Stiffening Satellite Suspension

[oxytousc]

Hey guys...got some suspension questions. First project on my 73 Satellite/Roadrunner clone is rebuilding the front end, it's toast (includes k-member replacement). My question is, I am planning on this car being a daily driver, putting down between 450-550 hp and I want to make sure that when I start the rebuild I build a suspension that will be responsive. Can I get some guidance?

My general thoughts are PST Polygraphite Super kit for the front and rear bushings. Planning to fit the largest sway bars I can find to the front and rear.

I need guidance on the following:

* Shocks?
* Solid (aluminum) v. Poly K-member body mount bushings?
* Leaf springs?
* Torsion bars?

Again, this is going to be a daily driver, but want to be able to take it to the track if the urge strikes...any recos are appreciated.

Hey there. I can say from my experience that the PST Polygraphite kit does wonders for the ride. I did front and rear on my Coronet and I love it! I also went with the PST big block road race torsion bars and Anti-sway bar set... It honsetly feels like my '84 Vette used to... I went with KYB Shocks and Mopar leaf springs. Nothing fancy with those but the whole package is like night and day! Hope that helps. Haven't done anything with the K-member yet. If my car wasn't down for my rebuild I'd cruise by and let you drive it to see the difference since you are only 30 minutes or so away.

Thanks, wookie, definite help...yeah this is my first mopar project, so I'm still learning a lot.

In terms of shocks, I'm also looking at the Koni drag shocks, but am having a hard time making a decision...

Since you're local, any good recommendations on mopar parts stores/junk yards in the area?

 

[wookie77]

Ummm Not really...LOL

I like to go to Ecology Auto wrecking in Rialto. Right now they have 2 '63 Dart GT's and they go through inventory quickly.(unfortunately) I wish I had way more room and money. Pricing is good... There is also Mopar Flats in Phelan in the high desert, a guy named Darryl runs that place. He has parts but is pricey and hard to get a hold of. There is also veteran MoPar racer Bob Mazzolini in Riverside. He is a nice guy, full of real world info and has a small shop with quite a bit of inventory. I just recently discovered Wildcat Mopars in Oregon. I know they are not SoCal but they have 900 cars in their yard! Hope that helps.

Thanks. Yeah I spoke with Darryl a few weeks back about a k-member, he wanted like $250. Ended up going to Sweetwater Auto Wrecking in San Diego...Mark there had great prices and was super helpful...well worth the drive! I got a k-member, spindles and seat belts for what Darryl wanted just for the k.

Ok that's cool. Oh there is also a place in Ontario called Bill and Ed's. They are a Mopar only yard. I got my front disc brake conversion from them a few years back. I am still searching out places to get parts from.
And in response to your " Thanks" You are very welcome. Anything I can do to try and help a fellow MoPar owner.

 

[oxytousc]

How thick are the torsion bars you picked up? Did you like the PST ones better than the Mopar ones?

 

[wookie77]

Well I bought them about 6 years ago and I beleive they were just over 1". I think they were just under the heaviest ones they offered. I can Mic them tonight when I get home from work. I have not used the Mopar Performance ones though so I can only compare them to the factory ones. Between those and the anti sway bars... The car feels like it's on rails. Almost no body roll in corners and the steering seems WAY more crisp as a result.

 

[oxytousc]

Nice! I am thinking I just go as thick as possible...

OK, with the Koni drag shocks, I gotta ask what your driving style is gonna be. Corner carving or straight line killer? Me, I am going with the parking lot Zamboni/Nascar style. I went with solid K bushings but am thinking that I am going to keep the control arm bushings in rubber. At least on the lower arms, I am not to thrilled with the hold that polys have on the shafts.

 

[oxytousc]

Rev. my driving style is really a mixture of both...in looking at the Koni's again, I am guessing drag shocks are going to be WAY too stiff. Yes? What shocks do you recommend? Have you tried the KYB's that Wookie recommends?

I am a reformed Ford guy, where there were a ton more shock options, so any suggestions are much appreciated.

I was thinking of doing poly k-mounts and poly bushings all the way around...do you think that I should go with the solid k-mounts on a daily driver?

 

[oxytousc]

Also, do you think front adjustable shocks are the way to go? I can only seem to find the KYB Gas-a-just's for the rear...

 

[oxytousc]

Nevermind, disregard my previous post...I was being stupid...still looking for shock recommendations though...

I went to summit and got everything in polyurethane but have yet to try it out.The only problem I had was with the strut rod bushings they are to small I think they are for a 196?'s Satellite but they say they are the rite part.???Check it out....

 

[oxytousc]

Nice! All the energy suspension stuff?

 

[74sundance]

Oh yes,I should have said that

 

[Revhendo]

I'm using KYB's (GR2's?) on the nose. I have a pair of Monroe truck shocks on the rear. My reluctance to use poly's on the LCA's has to do with the experiences I am having with my Valiant and the arms shifting on the poly bushings.

I don't think you will want drag shocks unless you are looking for 1/4 mile straight line driving. Front drag shocks are normally designed to allow the front end to come up fast, but go back down slower. This is to improve weight transfer for traction.

 

[74sundance]

KYB's GR2's..... That's what I have in mine also, but I still have not tried them.....

 

[oxytousc]

Alright, sound's like the KYBs it is!
