Deciding on LCA's.

SPC is fine if you daily. Don't do performance driving on them. SPC arms have been known to snap for performance driving on multiple platforms. The same thing will happen to the lower end LCAs.

Which part of the LCAs you mentioned will fail? Is the heim joint or the actual aluminum structure itself?

I'm looking at the "lower" LCAs myself to add stroke.

Usually the joint itself. To reduce cost, the rod end material, sizing, and strength rating are compromised. There is a prototype LCA being tested right now that addresses the stroke issue, but we can't talk about it.

Slot the stock LCA's

I just noticed the Buddy Club rear LCA also lowers the damper mounting point. Anyone care to guess by how much? My guess is around ~15mm

Even the new design ones that are essentially the same construction as stock? I've read bad things about the old style, but have heard the new style ones are much better.

For reference, the ones pictured are the new ones, both styles shown in the video:

Well, it's about time!

My concern is how SPC still released a bad product into the market knowing it was bad to begin with. Only until there were sufficient issues did they decide to change the design. The engineering ethics involved in that release is like the Space Shuttle Challenger. Either way, I would not consider SPC to be a high quality design. While it might look the part, it does not always perform the part.

On another note on LCAs, most LCAs on the market have setting creep. The less camber change, the higher quality the LCA. SPL is probably the best LCA out on the market right now since it has had zero alignment creep after going through multiple track days. That's our experience after testing multiple LCAs already on the market.

Would it be feasible to drill safety wire holes in the adjustment nuts and safety wire them to keep them from creeping?

Possibility but not a guarantee. Something else is giving which causes the creep.

That's unsettling. The only part that should be changing length is the adjustment mechanism. That's why I don't like the slide adjustment LCAs or offset bushings. Or camber bolts, for that matter. They have the potential to work themselves out of position with time.

Most people won't notice the changes. We're kind of a different species when it comes to really operating at the limit........................

Then again...that's what we're here for.

If you look at some of the steel LCAs like the Buddy Club example posted earlier or Cusco, they don't even look that difficult to make. Have you considered just making your own to better fit your needs?

We did, but the market is too saturated and we feel it's not necessary to design something that has been addressed by multiple large manufacturers. We have a design developed if we want to pursue, but right now we'll push the Cusco, Whiteline, and SPL parts. SPC is fine for people who need a LCA but don't intend to do performance driving at all.
