The rubbers are off of the Tamiya Newman Porsche 956. Still got that one too, but this one will run better since it is in tact and just needs some greese and a cleaning, (the chassis break on the 956 is rigged to run though, but have metal brackets supporting the engin on the bottom chassis plate).

The rubber tires used to keep the 12L from spinning back in the day (and ran foam on the front) and remember clocking it around 40-50 MPH on asphalt. I should have some live footage within a week or so even if the Gopro doesnt come in the mail yet.

I am getting a Go Pro nextweek and gona try to mount it to it ( I know it will be slower but still could be cool).

Quick edit sorry, also I got my Newman Porsche from a garage sale and came with two sets of rims, one had the rubber and the other foam. Just remembering now it probably was in 1986-87ish when I bought it for $around 50 bucks so not sure of the correct tires that came with it and such but the rubber ones were a second set and installed from when I bought her. Still got the all the electronics too. I also remeber it going at a nice speed and still go the blue bell black can enduance motor. I will probably put that in the 12L to boot with the Kyosho Highspeed Lemans motor. Sorry for rambling.
