As title says. The ride on my car (never soft to begin with) got noticeably more harsh today while driving. I get to Taco Bell, park, and examine my car...and it's leaning to the right. Look at the rear wheelwells, and the left has a significantly larger gap than the right :(. Looks like one of the rear shocks blew out. So, I'm looking for all new suspension components - I figure I might as well do springs while I'm at it...ever since the motor swap, the front end sits like a 4x4, and it looks stupid.

Money not really an issue at this point - I'm looking for good stuff that performs well. Anyone have recommendations on brands, product lines, etc?

My requirements: Handling>*. Obviously the car is no go-kart, but I want it to handle as well as possible. All else is secondary.

Car is 1988 Pontiac Trans Am GTA, 350 V8.

Edit for pics
Left Rear
Right Rear

EDIT 2: Accidentally switched sides in pic names :eek: Oops


UPDATE: 05/20

Turns out I didn't have to look too hard to find the problem.

Looks like all I'll need is a BFH and maybe some jackstands? I'm still going to install the SFCs - I may replace all of the suspension anyway, just because.

Thanks all for the help!

UPDATE 6/11, Saturday

Well, finally got a chance to install everything. Drove out to a parking lot (work) that I knew would be empty, and went to work. Started with the passenger side. Everything went well, until I tried to remove the ball joint from the spindle...That bastard is in there GOOD. :| My 16 oz hammer wasn't enough to pop it loose...although I did manage to bend my pickle fork, and put a couple large nicks in it. And I needed a 15/16" box end wrench to get the lower strut bolts out - my adjustable that I tried to use was starting to round the nuts off after slipping a couple times...so I abandoned that plan before too much damage was done.
I didn't attempt the rear shocks + springs yet...I don't think that will be too hard, and I wanted to get the front out of the way.

I went out and got the tools I was missing (boards to place jack + jackstands on, 4 lb hand sledge, 15/16" box end wrench) along with new ball joints. Might as well do those too, at this point. Will probably attempt this again tomorrow.

Parts Installed Today:
One polyurethane front sway bar end link. :(

Lessons Learned:
Ball joints are teh debil.
Adjustable wrenches = good for rounding off nuts. Not much else.
Rubber ball joint boots will not survive the wrath of the hammer and pickle fork.
A floor jack and jackstands with a 3600 lb car on them WILL sink into black asphalt on a hot day :eek:. Hope work doesn't notice.
Bring a cooler and some water when working outdoors in the heat.
Sunblock is your friend.
Make sure you have all of the correct tools in your possession. They will not magically appear when you need them.


Update, 6/12, Sunday

Things went much better today.

Well, I got the rear springs and shocks in place. Those were easy...in fact, I didn't have to unbolt anything except for the upper and lower shock bolts on each side. Once the axle was allowed to hang down, I could just reach up and slip the old springs over the tops of the perches - and the new ones slipped in exactly the same way! (I don't know if that's good or bad...). Oh, and my rear shocks were absolutely destroyed. You could easily compress them by hand...and it took a full minute for them to rebound to their full length :Q. Plus, they were very rusty...I have no doubt that they're the originals.

While I was back there, new polyurethane sway bar end links and bushings went in also...although I did break one of the sway bar bushing brackets that I needed :|. Oh well, it's a $0.99 part, and a 5 minute job to replace it....will probably do that tomorrow after work. Anyways, that much is done.

I then re-attempted the front. Managed to get the ball joint out this time with my B(igger)FH (came out after 4 good whacks)...but didn't have the damn tool to remove the caliper bolts to get the bottom strut bolt out. I got the nut off, but the bolt was rusted inside the strut, and wouldn't budge. I got the top one out with the big hammer.

I did manage to get one of my new front springs in...no coil spring compressor needed. Was a PITA though...the new springs are HEAVY.

The ride back from the parking lot where I'm working was 100x more pleasant than the ride out there. The car no longer seems to fly off the ground when going over RR tracks, is much more responsive, and has much better road feel. And I haven't even done the fronts yet!

Parts installed today
(2) Polyurethane rear sway bar end links
(2) Rear shocks
(3) Coil springs
(1) Polyurethane rear sway bar bushing

Lessons Learned
If you plan on parking close to the grass to get some shade...make sure you know when the sprinklers are scheduled to come on!

Hopefully everything will be finished this time next week!

New car.

*sigh* I figured I'd get responses like this. The handling is honestly not as bad as people make it out to be. In fact, it's not bad at all. It's obviously no comparison to a Miata, MR2, etc, but it's certainly better than it gets credit for.

Obviously there's room for improvement. That's what I'm looking for.

Bilstein or Koni yellow sports if you can afford them and they make them for your car.

