have roush rears..question about fronts...

[02GTRX]

after lowering the rear with just the roush rears it now sits about .5" lower in the rear than the front. If I get the roush fronts which lower it 1-1.5" will I need caster/camber plates and all kinds of other crap only to find that the tires will still prematurely wear on the edges even after alignment?? this was a big problem on my 02 and not something I want to deal with on this one so if theres any other options Id be glad to hear them. BIG difference with just the roush rears btw, no more axle hop over bumps and reduced wheel hop.

That's weird, every car I see with just Roush rears still sits lower in the front. Is the pic in your sig with the rears on? If so it looks fine to me. If it's a problem for you I would just get the front's. Any more pic's? I want to get the rears also and would like to see if what you describe happens to me if I could tolerate it.

I just posted some in the "I want to buy 20" wheels" thread. You can kinda see it there. The pic in the signature is stock springs. Even with the stock tires and wheels it was lower in the rear. I'd say its pretty noticeable.

Yeah, that is weird. The Roush Rears only definitely evened mine out. Have you done any weight reduction up front?

In any event, adding the fronts will not be enough to need caster/camber plates. Just come camber bolts, at the most. However, if you get the fronts that match the rears, I believe the drop is 1" or less. An alignment probably wouldn't even be needed.

It all depends on whether or not you're running a staggered setup.

My alignment came down to -1.3 Camber up front after installing the Roush springs/shocks with GT500 insulators. the maximum allowed by Ford is -1.5 which is a good amount of negative camber. Normally I think the car sits at -0.5 so you're tripling your camber and by that token reducing your tire life. If the tires are staggered then you'll want to get some plates or a correction kit of some type. If not just rotate your tires more often and offset your wear.

The advantage of getting plates is that you'll get rid of the weak stock insulator which fails on lowered cars. This will give you easier adjustability if you do that on your own and you'd be buying only one part vs a mount and a correction kit/bolt. The disadvantage of course is price as quality pieces aren't cheap.

No weight reduction..maybe the gt/cs rides alittle lower in the rear? That's about all I can think of...

Was it the blue springs or other Roush springs?

I installed the Roush suspension and have had no tire wear issues, the car has 13k miles on it with the current suspension. I have the shocks and struts too, but I don't think they would affect anything as far as tire wear. I did get an alignment after the install as a precaution, but it didn't really need any corrections.
