[Fot] Independent Rear Suspension

Tue Mar 5 06:38:27 MST 2024

Remember the test drive at around midnight at the lower RV parking lot after you got the trans installed, after it rained ?

I do. I got there late Thursday night and discovered Friday morning I had destroyed one of my trailer axles.  I managed to find an axle in Topeka.

Only after I was laying under the trailer on Saturday between races putting it in that the spring perches were wrong and I said out loud “ great, now I need a welder,

a torch and a grinder all the time thinking I was pretty screwed. I heard one of the spectators standing next to the car say “ I have all of that, I’ll be right back”.

Sure enough he was in less than an hour. I moved the spring perches where they needed to be and continued on.

Great folks in Topeka.

Ah, The Kastner Cup at Heartland Park.

One of my favorite racing weekends of all time, a real treat.

My first Kastner Cup.

I barely made it to the track. I had stayed up for days straight trying to get my car ready. Upon arrival I was greeted with the warmth and friendship of several the Great Triumph hero’s I had, until then, only read about in the funny pages.

My car broke in the first session.

A spectator, a GT6 guy named Brad brought me a moss covered barn find transmission that we installed under the Kansas moonlight.

The next day I was racing again.

I have this distinct memory of Sam Halkias screaming up behind me in the Catawamba Marina TR6. Looking back through my wink mirror he waved, paused and signaled to me with facial expressions and hand signals that only us auto racers could understand saying “nice job little buddy, here I come; I’m now going to fly by you on your left side”.

We partied, raced, bought an Ambro body and finished our first Kastner Cup there in Heartland Park.

When I got home, there it was, a long and personal email from Kas Kastner…praising me, my dedication, the sound of my car, my driving style, and lap by lap list of how many tenths of second I was improving each lap in a segment of the track where he was taking “splits”.

I couldn’t believe it.

It was the start of what Kas called our “unique kinship”

He sure had a nice way of motivating people.

Godspeed old pals.

Yea that was me.  When I revamp the suspension on it it would lift the rear wheel in very tight corners.  Softened the rear sway one adjustment and all was well.

That black 4A was owned by Dan Forgey and is now owned by Mark Eden.
I have an IRS chassis on my '64 and use a quaife and running LOTS of torque and never break an inside wheel loose but in Colorado we can run the Hoosier R7/SM7 DORT slicks. That has to be factored in.
That said, an IRS rear end will almost always grip better than a live axle with or without a LSD.
Overly stiff rear sway bars is usually the culprit. I run 3/4" on mine. A locker has always been out of the question for me.
