Front motored Alfa TZ2

[Audi1]

Alfas have always been one of my favorite cars. Today I purchased a Fly Alfa TZ2; I love the lines of that car. I knew it was a front motored car when I purchased it and I knew that it had independent front axle stubs. What I didn't know was how wobbly those front axle stubs would be.

I plan to build this car out and run it in the IPS proxy. I now know that one of the things that I'll have to do is to deal with is the front axle. Since I'm going to run it as a front-motored car I can't put in a solid front axle and the rules for this proxy don't allow a solid front axle anyway.

So, what's the best way to deal with this front axle stub slop? Are there any standard fixes that people have used over the years? I could use some advice; thanks.

You can try this too.









Using K&S 1/8 inch brass tubing, measure and cut the tubing to the desired length. Once you cut it, make sure the tubing is free of any excess flash from the cut. Next, press the tubing inside the axle mount. You can do this by hand but it can be a very tight fit. I used a small needle nose pliers to set my tubing in place.





Now simply re-install the wheel onto the axle. Test fit the wheel first to make sure it is spinning freely and then you can remove it if you wish and add a small drop of adhesive to the wheel to make sure it stays in place. You will now find that virtually all the excess slop is removed and you have a much more stable front end.

Hey Audi, I just bought one for, the same reason, special series of front motored cars.
So your post is timely as are the answers.mI'm still waiting for mine in the mail, so I will keep watching here to see what you do and how it works.
All, the best

Thanks goosenapper and Harry. I like the brass bushing within the existing plastic axle holder. I plan to run CBD wheels, so I'll be interested in being able to get the front wheels on/off, as needed. Is the standard Fly axle stub 3/32"? If it is, then I should be fine with it. Otherwise, I'll cut some 3/32" music wire to size and solder a washer to the back to help hold it in place. I plan to tune the front ride height by truing the fronts, rather than by adjusting the stubs up and down.

We'll see how it goes.

PS - where can I get an M2 tap?

It looks like that turned out very well. I didn't think you'd have the clearance between the stubs and motor for that kind of set-up, but it worked.

Well done! :handgestures-thumbup:

Nice job Allan.
Very precise fitting of the axles in regard to the motor.
Mine is the blue one so I will try the same thing.
Thanks

Nice work Allan.
I guess I will get to drive the car about June this year.

Let's hope the wheels are still on by the time you see it, John! :lol:

Great job. Looks like you have it about as good as it can get. Good luck in the race.

Not sure where I'd be with any of my cars now, if it wasn't for the help I get from Toronto. Thanks, Chris.

Really nice build! I was wondering, what are the wheels that you used? Are they SCC? Can you share the size of the wheels? I have one of these and you've inspired me! :text-bravo:
