Boxing them takes care of the issue, correct?
Its what happens when you abuse the **** out of your car forever.... Boxing them helps, its why volvo had the "taxi" arms.

I have only seen it happen from big impacts, like hitting a curb. Im sure if you are rallying the car it could happen.

Possibly unrelated question. Assuming the car has dampers that can handle it, how well does said car with 500lb front springs handle on the street with daily driving duties or is this limited to a track car?
It'll be fine as long as you don't mind driving an oxcart.

So lack of grip for you pavement pussies huh? Lol

We folded up a set of stock control arms under braking with used rallytires that were up to temperature. Out practicing East of Issaquah before all the gates and population explosion. Ahhhh.... My mis-spent youth....

I used the taxicab/police car control arms.... Boxed them later (overkill) and didn't bend them until they got bashed into the scenery. Gave it the Sellholm Kit for the 2008 season.

The Sellholm Kit made for increased track width and used spherical bearings for all pivots. Did good things for the rallycar.... Hindsight being all that it is I should have sprung for Sellholm's Kit in 2001 rather then suffering through all the disasters that were 'development' screwing around with "Is good enough for World Rally car so we can cobble this Ford trash into it" that (surprise surprise!) worked poorly and made for more bent coachwork. I sure didn't save any money with the GP-A Escort Cossie ish. Lol.... Lessons learned.

Do them up for adjustable track width and caster adjustment. Another 3" of track width did wonders.

Yes they do benefit. I ran a 32mm hollow bar in the front on mine and 16mm rear bar. Balance was great.

Rear springs in the stock location, I assume? And tons of camber and autox slicks, correct?

I thought it was fine with 475lb front and revalved bilsteins. Rear spring rate was 200-325lb (I changed a few times, settled on 250lb rear).

I would not run more than 350lb front on off-the-shelf Koni Sport (yellow) struts. 400lb felt awful, bumpy, bad ride, bad handling. I tried 400lb on my daily driver with the yellows and then dropped it down to 300 or 350lb.

More descriptions:

I have a box of used Bilsteins about to go off for valving so I can hopefully get back to the 450lb+ front spring rate.
