**gtpinsc** · 12-30-2010

ok car is gonna have surgery soon.
so far i already have:
F bodies with powerslots and hawk pads
stainless lines
speedbuilt STB's
GMPP sways

on my list is:
KYB agx's
KYB strut mounts
eibach prokit
poly motor mount
poly dog bone bushings
poly control arm bushings
solid trans mount
poly engine mounts
poly sway bar bushings
tie rods
sway bar end links
ball joints
BMR trailing arms note: all poly stuff will be ZZP as of now.
vinnys spacers- added.
is there anything else you can think of that i should replace with 150kish on chassis? or other brands that you would go with. trying to keep it at or under 2000 bucks.

your gunna need the engine and tranny spacers to get the geometry close to stock to get rid of the lowered vibration. cant remeber who makes them or where to get them but im sure bio will be stopping by before long and he can give you those deatails.

**gtpinsc** · 12-30-2010

talkin about the vinnys cradle spacers? wasnt sure if eibachs were low enough to require them.

**carl06GT** · 12-30-2010

yes anything lower then the vogtlands you will need the vinny spacers

**The Guz** · 12-31-2010

Are you sure you want to go with eibahs? They have a rough ride and tend to sag in the rear. Also you can get the UMI trailing arms cheaper than the BMR's.

**gtpinsc** · 12-31-2010

im open to suggestions on springs.... i dont wanna go super low... but i want lower than vogtlands. UMI and BMR about the same as far as quality and performance? also opinions on addco sway bars?

**Bio248** · 12-31-2010

if you dont want to go super low, but would like to stiffen things up i would recommend SSC from ZZP. eibach and B&G will ride less rough than SSC, but they will be lower (read: will rub more with your 20s on).

you'll probably be better off with the spacers vinnie makes if you go with a set of eibachs, but with SSC you might be okay.

I'm currently in the stages of building a new suspension. I have similar set up as you waiting to go on in the spring. AGX's, I think I have settled on the B&G springs, UMI trailing arms they seem very beefy (I got mine for a GREAT price I wouldn't go with any other bar), and gmpp F/R sways.
As for the springs I think the B&G's are going to ride lower than I really wanted to because I do DD this car year around and going to carry my son who of which is a infant. But when paired up with the AGX's I think I should be able to adjust the ride comfortable enough where I carry him with out jarring him to death. I am still torn between the Vogtlands which I wish lowered the car more and the B&G which I think will be lower than I really want. But like the tint I now wish I would've went darker, I feel like I should go lower than I really want.

I've heard some negative things about Addco sways about fitment issues. I know for sure when it comes the MC's, Impala's they don't fit at all. I thought there were even issues with the GP's as well but I can't recall.

I agree since your going through all of this you might as well go with the better option for your car and getting the spacers.

where did u get the UMI's? and how much?

**matt5112** · 01-02-2011

get new LCA's.

a new BJ will mean less torque steer and a new front control arm bushing is always good. Mine were failing at 85 K miles.

Get the SLP sways and then find some energy sway bar bushings and you'll be set there.

Get MOOG front and rear sway bar links though.

**gtpinsc** · 01-02-2011

any special lca's? or just go stock?

**matt5112** · 01-02-2011

WBS perf ones are decent.

but they're just stock ones with poly bushings in them.

So if you can do better for ones with greasable BJ's cheaper then do it and install the poly bushing yourself.

I got AC Delco ones pretty cheap, $90 a side.

The MOOG sway links are awesome.

Specifically the rears. They're larger than any others and have greasable joints. Unlike most others.

I bought them off a member on the forums here and $30.

**The Guz** · 01-04-2011

You can get the UMI's on ebay for about $100. Some have said the GXP trailing arms are the exact same thing as the GMPP trailing arms. Not sure how true that is. Also I would just stick with the GMPP sways that you already have. I would get the spacers when going lower than 1". Geddy Lee has some for sale in his demod thread or just contact Vinnie.

Just to let you know, I had B&G springs at one point and they do sit lower than what they advertise. I have a small sub box in the trunk and my rear sat lower than the front.

Why not convert the agx's into a coilover setup and be done with it?

not everyone is that comfortable doing that kind of fab work. it isn't exactly a beginner mod.

**gtpinsc** · 01-05-2011

id buy coil overs before i attempted to fab them.

**BillBoost37** · 01-05-2011

You mention trailing arms. How about the toe links and lateral arms?

**matt5112** · 01-05-2011

You should get the complete BMR kit if you're going all out.

Downside with the BMR trailing is with smaller wheels they can have clearance issues with the grease nipple.

**BillBoost37** · 01-05-2011

HT Motorsports haven't given me any issues. Erik is a cool guy with much better pricing than BMR if you are looking for BMR quality at a better price.
