mr. p body, i'm not a big fan of pickle forks, although i have used them before. it seems every time i've used them, the boot got tore up no matter how careful i was using it. any other suggestions ? Oh well.... when I was working on the pre proto F-body front suspension I had to pull about 12 ball joints a day so I could set up for another front end(this was the transverse bars).. yeah once in a while I would tear a boot.. but not often... I HAD to make sure the fork was under the boot.. on both sides of it.. I actually cut the angle down on my pickle fork so it went in on a easier angle EDIT plus I always put grease on the fork so it slides on the boot

My comment on your lightening, IMO there is one glaring point where a failure might occur, (EVERY item has a failure point) its on the second LCA pictured, on the top of the LCA (which in use is the bottom), approx 2"? to the left of the pivot point, right above where the adjuster loads against the arm. That area is in tension under load, with the removed flanges in this area. I think this one area is overlightened relative to the rest of the arm, and simply adding back minimum flanges on both sides, or boxing the two sides together would reduce the stress concentration. Is it a big deal, not likely. This mod maybe already in the cards as I have no idea if this a progress pic or completion.
And weights before and after would make for good discussion.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

That's good, but it would be the area I looked at first when doing regular check overs.

here is a pic of my stock shock towers. Do you guys that have done a front coil think they will be strong enough for coilovers?

also thinking about hole sawing my frame connectors. I have a 12 point cage in the car anyway and was thinking the heavy 2x2 square tubing is just adding weight

Here is what Im thinking. If I go coil over, i can hack my lower control arms like Steff did. Maybe even more. I lose the weight of the t bars, the adjuster bolt and tab thing, cut out the lever. Maybe take a good look at the spindles for weight reduction.
Magnumforce sells coilover kits for to much money to use in the stock shock mount.

I got a quote a while back for $25.00 per bolt. That is of course, titanium units, not Aluminum. But it only shaves about a 1/4 Lb.per spindle since Titanium is only about a 1/4 lighter than steel. Only good if you're chasing ounces.
