These are from SPC....

05 - UP MUSTANG FRT This adjustable strut mount will give you an additional 4 degrees of camber or caster. By replacing the existing upper strut mount and utilizing the stock strut bearing and spring plate, you will maintain factory ride and get maximum adjustment.

Note: Modification of the strut tower opening will be necessary to gain access to adjusting bolts.

What are you doing to the car? Any of the 'normal players'-steeda/bmr/Eibach springs can be fixed with a couple camber bolts.

 

I'd stay away from anything that requires modification of the strut towers to adjust them (unless it is just a slight increase in the size of the 4 mounting holes...).

Ground Control offers a nice set , as does K-Mac. http://www.wildponymotorsports.com/p...idCategory=438

Another option is from J&M (http://www.americanmuscle.com/2005-c...er-plates.html), for about $100 less, and also Steeda, but there is not caster adjustment.

MaximumMotorsports told me in a recent email that their caster/camber plates would be out in "4-6 weeks," but I'll take it to mean the end of Summer.

How much adjustability do you need and how frequently will you be adjusting? If it is a one time shot to get into spec, you may want to consider the Ford camber bolts or the Steeda billet camber adjusters.

 

I'm trying to stay away from camber bolts.

Bingo, this was taken from their instructions, “On car adjustment of this part requires the upper strut mounts body support to be cut or drilled to allow access to the adjustment bolt heads.” The SPC plates don't adjust caster either and cost $320, not worth the money. I've heard some negative things about pre-05 MM plates. I don’t think Griggs offers them yet and I assume they will be 3-bolt design. I didn't know about K-Mac.

I'm leaning towards K-Mac anyone out there use them? Anyone know the adjustment range they have?

Thanks,

I recall the MM plates for the pre-05's as the plate to use.

Every auto-x/road racing 05+ mustang I've competed with is using the Ground Control plates. The K-Mac plates do look nice, but I wouldn't want to be the first to try them.
