We have a set sitting here but Sean has been a bit distracted lately. We have a jig and can build more but the best way to kick Sean into gear on something like this is to blow his phone up.
I’d like to see side-by-side comparisons of the SLR and stock arms so I can see if they really offer the same or better clearance because from the pic you’ve posted, they sure don’t look like it.
The stock arms don’t break when you bottom out either. They just bend. I have a LOT of personal experience with this. Maybe you mean the spring perch breaking for various reasons, but that’s not the same thing as when the arm bottoms out on the chassis.

Bend? Wow. I figured they would just break.
also, suspended? lol

Not from bottoming out (due to a shit coilover design by a certain company) I've broken 3 RUCAs so far. Adding Bimmerworld seat reinforcement plates seems to have stopped it, but the additional camber adjustment would be nice.
Piner- that's exciting! Except that I already of separate coil/ shock suspension, so I see no reason to eliminate the spring perch. I'f I'm not super low and dont have any issues with my rear alignment since I did turner camber arms, what'd be the benefit to going for tubular upper control arms?
Nova- what are you doing when breaking the UCA? I've been at it for 3 years and havent broken or bent one yet, as far as I can tell.
Also- saw the suspension. I was reporting any post that he was unpleasant in, but I though he'd actually been behaving for the most part recently. still, have to laugh.
Keep it simple: half gutted '01 330i, welded diff, BC coils, SLR Super kit
Nothing out of the ordinary, I broke both sides in one 6 hour track day. Maybe a few dirt drops in the mix, but nothing crazy. Just kept seeming like my rear ride height was getting lower and lower but I was too lazy to check until the springs hit my axles.
The BCs I went years on. They had a wide flared part on the adjuster to distribute the load. The FA adjusters don't have this wide base, instead they have a stud coming out of the adjuster and a big nut. When you bolt this to the spring perch it either concentrates the load too much on a small area, or it wrenches back and forth on the aluminum. I replaced both arms, and one did it again after a second track day. I replaced it again and this time didnt tighten the nuts, just put them partway on with an assload of loctite so they wouldn't fall off and one hasn't broke since.
On my 510s, I don't even have the nuts on them. It's been fine so far. If I break them, I plan to go with E36 uppers.

Really? I have my shocks adjusted so the spring is preloaded a tiny bit at full droop. Plus the E30 was WAY worse than that and the springs never fell out.
