I've gotten my Tamiya Wolf WR1 to behave pretty well on the track. The softer T-Bar (white) made a HUGE difference. The stock tires are not as sticky as the TCS type, but Tamiya doesn't offer TCS versions of these tires and our track mandates only "Tamiya" can be used. So, I dope them up with Paragon and as long as I stay out of the marbles, I've got pretty good traction.
The tires are taller than the standard modern version tires as well. With the stock out-of-the-box gearing, that means that my top speed is faster than a stock F104 like the F60, but the initial punch isn't there as much obviously. I need a pinion smaller than what comes with the kit (14?) and I've not found those yet.
Still, all in all, I really like this car. Its old school, but so am I. I remember the Wolf being THE car in F1 in 1978/79. It won its very first debut race! Jody Scheckter was the driver, but eventually Bobby Rahal drove it too.
I have purchased one of the McAllister Indy Car bodies which will be perfect for the F104W and these tires. Hope to get it painted soon. I'll still run the Wolf as the Wolf, but it will be neat to have an alternate body to use.
