Just finished installing the Eibach Prokit this afternoon.I am running Toyo Proxes T1S 19/245's in front and 19/275 rear.Pretty pleased with the results.The car lowered as advertised 1-1/4 front and 1" rear.I don't think they will settle much (being progressive springs). Camber needed to be adjusted rear, and I am within spec's with the stock camber adjusters.The fronts needed minor adjusting (toe in toe out) with slight negative camber(no front camber adjustments provided) Fender clearance is more than sufficient,in fact, another 1/2" or so would be nice, however, after market camber adjusters would probably be necessary.I hope this info was helpful to those looking at the Eibach Pro Kit.

Just got mine installed too. Haven't had it aligned yet, but thanks for the heads up

 

>I don't think they will settle much (being progressive springs).

actually, it is usually the exact opposite. Linear springs don't settle as much.
Your prokit will settle close to 1/2" wait and see. then get your alignment
done again. my rear sits -1.4"

 

I hope they do settle a bit more, and yes, another alignment would be the thing to do after a while. In fact, most new cars may be out of alignment to a certain degree from the factory since they run 30 to 40 cars through a standard predetermined alignment, then recalibrate.

 

Mine settled just right
