what's the total height of the Titan compared to the Bilsteins?
If its shorter, as per Necc, this would actually compress the springs further, making it extra stiff, and lower per normal
so the bumpstop will definitely be compressed and thus its life span reduced, or maybe it won't be effective at all
lastly i think because of its inverted design, a matching spring design, rate and length should be installed with it, and not Eibachs
Fabs,
you didn't mention if you changed the rear combos or not, all thses while what was the rear setup, and changes made when you did this swap? as i recall, if rears are tilted abit, the front will be compressed
