Default 122 Suspension and wheels

My newly acquired 122 needs some suspension work and tires. Everything is in good shape but old enough that I want to replace the rubber for peace of mind. So might as wheel get mods out of the way while I have it apart.

I like the stock look. Is there a good set of wheels that will fit the 122 in a 15x6 size that fit the stock hubcaps or should I just get the stock wheels widened? The 165 width tires are frighteningly skinny.

How are the IPD sway bars and sport springs for this car? The roads here in Santa Cruz are rough. As a result I would be hesitant to go for a very stiff suspension and will probably be sticking with 15 inch wheels for more sidewall. For reference I was rather happy with '79 GT springs and bilstein touring struts on the roads here. How would I get similar stiffness to that?

I also ran poly bushings and avoided them for the rear trailing arm mount on my 240 because they bound and caused wheel hop when I was running them. Are there any key locations where I wouldn't want poly bushings on a 122?

Lots of Ford wheels and the 15x6 Mopar B body cop wheels fit 122s.

Good luck with the hubcaps unless you have the centers professionally installed on some new barrels.

The 165 tyres will work fine for normal and fun driving but if you really go hard then 185 is a good choice. 185s will fit on your rims. You can get new 5.5inch rims.

Rough roads I wouldn’t upgrade the ARB, that is a upgrade for smooth roads. Standard or slightly uprated springs, gas shocks (Bilsteins, KYB or Gaz are pretty much your choice) and poly bushes.

New steering ball joints
Idler arm bush wears out quickly, this is a good upgrade: https://www.skandix.de/en/spare-part...ipple/1060063/


Alignment:
Toe in 0 to 2mm
Camber -.5deg
Caster check the green book
Tyre pressure correct maybe slightly less in the front.

Then see how you like it with a good reconditioned, slightly uprated and correctly setup suspension and steering before changing anything else.

I'd reccomend 195-65-15s, anything wider is going to drive like doggy do on a vintage Volvo.

195 -65-15 tyres work great
With very rough roads I would go with rally springs myself and even consider 25mm lift gravel springs. If you do want to go lower 25-40 lowering will work but you are taking away from ride the lower you go.
Top wishbone bushes are a must in poly - the rest is ok in rubber
Steering make sure all teh ball joints are good and free and teh same with teh steering links. Early cars use a bearing in the idler arm as later cars use a rubber bush. The new bushes fall aprt very quickly these days but you can upgrade with https://www.classicswede.co.uk/Steer..._15830341.aspx

For comfort and ride I would not fit thicker anti roll bars
Dampers Protech's are very good for ride, Bilsteins tend to be very harsh as are KYB's

I am probably not going to lower the car. Luckily the previous owner had replaced the steering links within the last year. I've got ball joints and bushings ordered. Still have yet to make a decision on shocks. The existing ones are still good but I feel that in a few years they will be worn out.

Probably going to try widening the stock wheels so I can fit comfortably 185 or 195 width tire.

MikeJr. has a lightly used set of 5½" wheels with 195 tires that use the stock hub caps for sale.

Easy to say hard to do without screwing up the offset.

Might be easier to have 700 steel barrels welded onto your stock centers by a qualified wheel shop.

That is what I mean. I definitely won't risk doing it myself. I don't have the equipment to do it right.

You'll buy MikeJr's wheels pronto like the bunny when you get the quote including powder coating and tires.

Besides which Stockton wheels is gone now.

I have poly bushings all around and will go back to rubber for the trailing arm big end. I don't like the harshness and wheel hop. maybe that will help. Right now I am running the VP autoparts lowering springs and they might be a little too low. there is not hardly any clearance on the bump stops. Maybe add a spacer, I don't know.

You're supposed to cut the bump stops down when installing lowering springs.

good point. I imagine cutting it too far would defeat it's purpose. What would be a good amount to cut off.

I usually cut them in half with the IPD springs that lower the car ~1". You may need to cut more or use a short poly bump stop if you're lower than that.
