This memo followed in theory right on the heels of the Hemi SS package cars. These were really covert and super trick. AKA The Reeker Files.
Now ya'll know where the madness started.

Contrary to the front end weight loss, I just received my new Launcher springs from Tri-city and they weigh 90 Lbs for the pair.
I'll see what my El-cheapo RJS made in Mehico SS springs weigh compared to these new brutes.
Don't mind the weight here though.

Why no cal-tracs?

I know, only because I want to keep the SS look and also fly respectfully.
In the streets back in the day, those SS springs fooled many a X brand into being relaxed. LOL.
Weight or not, these launchers should be quite interesting. I've studied a few cars running them and the foot times improved drastically.

Gotcha...........and wheelies are the norm from what I`ve seen too......

I'm surprised my Mehico springs hung my tires, but they were sagging so much for some to think that I was baggin'

HANG ON MAN................

I'll start adding to this thread now. I havent even read all of this thread. The 4 washers on the strut arms are almost a lb. 14.8oz to be exact. I just bought 4 grade 8 washers and they weigh 4.2 oz. So over half pound easy and cheap

According to my person scale. I lost 1 lb on the spindle on the left

this is good Six Pack, but the washers are coned/domed for a reason. That reason I believe is to keep the bushings cupped in their positions. I should have made many of these when I made mine years back, but if you search on this long read, IIRC, I explained how I made my coned/domed washers out of aluminum.
IIRC, I placed the over sized aluminum washers over an open round cavity and blew at it once or twice with a rubber mallet and a shaped wood chuck to act as the male.

These spindles are interesting. They seem a little hint different from each other. I believe in Andy Finkbeiner's recent book "B-body performance upgrades" there is mention of a lighter later year spindle. I don't really know if this will apply to A-bodies though.

Did you also grind away at the top portion of the spindle on the left?

I would suggest not to grind at these pieces to much being that they are cast to be strong at different points and some bosses are integral to strength.
Be careful out there and study it all before going forward. Measure twice, then measure again just before the cut as they say.

Very soon there will be some interesting ultra super tricks added here and abroad. Keep an eye out.

If i was using rubber bushings I would have went with a cupped washer but the poly bushings I dont think it matters one bit.

After I cut a section of the spindle off, I used a die grinder and took off the casting ridge all the way around so yes its narrower but I think in a good way. I still think more could come off

Yes, getting the flash and rough edges off to smooth will keep 'em from creating stress cracks.

Look at the new beefy front eye bushing in my Tri-city Launcher springs compared to the Mehico springs. Thank God they are of aluminum. LOL.
So far the Launchers weigh 45-1/2 pounds each. I'll weigh the old SS springs later today.

I'm running these QA1 strut rods, my spindles are from a drum setup with wilwoods.

Darn Garnet, my old Made in Mehico Ss springs weigh 42 Lbs for the Passenger with 8 leafs and clamps.
38-1/2 for the drivers with 7 leafs and clamps. Gained back 10-1/2 Lbs on sprung weight.

What do Cal tracs weigh with the bar

I have some mono leaf springs and a set loose if nobody has weighed them yet.

go for carbon ceramic rotors, save about 15 lbs...tim
