I wouldn't go to the full locking plates but the 250 ft lbs one would be nice.
If the clutch plates are really around $200 at dealer, it might be nice to use new plates and their kit and have a decent locking diff for around $300.

It might be nice..........................


to look at the plates before hand.
Betcha a nickle right now they're fine. Come on a whole nickle!
and yeah get the 250 ft/lbs ones.
Swedes FWD guys told me with PS, they go 175 ft/lbs, and more for Right Wheel drive..

I've heard them clunk at 250 ft/lbs on hard packed dirt when my man was dancing the car.. wouldn't think they'd ever slip, but they did differentiate..

So how difficult is setting a diff up? Doable in an afternoon?

Cool, so sounds like the middle kit might be a good use of $75...and then when I take the diff apart, I'll check to see if I need to drop $200 on new plates from the dealer.

John - do you remember the specs to which that 4.56 diff was built to?

Dave

Order me one also when you place your order. We can do them together for fun and learn together. We'll move my nice workbench to the middle of the new shop and work opposite each other. Film the whole thing. Nothing else in the shop. Funny.

Waiting for the guy to email me back with a quote for doing a rebuild...so depending on how cheap or expensive that is, I'll make the call as to if I try doing it myself.

Dave

rebuilding the center section should have no effect on gear contact and pinion and carrier bearing set up. I forget, do they have threaded bearing cups on the carrier or are they shimmed? either way, you can disasemble/reasemble without need to set up the ring and pinion.

Yeah I need to re-fresh my pea-brain what we finally ended up with on front and rear on yer Bavarian Macho Weenie-extender since I just got 2 orders for suspenders.

Shocks - valving as orig. supplied
Front Springs as orig. supplied
Rear Springs - Hypercoil 200# (14"?), had more travel before coil bind than the orig. springs
Rear Bumpstops - replaced with a 3" one. Fairly certain its this one.

The infection is spreading evidently.

Excellent! Now if I could just find the time to get mine finished and out to a rally. Testing at CORE is one thing...confirmation that it rocks at a rally is even better.

Had a chance to get the BMW out for the season opener for the Colorado Rally-X group. I drove the Evo but let Grant (he of the unending merkweird project) and Josh (maker of cool videos) wheel the BMW around the course. At the end of the day those bastards had the car loaded up and strapped down before I came back from my last run so I didn't even have a chance to drive the BMW at all. All in all though it was a good day as we drove both cars back onto the trailers at the end of the day.

More of a writeup here, along with a few pics and links to videos:

Or if you just want to see the video, here ya go:

so there are a lot of pages floating in here. What transmission did you use with this?

Stock trans that comes with the M3. I think it's a ZF.

Dave

excellent. Basically, Im assessing my options for rally car 3.0 since the rx7 is small as heck and somewhat death trappy. I know of an E36 M3 i can get my hands on with an engine issue for about 800 bucks. Its very tempting to go with the BMW route. But the parts costs concern me. The supra differential idea looks excellent, but its seems as though it has taken you plenty of time to figure out the suspension aspects.

A real 4 cylinder 16v E36? The good one?
And you're not selling blood and walking the strip with a sign-board saying "Say Airman, looking for a good time?"

EVERYTHING can be fixed in motors and it all costs about the same..

Or is that the E30 M3 I'm thinking about?

JV that's an E30 with the 4banger. I know you say the 6 has a floppy crank, but it seems you could run one basically stock and unstressed and make tons of torques?

yea the E30 has the four cylinder one. This would have the 6 cylinder.

To join in the lastest trend: what the fuck do I know?
All I know is I've never seen a decent handling on gravel inline 6 car here.
