Not sure how many others are waiting on the Eibach Fox Pro lift coils, but thought I would share more info I came across on the GXOR FB group:
The specs of the front coils for the TRD Fox Pro setup is 12.6" long, 600lb, 2.5" inner diameter.
The original poster apparently has a friend that works for Fox and got him this info. In discussing lifts, they mentioned one big potential issue that arises from either a spacer lift or coil lift is that the TRD Pro shock has 4 compression and 3 rebound zones, so if you extend (or contract with weight) the coilover too much you will be riding in the incorrect zone,making the ride either too stiff or too soft at an inopportune time.
The Fox employee thought a 0.4" longer coil would be perfect but thought much taller could move you to the wrong zone.
What this mean, is that you *could potentially* use a readily available major brand coilover coil to gain a small lift. One they were going to use is the standard Icon 13" 650lb coil spring. (With it being only 0.4" taller)
ICON 13" X 650 LB COIL SPRING FOR 2.5" COILOVERS
If my math is correct, (And it may not be..not my strong suit) a 0.4" longer spring that also has a stiffer rate should give at least 0.8-1" lift.
I'm waiting to hear back from Ryan at Eibach to hear their thoughts on this.. and what length/weight of spring they are using for their 1.8" lift.
For all I know the info given could be completely wrong... but they did seem to have more info than I had seen previously.
Anyways, do with this what you will, and use at your own discretion.
