The Track Magic was an awesome American made chassis in it’s time, along with the newer Margay chassis, in my opinion
But sadly went out of business, and support or replacement parts would be a bit of an issue, but not impossible, as there are lots of new and used parts available out there
The only issue I had with them was the primitive front and rear brake system, very old and outdated, I also noticed that Sodi Karts had the same brakes as the Track Magic
I would totally stick with the CRG, and if you want to go newer, then just buy a newer CRG, they are proven winners, and supported almost anywhere, and not to mention parts are readily available almost in any race shop or online store.
That’s just my 2 cents, hope that helps….. Fast Freddy.
