For some of us that already have something like the full SPL arms up front that do roll center correction, how much does that do vs these. I'm sure these were designed around all OE arms up front so all of the correction is based on that.

So if someone has all the SPL parts are they 50% to what this achieves....is it 75%, 90%, etc?

I know the SPL fixes roll center but I'm not sure about the other details that these address. I'm going to guess the proper upright is still the superior product but like mentioned above, how much better vs someone already running the SPL parts?
