Found Z/28 trailing arms on Amazon, will they fit my 2010 SS?

[LCPLPunk]

Hey guys,

So while looking on Amazon I found what appears to be Z28 trailing arms for about 35 bucks each side. This seems like a pretty good deal so I'm wondering these will work for my 2010 Camaro SS..

Would this be an upgrade?

I'll sell you a 1LE FE6 bits.

Lower control arms.
Trailing arm
Toe rod.

How many miles? How are the bushings? Where are you located?

[JusticePete]

Yes, they will fit. They are a bolt and go.

[LCPLPunk]

Would this be a good upgrade, or would I be wanting something like BMR arms/etc.?

Depends on your application and how hard you push the car. Considering the Z/28 is a track-oriented car, if you don't track your car then you're probably fine with the Z/28 trailing arms, or even the ones you have now (I believe the trailing arms and bushings are the same from the V6 up to the ZL1/1LE). If your car is fairly stock but you run the track occasionally then the Z/28 might be worth the money, and if you have a full-out track car (lots of power and/or big brakes) then aftermarket might be worth it (although the Z/28 has lots of power and huge brakes, so even then the Z/28 ones would probably suffice).

I've got a street car but looking to reduce wheel hop. I know the aftermarket ones are better, but I can get the Z28 ones shipped from Amazon for $100 total, however I'm paying almost half that in shipping for others. :P

[JusticePete]

The easiest way to reduce wheel hop is to get an alignment. Set the rear Camber to -0.50 or less and the Toe IN to 0.12 per side. Instant wheel hop reduction. Set the front Toe to 0.00 and Camber to -1.25 and it will drive and handle better.

How much faster will I eat through tires? And if I get an alignment I might as well add the alignment necessary stuff, i.e. toe rods, etc, right?

[KillboyPowerhead]

What do you mean by necessary? If you mean things actually required for aligning the wheels then what you need would depend on your current configuration and what kind of alignment you're looking for. For -0.5° camber in the rear you don't need anything unless you're lowered too much (since lowering will increase negative camber; not sure how much is too much), in which case you may want to get after market eccentric bolts (cheap) to replace the factory ones which will allow for greater adjustment, and if those aren't enough then you would need an adjustable control arm (not so cheap).

Toe adjustability is more than enough from the factory.

Regarding caster and steering axis inclination (SAI), JusticePete and others can tell you a lot more than I can, and in your case if you're just looking to reduce wheel hop then you don't necessarily need to consider these, but they may be of interest to you none the less. Basically, having a greater positive caster allows the wheels to centre easier/faster after turning, and a greater SAI helps keeps the front wheels pointing forward to improve stability. Caster is not adjustable from the factory, and so you actually need to create your own elongated hole by drilling out the hole for the radius rod bushing bolt, and SAI isn't adjustable unless you install camber plates (these can also adjust caster, or camber and caster at the same time).

JusticePete's website talks about this stuff and a few google searches will find you lots of info too if you're so inclined.

Sorry, should have been more specific. So some things I can replace, i.e. trailing arms don't require an alignment after. If I am going to get an alignment then the things that require an alignment, i.e. toe rods, I might as well upgrade while i'm there. Make sense?

[KillboyPowerhead]

I guess it makes sense to do multiple things at once, especially if you're going to do them anyway. So far on my suspension I've done only sway bars and links but next year I'm planning to do the kablammo with springs, shocks, certain arms and bushings, and maybe even caster plates, and then of course finish with an alignment; this way everything is done at once and so everything stays more balanced and you don't need multiple alignments.

The way to get around multiple alignment cost are to find a Firestone Service Center or a Goodyear Center and get a "Lifetime Alignment Package" less than 200 bucks or you can catch them on sale for like 140. With these packages you can have your car aligned anytime, I try and do mine 3 times to quarterly a year an of course when I do suspension work. A four wheel alignment is not cheap in itself.

[LCPLPunk]

olblue, great advice! I do have a Firestone only a few miles away from me and even better it's about 1/4 mile from where I work. I think I'll wait until there is a sale though because here in Hawaii the lifetime alignment is like $160.
