1970 Hot Wheels Tune-Up Tower: Introduction

When they first rolled out, Hot Wheels were billed as the Fastest Metal Cars in the World. How right Mattel was. As kids, we loved the speed and would run our cars as hard as we could all day long. The result, more than a few of our vehicles ended up looking like this.

All that wear and tear meant the axles got bent and the wheel bearings filled up with dust and debris. The result? Our blazing fast Hot Wheels cars began slowing down.

Thankfully, Mattel provided a solution for us in 1970. The Tune Up Tower allowed us to test our cars for drift and wheel speed.

The problem with most Tune-Up Towers today is they are used, missing parts and in need of repair. I have several Tune-Up Towers and none of them work properly.

So, I am going to explore the inner workings of these machines and see if I can get some of them to work like they did in 1970. That way, when my ’68 Custom Corvette gets towed in…

1970 Hot Wheels Road Trials Set

The 1970 Hot Wheels Rod Runner Speedway Set lets you run “lap after lap” action on an oval using a single-lane rod runner.  To take things one step further, Mattel added a Tune-Up Tower and produced the Hot Wheels Road Trials Set.

This set includes 12 1/2 feet of orange track, 8 joiners, 2 full curves, 1 lane merger, 1 single-lane rod runner and 1 tune-up tower with 1 wheel wrench.

The Tune-Up Tower is a 3 level structure with parking on the first 2 levels and a Dyno-Meter on the top floor.  This rolling treadmill is activated by a white switch on the tower roof.  The Dyno-Meter measures spinning wheel resistence and wheel alignment.  If a wheel is bent to the left then the car drifts to the left.  It makes sense that a car pushing into the sidewall of the track will encounter greater friction and run slower.

A wheel wrench is provided that allows you to bend the axle so that tire alignment is more true.

The result should be a faster car.  Mattel lets you “Road Trial” your mechanical fix by supplying an orange ramp off the top level for access to the track oval below which is powered by a single-lane rod runner.

If the car’s performance is still off you can bring it back in for another “tune-up”.  If it runs fast and straight you can come in and park or stay out and “race ’em nonstop!”.

The Tune-Up Tower also has an elevator operated by a second white switch that will take your car to any of the 3 levels.

So there you have it.  The 1970 Hot Wheels Road Trials Set with Tune-Up Tower and single-lane Rod Runner.

It’s still fast.  Still fun.
