Not if you do it right.

Not on my car. The suspension is from the stone age and doesn't change with height. I wish it did, because that would mean it would handle nicer. Oh well, struts up front and a trailing twist beam in the rear are light and cheap.

yeah but you can't do it right with a drop spindle on all cars. esp. not on the majority of cars people on this forum drive.

But there are ways to correct the alignment and wear issues. No single solution is correct for every vehicle, but there usually IS a solution.

If over pressurizing the tires on these light weight cars doesn't show much ill wear...I don't see how having the wrong camber will either.
It will affect handling tho on the bigger drops....as not many cars have enough adjustment in them to bring the specs fully back in line.

Typically, camber angles of up to -1.5 degrees really don't present much in the way of additional wear. Going much beyond that begins to promote more distortion of the tread blocks, heating, and increasingly accelerates wear the shallower the depth of the tread becomes.

So a little is no big deal, but allot can destroy a set of tires very quickly.

Ok, sounds like it may be more hassle than its worth. Just looking for a little something to help me out this Spring break my record mpgs...

On some cars, like my other car, lowering it affects camber and toe at the same time. It's toe that quickly kills tread life. Just be aware that if you see too much negative camber when you lower the car, the toe may be off too. Make sure to reset toe to factory specs, and get the camber as close to spec as possible.

I like to keep camber as close to zero as possible since it keeps the tread flat on the ground to minimize distortion and flexing, which increases rolling resistance.
