Steve, were you able to fit this PN: 38335-N3220 to the pinion of the R200?

So I've been playing with the installation of a OBX in my R200 for several weeks now and have gone through just about every scenario regarding upgrade and fitment. One thing I seem to have overlooked was the tolerance of the press in splined side flanges to the lsd machined splines.....and guess what.....my drivers side fits nice and tight, not so much for the pass side. I'm getting rotational play, no in and out, I've replaced the circlips with new ones. Checking the side flange tolerance back in the original open carrier it fits nice and snug like a factory fit should. So now.....what to do? OBX Racing Sports doesn't respond to manufacturing defects or tolerance issues and won't guarantee against them especially after the unit has been modified and installed. Can anyone think of some long term/heavy duty solution to decreasing this play? I'm measuring about 0.020" of "backlash" between the teeth.

PMd you.

Just peek into the front wheel well with a flash light when you have a chance and report back if you can, I'm interested in knowing if it looks like the photos I posted above. Thanks

Considering you have a 280, do you have the coil binding as I do in the front?

Interested in knowing if you installed them as VA in the front and the HA in the rear?

Going to bump "stop" this nearly a year later with my results having recently installed them on a 240Z. As one can see, the set is two different designed springs, not the similar looking ones used on the 280s. I installed the VA in the front and the HA in the rear (not entirely certain this is correctly labeled by whomever manufactured them) as specified by previous posts. On the ground the Z looks level and has even gap front/rear and rides very well, not jarring, not bumpy, smooth and quite comfortable. The measured drop from oem springs to these is approximately 1.6" in the front and .75" in the rear with the drivers side being 0.125" higher than the passenger side to accommodate drivers weight. The one area of concern is with the front coils being near coil binded throughout the entire length, which makes for only an inch or slightly more (not actually measured) of actual travel...I was wishing for more as I don't need to be this low. I understand its due to the design of a progressive spring including coil bind as a "helper" but why even design a spring to be this compressed with such a short travel? With the sheer lack of info on the manufacturing run of these through Vogtland and the added lack of info from any vendor which sold these I'm really wondering if the springs need to be swapped front to rear as similarly reported over the years with users of Eibach getting all confused as the F/R stampings changed from Eibach to MSA through their change-over. I haven't measured the actual spring rates of these other than accepting the data originally posted by JohnC (The 240z rates are 152 fronts and 170 rears), but I'm wondering how the balance and handling will be affected by the swap if done??? It's too bad there are such few options remaining for Z lowering springs on the market today. With most going the coilover route I can see why, but for those who don't want to go that route it's tough to find a well balanced solution. Vogtland Kit: Vogtland Front w/vehicle weight: Vogtland Rear w/vehicle weight: Another discontinued lowering spring option was Tokico, very similar results to above.

Bumping this ol bugger.......can someone clarify which terminal slot 3 wire connects to on the coil? 3) Insert new pin into slot 3 of ECU connector then connect to a new wire going to the _______ terminal of your coil. The car seems to run OK without this step, but I still wired it since it was done on the 300zx. I have a MSD and the car is doing well with it
