    Hawk DTC70 and DTC60 are pretty good too. Been running them on my 350Z. I actually just bought a set of the Raybestos 43s and 41s as the next race pad set to try. Porterfield Brake custom cuts the pads to fit my calipers.

    If you're only lowering the car 1", don't worry about cutting the bump stops.

    Depending on how low your car is, you might want to trim the ES bump stops. They are 1.750" long. Trim them so you have at least 2" of shock bump travel at your ride height before the bump stop hits the gland nut. Trim a little from each end of the bump stop, not all from one end.

    Buy Nissan OEM ball joints. Yeah, they are stupid expensive but I've compared a number of lower priced units and they all have different installed heights, even two from the same parts store.

    Tokico ships three parts witht he Tokico Illuminas: Gland nut (use the one they supply) Lock nut Gland nut shim (this should take up the slack in your install) Tokico does not supply bump stops, you should re-use the stock ones, unless they've rotted away or were tossed in a previous shock repalcement.

    Hubs go out of round and spindles wear from track use. I the past I've replaced hubs every couple years. When you install new races, everything seems fine until they hub is used under load. Then the race distorts a little bit to match the hub, clearances open up, and now you have some play you can't get rid of.

    To weld a diff: 1. Clean, clean, clean, clean, and then clean some more. 2. Put two side axles in the diff and apply a little force in opposite directions on each to take up any slack. 3. Turn up the heat and wire feed and tack weld the spider gears to the side gears. 4. Remove the side axles. 5. Finish welding using a lot of filler wire trying to get good penetration and an even buildup of material. You don't want to unbalance the diff by having a lot more weld in one area. 6. Let it air cool and then wire brush everything. 7. Put the diff back in the housing.

    If you can find a new stub axle, buy it! They have been NLA from Nissan since the late 1990s. I was able to purchase the last two 280Z stub axles that Courtesy Nissan was able to find back in 1999. If the stub axle breaks right under the stub axle retaining nut, the nut was most likely cross threaded when last installed. If a stub axle breaks at the base of the splines on the shaft, it was overloaded (drag strip type launches). If the wheel stud flange breaks off from the shaft then it failed from high cornering loads.

    For us car guys, its real simple: 1. Repair before replacing. 2. Keep your car in tune. 3. Enjoy what you have because there are people working real hard to take IC engines away from us - for our own good. I strip away the old debris, that hides a shining car A brilliant red barchetta, from a better, vanished time I fire up the willing engine, responding with a roar Tires spitting gravel, I commit my weekly crime...

    Ethanol is also an oxygenate and is used to reduce emissions in states like California. Its a much better alternative the MTBE as far as ground water is concerned. Alcohol (methanol, ethanol) based fuels have been around longer then cars have existed and are not a new alternative fuel source. The benefits and drawbacks of alcohol based fuels are exaggerated by both sides in the debate. They will not reduce our dependence on oil, they will not save the environment, they will not destroy your car's fuel system, and they are not a significant contributer to the increase in world food prices. Ethanol is a fuel just like gasoline, diesel, and kerosene (JP). It is neither good nor evil.

    Maybe put a more appropriate size tire and wheel on the car?

    He was killed saving the lives of his comrades. Regardless of the context, if you can't see the honor and valour in that then I wouldn't want to be hanging off a cliff with you as my only rescuer.

    One of those Nissan (or Hino?) transporters would be cool. I NEED one as a shop truck.

    Good question. You might just want to purchase a buch of used springs and then pick a set that is as close to the stock specs as possible. I bet you can buy stock springs from members on this board, HybridZ, ZBarn, etc. for aobut $5 each.

    Alan, I think you need to get something a little more period correct to haul your Skyline around with:

    Booster lateral hole spacing changed from 80mm to 100mm at some point in the 240Z production cycle. Some indications are late 1972, but I have seen early 1972 automatic cars with the wider 100mm spacing. I sell a MC bracket that replaces the booster and the sales are pretty evenly split between the 80mm and 100mm versions.

    You forgot the "It's Hedley, not Hedy!" gag that Harvey had to say throughout the movie.
  18. John Coffey
    Heddy Lamarr? Harvey was a great comedian and will be missed.

    Figure 4 to 6 hours to properly track the car (thrust angle) and set the toe using the offset rear inner control arm bushings. Its a pain in the butt and I've aligned 6 cars using these bushings. They also wear out in a couple years and you get to do the whole thing over again.

    Where did you source a viscous LSD out of an R180 differential?
  21. John Coffey
    The part numbers listed are for the 280Z, not the 240Z. Please be aware that the gland nut that Tokico supplies for the 3021 and 3013 is bigger to properly fit the 280Z strut tubes. Sometimes you can reuse your old gland nuts and sometimes you can't. It all depends on the gland nut style, center hole dimensions, and how they survive removal. The rates for the springs are correct except the fronts are progressive and the "working" rate for the front spring is 180 lb. in.

    I would be happy with the R35 too. But, your car is rarer and is more visceral. Plus, I can get a R35 this summer just by taking out a big fat loan.

    TC rod breakage is kinda car specific. Its a combination of ride height, the poly bushings, LCA bushings, and driving habits.
  24. John Coffey
    FYI... there's some additional work involved in replacing the front inner lower control arm bushings and the rear outloer lower control arm bushings. In both cases you need to press out the steel outer sleeve of the stock rubber bushing. It normally gets left behind when you burn out these bushings.

    Congratulations Allan! Did you get to hob-knob with the rich and famous? Your Skyline looks great and yes, I would take it over a new one in a New York minute. Goodwood is on my list of must do's before I die.
