I am planning on doing the mods below guys:

- M diff and half shafts ( they are ****ed. Very lose and causing a thud noise )

- M calipers and spindles

My question to Charlie or anyone else is

1. If I change the spindles I will have no problem fitting on M calipers right?? and will it fit within a 16" wheel.

2. I want to change my diff to an LSD 3:15, 3:23 or 3:38. If I where to change the diff would I have to change the half shafts as well ?? Is the housing bigger on the M diff. I need to replace my half shafts anyways so I plan on doing it all.

Thanks guys

I'm not Charlie, but I'll give it a try.

I have a M spindles and calipers to install. Once you get spindles, the calipers bolt on no problem. Regarding 16" wheels, I don't think the caliper will clear the stock 16" sport rim. I can check it for you sometime though.

Regarding the diff, the 328 and M3 diffs are basically the same (externally). The only thing you have to watch out for is the number of bolts on the input shaft (driveshaft). There are 4 and 6 bolt flanges. If your current is 4 bolt and you get a diff with a 6 bolt flange, you can just pull the flanges off the diffs and swap them. I have an M3 3.15 diff on my car by the way.

Awesome pal thank you for your input no matter if your Charlie or not. I don't think the calipers will clear my rims though. I am worried about the winter rims mostly. As for the diff I think it should give me big time acceleration ?? Did you notice a big acceleration difference Thinair

thanks again

Mkgino and I did a second gear pull at Bimmercruise. We went from idle in second gear to redline. I had a car length on him, maybe a little more. You'll have to ask him, he was behind so he had a better view of how far ahead I was. :moon:

We both have 97 328is', he has an intake, exhaust, and fan delete, I had an exhaust, debaffled airbox (at the time), 3.15 diff, and the fan delete.

When it gets warmer (like not -20ÂșC) I'll go into the garage and pull out the 16" spare I have and bolt it up to the spindle I have (with the rotor and caliper bolted on too. I'll let you know if it fits.

I noticed some with my 3:15 rear end. It will help for sure it revs a little bit quicker. If I were you though I would opt for the 3:23 or the 3:38. The 3:15 is good but now I find myself wanting the 3:23 or the 3:38. Hope this helps a little bit. Cheers

Me too, I actually found a 3.38, but I just didn't want to part with $1200 at the time. I wish I had the spare cash, I would've sold my 3.15 so fast and paid the difference for the 3.38. I don't really want to get a diff until I can afford both the diff and a finned diff cover.

By the way, appearently a stock 328 with a diff 3.46 will keep up with a stock M3, until like about 200km/h or so.

The limited slip alone makes it worth it though. I couldn't imagine running an open diff in auto-x. When I raced my truck I had one wheel peels around every corner, and that thing is only like 90 hp.

Well this guy has a 3:23 and it is LSD so I am excited to see how well it will work guys. Thinair if you could find out if the wheel will fit with the M calipers that would be great. Please let me know.

Thanks

3.23 or 3.38 ... I want either. *mw* You can also get a custom one, I think Quaiffe makes them. GR8RIDE has a custom one, I think 3.46 not sure by whom though.

Have you contacted VP M3 yet for the brakes, he may have the shafts still. I think he's parting out a '97 M3.
