From the album: 1980 Maxima vs 280zx rear control arms under the Strutless Wonder
Compared to the Maxima setup on my car, this 4 bolt halfshaft flange has a much shallower recess, as you can easily see the stub axle bolt here. The flange is about 3/8" shorter than my Maxima setup. -

An early 280zx rear control arm, but note the single thick disc brake mounts flange welded directly to control arm and 4 bolt halfshaft flange isn't as deep as the Maxima setup I've been running on my car. It appears the two setups are NOT exactly interchangeable, though they use the same brake disc and caliper, same control arm bushings and 1/2 shafts. Shock mount stud is also angled just a tad differently. Who knew? -

Note 4 bolt halfshaft flange is deeply recessed so you can barely see stub nut. -

Note thick flange welded directly to control arm. 2nd thick flange bolts to 1st flange w/ 4 bolts. 2nd thick flange has 2 threaded tabs ~3.75" c-to-c that allow OEM early 280ZX rear disc brake caliper to mount. Note 4 bolt halfshaft flange width is longer than flange on 280zx. -

I was told these were 1980 280zx rear control arms, but the bolt on disc brake bracket and deeper 4 bolt flange didn't match a 2nd pr of 280zx arms. Uses same disc and brake caliper setup as 280zx. These have been re-drilled to 5x4.5" spacing. Uses OEM solid 10.6" disc that has also been re-drilled to 5 lug. Brake disc weighs 10.25lbs each, brake caliper & pads weigh 8.66lbs each, and bare control arm w/ hub, 5 lugs and poly bushings weighs in at 30.25lbs each. -

All one piece 6061 aluminum, CNC'd from a single piece. Eric Straw did a fantastic job of getting these made. Stock steel moustache bar w/ bushings weighs 4.18lbs. This aluminum bar w/ bushings weighs 2.22lbs. Uses TMC part # CIN-245 240z polyurethane bushings which are a tight press fit. Too bad the spare tire well blocks it from view unless the car is up on a lift. -
You could file away some of the bolt head for clearance...

Or use AN10 bolts which have a slightly thinner bolt head height. Or get new brackets made. Or use AN10 blts and new brackets, just to be safe. Interestingly, the stock 510 control arm pivots are just a bit smaller outside diameter than the 280zx control arms and don't interfere with the mounting bolts. -
Rear control arm 5/8" bolt head interferes with control arm

Had to get a set of version 2 brackets made with pivot hole moved 5mm further out. Although control arm in this picture has polyurthane/steel bushings, these have loads of "stiction" and will be replaced with Design Products Racing spherical heim jointed inserts and 5/8" bolts (to replace the OEM 12mm bolts). -

Rear crossmember uses TMC part # CIN-247 polyurethane bushings in place of OEM metal/rubber units. -

Had to have a second set of brackets (on L) made with control arm pivot moved 5mm further outward to prevent binding w/ mounting bolt -

Jeff Klein did a fantastic job turning a stock Datsun 510 rear crossmember into a massively reinforced custom piece for my car. The outer control arm mounting points were reinforced front and rear with large steel plates. The spot-welded trailing edge "lips" were seam welded. Rear sway bar bushing mounting plates were welded onto the bottom. Exhaust hole was enlarged to 4" for my 3" exhaust. Custom spacing allows me to use 280ZX rear control arms with custom brackets and 5/8" control arm bolts with Design Products Racing heim-jointed bearings instead of the "sticky" poly bushings. -

Not sure how this happened. Didn't see during a very thorough pre-track day inspection 2/2010. Didn't hit anything or go off track at the HPDE at Laguna Seca. I'm VERY glad I found the carnage before it found me at speed.
