its my 3 language. .

Good job.

The one thing I'd tell you to add would be the Long bolt through design. As you can see in these pictures, the subframe bolts come through into the trunk .

Good luck,

Once the rear subframe is damaged I would get rid of the car. My e46 323i subframe cracked 3 different times. cost me a lot of money.

I just dropped my exhaust the other day to do my clutch, and noticed that my rear diff bushing is pretty much completely gone, and the left rear subframe mounting point is torn pretty good... So here we go.

Yeah, I will. I'm going to do the reinforcement kit and the cross brace, along with poly diff and subframe bushings as well.

Good.

When you say "cross brace", do you mean up in the trunk with a bolt-through design ?
Weld in or Mason Engineering ?

Weld in the trunk, like what 02PRUV posted earlier in this thread.
