I'm planning to install Megan EZ coilovers and wonder if anyone knows how low I can go and still maintain factory toe. I can tolerate up to -1.5 degrees camber, so I'm not worried about that. I just don't want to have to mess with aftermarket toe kits. Thanks.

 

I wish I knew. I would like to know the answer to that as well. about to lower mine a bit to go with some new summer "shoes".

 

My GS is dropped about 1-1.5" on H&R springs and Bilstein B8s and no alignment problems. Toe is in spec with -0.5 front and -1.0 rear camber. Unless you're going crazy low and looking for tucked wheels alignment shouldn't be an issue

 

 

The lower you go, the more camber you'll end up with. Mine is down about 2" on H&R coilovers, and with the OE camber adjusters set as positive as I can make them, I still have -2.3° camber front & rear. I could correct this further with aftermarket arms but I don't drive the car enough to justify it.
A 1.25"-1.50" drop is about as low as you can go without ending up with more than -1.5° of camber. When I first installed my H&R coilovers it was lowered 1.6" and ended up with -1.75° of camber with the OE adjusters maxed-out positive.
Another thing to consider is wheel fitment - with an aggressive wheel/tire set-up like mine, the tires would rub if I reduced the camber at all.

 

I'm lowered about 3.5 inches and I can get the rear camber to -1.7 degrees. The front on the other hand is -2.8 degrees.

I agree though, a 1.5-2 inch drop should be fine to keep you close to spec.

 

It's interesting that most responders seem to think that camber is the main issue. Actually, toe is much more critical to tire wear. That's why I initially stated that I could live with -1.5 camber, but need to keep toe close to zero.

 

You won't have an issue with toe with a small drop in my experience. Both front and rear were within spec

 

Never had a problem getting toe back within spec, so probably why I didn't bring it up. You're right though, you can't really change one spec without having an affect on the other. Most guys even-out the camber first and then set the toe.
