I have the slide a links but not the SS springs. In fact I bought the S-a-L from of guy here on FABO just haven't had a chance to test with them yet.
I'd say it's ok. You may have the spring working against the bar, but I doubt it.
Also, for some reason (my luck) the bushing in the front spring eye on my car was a different diameter than anything else so the bushings that came with the springs wouldn't work.
Luckily, I have a bunch of scrap aluminum here and I just made my own bushings. Still, it was a PITA. And of course, no one else ever heard of a spring with that diameter front bushing. I have the only one EVER made! Again, my luck.
