Track day at Auto Club Speedway Fontana CA, Nissan Challenge, had fun with the new Quaife! So planted out of corners! Here's a short clip in the faster Red/Race group :) Sorry for the bit of glare, need to place GoPro mount in a better loc.

One issue: 280ZX brake booster gave out, but the good thing is, lets me modulate braking so much better with the firmer set up. So, need recommendations up for booster delete.

Hi Carlton,

 

The Quaife was installed then I street drove it about 50 miles easy pace as suggested, and then tracked it on one event. No noises or any overheating, all seem to work great. I noticed how nice it pulls off corners now! 

 

M Factory diff shop in CA installed it, Offset Motorwerks did the R/R, also installed a filtered breather hose to vent high in the rear deck area.

 

Do you get noises with yours?

 

This is the fluid I'm using

Glad to see you are noticing a good improvement with the LSD, I couldn't wait to get one fitted to mine as even when it was in stock form I would get some loss of power in the corners due to the inside wheel spinning, wasn't so noticeable once I had new suspension, wheels and so on fitted but would undoubtedly have still ben there if pushed hard enough.

Back posting again guys.....to update on the Quaife, it's working as it should on track, pulls hard on corner exits, no complaints on strange sounds, good so far.

But reason for posting is, coolant seems to keep getting past the cap.  I'm using the Arizona Z Car cross flow alum, and have used 13, 16, 20 lb caps, still not solving the problem. Pulled the plugs, looks good with brownish insulators, no oil burning. Although I haven't done any leakdown test, could this be a head gasket issue?  It seems street driving doesn't give the same issues.  Any ideas?

So bad!! Photobucket really messed up my earlier build progress pics hosting. Anyway here are a few. 

For comparison performance wise, at Auto Club Speedway in Fontana CA, on the 2.7 mile Roval (front straight, banking, and infield) best time is 2 min flat, versus my previous E46 M3 which ran 1:55 with about 40 whp more.
