Its a rear anti-roll bar for a late 1973 through 1978 S30. You car does not have the factory mounts on the rear frame in front of the tires.
-
I just take a hammer and bend the frame rail lip up.
-
Generally a sign of poor valve train assembly.

Its just the crap that Megan is. Regardless of whether they "made" them for the S30 or not, they are crap shocks.
-
Bad idea.

You do not need the finned cover. Your diff will not overheat. The only issue you might have is the ring gear bolts. The earlier R200s used 10mm ring gear bolts and the later ones used 12mm ring gear bolts. If you search you should be able to find the transition year.

I used to run a hitch on my 240Z. It was custom made and I used to ahve pics somewhere but I can't find them now. I'll try to describe it:
1. A large tab is welded to the center of rear transverse link brace with a hole for a 3/4" bolt.2. A flat piece of steel, 1/4" thick by 2" wide is bent to go from the tab to behind the rear bumper (centered) closely following the contour of the fuel tank and rear valance.
3. Behind the rear bumper and between the body of the bumper is a square tube (1 1/4" x .083" wall) that spans and is bolted to the stock rear bumper mounts. You will need to weld tabs to this square tube to match up with the bumper mounts.
4. The flat steel piece in #2 is welded to this square tube and bolted to the tab on the rear transverse link brace with a 3/4" grade 8 bolt..
5. A hitch tongue is welded to the junction of the flat steel piece and square tube extending out behind the bumper.

I only want those ratios, no 3:54s, no 3.90s, etc.
No thanks.

How deeply do you probe?
As deep as I can. I really try to bottom out, but that's just a dream I have.

Nissan Motorsports is NLA on all new ring and pinions - at least they were out two years ago.
-
Oval the two holes in the strut tower.
-
No thanks. This is for a race car and the R230 is way too heavy.
-
Search the site or do some Google searching. The shock itself is inconsistent, cross bleeds, and no two shocks are the same regarding the valving.

I'm the web site programmer and I do a crappy job. A R200 is a R200 (mostly) so yes, the same OSG unit works in all the long nose R200s. For the ones with the 10mm ring gear bolts I also sell hard bronze bushing that take up the difference between the bolts and the 13mm drilled holes in the OSG diff flange.

I've seen someone machine the Toyota S12W caliper to look like the MK63 caliper. It was good enough to get the car through European FIA Historic racign tech inspection.

Here's an example of the tunability of the OSG diff. One of my customers autocrossed a E36 BMW in FP and won a national championship in that class, beating John Thomas' 240Z. The BMW had an issue in long slaloms where it would develop a sligh push when getting back on the gas betwwen cones. The push came on about halfway through the slalom run. Taking with the OSG folks we determined that the quick on-off-on throttle through the slalom was pumping the diff oil out from between the clutches causing a slightly harsh lockup. We repalced the flat clutches with clutches that has oil grooves machined in them and we adjusted the lock timing so that the clutches would start to lock up sooner. This solved the push problem and lead to a national championship.
-
I'm biased. OS Giken Super Lock. I've sold units to street, road racers, and drag racers and every customer is very happy with the results.
-
IMHO... anything that shuts off the engine based on oil pressure, temps, etc. can be a very bad thing. Think driving at the limit in turn 9 at Willow Springs and havning the engine shut off and lock the rear wheels. You will be dealing with far more damage to your car and possibly yourself then just some spun bearings.
A big yellow idiot light is a better idea.
-
For a street driven car the rear rotors don't matter much. You'll never get them hot enough to worry about craking, warping, etc.
-
S12W is the only caliper of that family that fits vented rotors.
-
Yes, all the parts are still available.

All the parts are available through a good diff shop.

Depending on how low your car is, adding spacers might create a bind in the end links. But they also give you more clearance at the oil pump.
