springs on vert / suspension w/ 18" fans

anyone know if Vert. GT has different springs then the coupe GT?

how about a difference in springs, swaybars or shock valving for GT's with the 18" wheel package
(read somewere that suspension settings are different to take advantage of bigger wheel/tire)

my '05 GT coupe has Eibach pro-kit coils and sits a full 2 inches lower in back and 1.5 lower in front (the left side sits a little higher, could be because of shaker 1000 box/amp in right of trunk)

my father just picked up his '06 GT vert. (toungsten/red w/black top)
with 18" fans

he wants it lowered like mine, are there lowering springs specific for verts?
I can't find a true answer. ie, a place on ebay shows a specific Eibach part # for an '05 GT vert as 35103-140 while Eibach's web site shows same # for both coupe and vert 35101-140

any sugestions on what brand/type lowering springs to go with for him, I think if it sits as low as mine he may find the ride or the extra scrapping to much (he will be driving it alot)
all other bands (H&R, Steeda, Saleen etc. list 1 inch drop in rear, one inch just seams to little for this car

anyone heard of shorter rear bump stops available or cutting down stock ones?

some answers

today, talked to Mark at Eibach

he told me, they (before now) were using the same part for coupes and verts and were developing a vert specific spring, but the coupe version will work fine.

I guess my timing was good because the first vert specific batch (35103-140) is available for shipping now. the difference is a increase in spring rate to compensate the overall weight difference and weight distribution difference

he also recamends cutting about a 1/2 inch off stock bump stops in the rear (at least for my coupe)

or, order there shorter bumpstops (p# BS 45001617) (included with the lower Sportline kit)

Laurel Mountain Mustang, gave the best deal for both orders
have you removed and felt how heavy shaker 1000 unit is?

the panhard bar / track bar or mounting should have no influince on ride height

the posibile/combined reasons for a car sitting a 1/2" lower on right

-more weight on right "most likley"
-mounting point vairinces
-some type of driver compensation?? (car with stock springs sat lower the same amount)

I believe it sits higher on the left because of the panhead bar attachment placement? The amp is NOT that heavy:eyepoppin
KiLLeR_WoMBaT, didn't mean to come of as a smart arse, just was curious if you had removed the shaker unit and felt the weight (i haven't)

on the panhard bar it is a locating link only, you could remove the link and the car body would shift side to side but not up and down

If I ever get the chance and remember, I will measure the ride height with someone in drivers seat.
