Yeah, forgot to mention that. The spacer accounts for the thickness of one additional clutch/wear plate, and you machine for the 2nd.

Hard to tell, I only have Continental ST slicks for the car right now, and it was 45 degree with no sun. Never got them even remotely warm so I had zero grip and no confidence. I was also really disappointed with my driving after watching the video, I haven't done much autocrossing in the last two years. The car was not pushy though, which is what I was worried about with the diff. I also think the 3.23 is too tall, I was barely getting over the stock rev limiter
Here is a video

Nah man still looked pretty good. Don't get down over the first event with a new set up especially with those conditions and those tires. Reviewing video always makes it seem slower. The right tire is going to make a world of difference. I really wish i hadn't seen that video. Car sounds mean as hell and now i want s54 power.
How are you liking that brake set up aside from being boosterless?Last edited by tinkerputzer; 12-09-2014, 08:47 AM.

That looked FAST! Where I've ran we don't go that fast I don't think, Maybe the GT3s do but my m42 doesn't go that fast!
I keep going back and forth on LS vs s54 as my dream swap! THAT NOISE!!!-Christian

The car was fast, but I was not. I was very familiar and comfortable with the car in it's previous configuration and I definitely do not have that feeling anymore. I was not able to get back to gas and carry and speed anywhere. Just need more seat time
The brakes are ok, still not confidence inspiring but they were better than I thought they would be. Especially for not being warm and having stock pads in the rear. I still need to make some bias changes when I get race pads in the back and mess with the pedal adjustment a little bit.
One thing that was very obvious in the video is I need a steering rack. The corrections that seem minor and don't really register as they are happening are pretty big on video. What is the best option on a rebuilt z3 1.9 rack? I can't see myself spending $500 on one from Rack Doctor, anyone have any suggestions?
Lorin, what diff is it? I have this thing all set up with the 4 clutch now, so it would be a PITA to change gears again. I might just try to work with this for a while. Hopefully with a remote tune from TTFS I can smooth out the power delivery, it's pretty peaky right now- '88 m54 coupe

You can grab a new z3 1.9 rack from a company called aae. New, so no core needed which is nice. Mine is certainly quick. Approx 2.7 turns lock to lock just as advertised.
They only thing is mine felt to light at speed and super heavy when I was still. An alignment and tightening the preload on the rack fixed it. Rockauto used to carry them but not anymore.Euro S50 Daily Driver: http://www.r3vlimited.com/board/showthread.php?t=279195

It's a stock LSD out of a 7 series with like 90k on it. I want to keep the diff, but you are welcome to borrow it to see if it is the ratio you would like to run.
Honestly, it sounds like you made so many changes to the car that it would probably be best to get used to all the new aspects with seat time first. What feels like the wrong ratio now might feel great in a few months.

I didn't go with this one because i found it after the fact. May want to verify it's 2.7LTL.