I would figure summit racing would carry a variety of springs for you pontiac.

Sounds like you ahve load carrying shocks/struts if your car is leaning because one blew; a 'perfect/ideal' shock/strut is only a damper, not load carrying.

Not gonna happen right now. I have one parking space - on a busy street. No fn way I'm buying a new car just to have some ass total it as it's parked on the street. I'm not replacing it until I at least have a driveway.

Once I move, I will be seriously looking for something else.

Yep and Bilstein/Koni does make them for 3rd Gen F-bodys.

but, never ever post money is not really an issue ever unless your car is 6 figures+ seriously.

You could pour 100k into a 88 GTA....can you though?

If it's leaning your spring is shot. The car is supported by the springs. The shocks are there for dampening.

It's not leaning *too* bad, but it is noticeable. The ride is much more harsh than it was though :(. I was going to go on a road trip this weekend, too - @1300 miles round trip. Kinda kills that - but I'm glad it didn't happen on the way.

Are you like this in real life?

damping, not dampening.

Shocks don't support the weight of the car... if the ride height has changed, something other than a shock broke as well.

heh...OK, I guess I misspoke a bit. I'll rephrase. It's not an issue - within reason. i.e. I'm obvously not going to drop 10K+ on suspension components for this old car, but I'd certainly put $1200 worth of new stuff on vs. the $15 Autozone specials.

In other words, I don't want to sacrifice quality or handling characteristics to save a couple bucks. I"d much rather have good quality components than the few dollars I'd save over buying crap.

Look around and ask questions in This forum

You will get answers from people who actually own these vehicles.

I would look into replacement control arms, bushings, and shocks and springs. More info on specific brands can be found in the forums.

Ok

$199 ea, Front Koni Yellow sports #KON-87411030spor
$106 ea, Rear Koni Yellow sports KON-301265SPORT

$237 set, Hotchkis lowering coil springs, part # HSS-1903

$483 set, front and rear, Hotchkis anti-sway bar set. #HSS-2203

about $1332 total for parts. Plus figure money to replace any worn suspenion rubber bushings, and also any worn steering components, and also to get appropiate tires for this setup.

Get all that and install it and tune the damping on the Konis, and you are set for some pretty good handling.

edit: these prices/part numbers are all taken from summitracing.com, so i'm sure there are some better prices out there, as summit tends to be on the high side for some things. Check out http://www.shox.com for prices, but you'll have to look under a camaro for the vehicle selector.

Thanks all for your help. I'm registered on a couple Fbody forums, haven't been there in a while though...I'll try looking there too, this is the first beginnings of the research stage. Wanted to hear unbiased opinions, and I figured this may be a good place to get them.

I haven't done SFCs yet, but am thinking about doing those at the same time the suspension gets done. Been meaning to for a while now.

TechnoKid, thanks for the prices+brands - that's something I'll definitely check out :) Just what I was looking for. I'll let all of you know what I go with...may not be for a couple weeks though:)

I'd forgo the new sway bars and do the SFCs now instead. Just replace the bushings on the old bars and they will be good for a while.
I had a set of Spohn SFCs welded in and I can tell you it makes a world of difference.

Replacing the steering linkage is also a good idea.

The stock sway bars in my car now are decent....36mm front, 24mm rear - so those can stay for now. I'll definitely upgrade the bushings while I'm in there. SFCs will be ordered probably sometime this coming week. Every thirdgen owner I've talked to who has them say they love them...besides, I've had enough of the "wet noodle" chassis in this car.

My steering is actually still pretty tight - hardly any play in it, although I do need an alignment. I ran over a dead deer the size of a freakin house going about 85 MPH a few months ago - that knocked things a bit out of whack. Made quite a mess too.

On second thought, new poly bushings for the current sway bars would make a world of a difference over the probably shot and worn stock rubber bushings. Bigger sway bars can come later like you said; i was merely suggesting a 'complete package' type deal. Steering linkage is probably shot if it has not been change since '88.

http://www.suspension.com is the place to go for energy susp poly bushings; they carry everything from them, and are 99% instock; they are located in Modesto, CA, a town over from where I live in Manteca. I have bought stuff from the owner many times; he knows a great deal about chassis and suspension tuning.

A blown shock will not lower ride height. A shock absorber does one thing and one thing only; it dampens the rebound of the springs. If the car is lower on one side than the other, either something in the suspension linkage has gone bad, or the spring has cracked.

Blown shocks give a "floaty" feel. They most definitely do not make the ride harsher.

They eliminate a great deal of body the flex that these cars have. Doors close tighter, FAR less noise from the body and interior components, much tighter feel in corners, etc..

Sheesh, you're going to spend all this money, and it's probably a $10.00 sway bar link attachment bolt & bushing.
