Got some projects taken care of yesterday and this morning. Started with some brakes:
I stole an idea from a Volvo forum...stacked sway bars. I came up with a total of 3 stock sway bars. One was on the car, one from a B210 I parted out years ago, and one from a guy I know. The 510 and B210 bars are almost identical. Maybe they are actually the same part but I found the 510 bar was just slightly wider -- maybe 1/4". It goes something like this. Started with this pile of parts:
Painted the sway bars. I had to make one of the U shaped brackets too, (2) 1/8" rectangle shaped plates. (4) 2.5" bolts, (4) 1.25" tube sleeves, stock end links + 2 extra bushings to go between the bar ends.
The next few pics are pretty self explanatory:
After I got it on the ground and drove it around the driveway a bit I discovered that the lower bar would contact the TC rod on hard bumps. I ground the offending area a little (probably 1/8") and all is well. If my car wasn't lowered it may not have been an issue.
I also experimented with my stash of random sway bars to see what I could make work of the back. Guess what? A stock 510 front bar fits pretty well.
The center mounts were just 2 1/2" exhaust clamps and some 1/4" plate.
The end link mounts were some 2" angle iron with a gusset welded on the back side. (The rearend is at full droop in the photo. At ride height it is pretty much level.)
There is no less than 1/4" clearance at any point. My car has 2" lowering blocks on the rear. I don't know if this would work with a 1" block and I doubt it would have room at all with stock rear suspension. I haven't had a chance to punish it through any good twisties yet but just driving around town it feels dramatically better. In theory this should be a pretty good balance. The same amount of torsional resistance was added to each end of the car. I'll update once I give it some serious drive time.
Last part of the upgrades were some borrowed AutoBahns from my brother's lonnnnnnnng term 240z project. I had to buy my own 195/50-15 Falkens since his tires were too big.
