umm i think you are in the wrong place, this is the SPI section not the suspension or the SVT section.

 

yes u can go 2 inches. ive got the eibach sportline springs and they drop it a max of 2.3 inches.

 

can i do 2 inches on 18's.. I wish i would have got 16's
but to late now

 

Moving to Wheels, tires & suspension.

 

svt03man;
Just remember when you're looking at drop ratings/listings:
The SVTF won't be lowered as much as the listings show.
It's already sitting 1/2" to 3/4" lower than the standard models.
So, if it says 2" drop, you're only going to go down by 1-1/4" to 1-1/2" on the SVTF.

 

Wheel size (diameter, offset and width) and tire size are also part of the lowering equation.

 

you may have a rubbing problem around corners with 18s... i have heard of that with 2" drop and 18s... as said above, it depends on wheel and tire demensions....
