Suspension Overhaul Questions

[Communistwookie]

Hello all,

I have been looking all over the forums and seem to be getting bits and pieces but trying to get a comprehensive list of what i need to replace.
The chassis has 214k miles on it and is all original as far as i know except for the coilovers and inner/outer tie rods.

would like to completely to through the suspension in one shot and be done with it and not touch anything for a while, i am open to aftermarket/OEM parts, not looking to go crazy with the price but don't want cheapo parts im going to have to replace in 6 months.

So far i have these picked out, feedback, alternate parts and missing parts are much appreciated as i know i am missing stuff here..

Energy Poly Bushing Set, Rear - http://store.driftmotion.com/static/i-83127g.php
Energy Poly Bushing Set, Front - http://store.driftmotion.com/static/i-83126g.php
REAR SUB FRAME BUSHINGS - http://store.driftmotion.com/static/i-bpm-202-06.php
Spherical Bushings ( i need of these from what i understand?) - http://store.driftmotion.com/static/i-sphericalbushingformk3suprarear.php
Steering Rack Bushings - http://store.driftmotion.com/static/i-steeringrackbushingsmk3.php

Do i need new Control arms? i have read that front upper ball joins are not replaceable? how are the dorman control arms? any other suggestions? Control arm end links? stabalizer bars? Mk3 supra suspension is different thatn what i'm used to so i'm not sure what all would need be be gone through or can be replaced.

You would need front subframe bushings.

Also can get upper control arms and ball joints from rockauto.com

found dorman's for less than half the price, my uncle's run a repair shop for along time and has a very good rep. he's spoken highly of their products....

high performance is another issue though, I'd want to do some more research and get good input as to what exactly is built the best

Not looking to build something that is unbearable in the real world. Some mild upgrades for occasional autocross would be nice but primarily this is a highway cruiser that sees autocross maybe 3 times a year and once to the drag strip. I'm not real competitive in these events and they are more for fun. So what I'm looking for I suppose is quality parts that are going to last and keep the car from being unpredictable when I want to have some fun.

also might think about new ball joints and tie rod ends

Forgot to mention I replaced the inner and outer tierod ends already car wouldn't even align correctly without replacing those. I didn't replace the ball joints that the outers connected into, good point though I'll add that to my list.

ronnie k also makes a lot of bushings for out cars. and he can use different compounds depending on what you want to do with the car

no sway bar considerations? or endlinks? those OEM links, the plastic ones make me frown....

 

[Insidious Surmiser]

hm. I've heard those endlinks are fine, I'm'll wait to see if they snap :icon_bigg

I think he wants to cover the basics first though. Which is a good idea.

 

[hvyman]

They can eventually snap. It's not a huge issue with stock sway bars tho. With stiffer sway bars adjustable ones are wise tho the metal link will work as well.

 

[Communistwookie]

How are these? http://www.suprasport.com/ST-Anti-Sway-Bars-_p_146.html I hear white line is the way to go but these seem fairly priced in comparison. Are the Moog endliks good or am I better off getting adjustible end links?

I haven't seen any "front subframe bushings" what exactly are these?

same idea as the rears, and RonnieK makes them.. I would also buy rear bushings from him in lieu of the Beech Performance units from Driftmotion.

Have you verified you can actually remove your cam bolts? On my car those things were perma-rusted to the bushings and had to be cutoff. For the fronts I had to saw off the lower a-arms to get the bolts out.

just did mine last night with a torch.

were rear spherical bushings brought up? im glad i replaced mine even though they had no play, i feel a lot more confident about my suspension now, just gotta do ball joints/sway bars and subframe bushings

 

[hvyman]

Ya mine are seized. Not looking forward to doing them. My rear sphericals also have play.

What did you use for the spherical bushings? I was thinking a socket and a pulled to press them out on the car.

The Dorman front upper control arms are priced very low, compare to others. should this be a concern with quality?

If you find out let me know as I have been eyeing them on rock auto they seem well priced but don't know about the quality

My concern is with the ball joint. I would replace the bushings with Energy Suspension.

Seems like a lot of work to replace all the bushings, you should just us know how much of a difference it makes. My car only has like 150,000 km's but it seems to be fine but I heard they can make a huge difference for autocross. I have tein coilovers and ST sway bars on my car. The coilovers are set nicely but it was the swaybars I noticed the biggest difference with, it takes out like 40% of the bodyroll when cornering so you feel tight to the ground. I also bought new rear endlinks as I believe this is where more of the stress is. If my fronts break I will be looking at some beechperformance ones though.

As for the whiteline sway bars they're top of the line. I believe you can search for the chart in showing the differences between a couple brands and they come out on top but are also the most expensive. But if your not serious on racing just putting any sway bar on will make a noticeable difference.
