Thread: Four Link Specifics Required

Tweet

I much prefer the urethene bushed ends on the street. The heim joints are a bit much for the street, hard to keep clean and lubed and just plain noisy and rattly. IMO best left for the drag cars.

Ladder bars work fine on the street, just subject to binding up a bit more then a 4 link. I've ran them on the street, just have to remember what you have on the rear when you start playing on a curvy road! They will tend to build a bit of push into the front end if you get back on the power a bit soon...

I don't have any pics that show the 32s panhard bar.
It goes from left inside frame rail to as far to the right side of the rear axle it could go and is in front of the rear axle.
Since it has to go forward a touch compared to some cars the axle end is mounted much like the bottom end of a coilover with a coilover mount upside down and a 1" bushing to space it out like the bottom of a coilover.

The 31 on 32 rails car is a roadster as well.
It runs a transverse leaf spring on the rear and due to 'packaging' problems the panhard is behind the rear axle and shorter than I like, but it should work ok.
If you look close at the pic you'll see the left side bushing welded into the rear crossmember and a short bit of the panhard bar.

You may be wondering why the panhard since it has a transverse leaf spring.
We had a long discussion on the HAMB a couple years back and since the car was originally slated to be a dry lakes car a panhard would add a little steering accuracy at speed since the rear spring would swing on the shackles a bit.
A lot of guys run sans panhard on the street with a transverse sprung car, but since I make these at home it didn't take long to knock one out.

This pic shows how the rear axle was set up.

The 4 link you see is a ChrisAlstonChassisworks kit.

A drag racing piece made from 1 1/4" OD tubing which is overkill for a street car, but it should work ok.
Couple of nice things about the kit is, it's adjustable for instant center and all that, but right now the links are parallel.
First thing up after the car is running - and probably smoking those skinny tires is to bring the top bar down one notch in front and perhaps the bottom bar up one notch. (Both roadsters run torquey 462" Buicks.)
Shouldn't be a problem on the street adjusted like that.

If you get a pencil and a string, swing the arcs and measure the difference it isn't very much at all . . . which means the pinion angle changes only a very minor degree and is not the end of the world like some of the evangelical style preaching guys do about differing arcs.

Another nice thing about the ChrisAlston links is the style of polyurethane bushing they use.
It looks like a cross between a Heim joint and a street rod poly bushing.
They have a website and there should be a pic to show that.
I believe they make that type bushing in smaller sizes as well.

The 32 does pretty good far as traction goes, large and soft rear tires with an 8"+ tread.
Probably better than the hard slicks from back in the day.

Sorry about the pics.
All the information is there on the word processing program I use as well as on the edit screen here at CHR.

I posted an article yesterday and they all came through ok.
