Default HPI F1- old version


Have a friend with the older version /orginal HPI F1. He would like to run it but needs to install rubber tires to run with the newer cars. Is there some adaptors for the front and rear rims to make this happen? I need part numbers so I can tell him what he needs. Thanks

So I guess unlike Tamiya there are no conversions?

THe HPI Super F1 uses wheels and tires from the 1/10 pan cars like Jaco... if there are any rubber tires that replace those that you can find, then you'll be all set

I have a Super F1 myself, but I've never thought about a rubber tire option...

To run rubbers the wheels will have to be changed to f1 wheels from the pan car wheels the super F1 runs.

Front wheels are easy as the 5/16" bearings will fit in F1 wheels for the F103, with a little bit of play as the HPI bearings are a little undersize. A wipe of cyano or a layer of tape in the wheel bearing seats can take up the play.

For the rear to fit F1 wheels it will need the whole rear axle replaced with an F1 diff and axle, and the smaller F1 tyres could give you a problem with ground clearance so you might end up replacing the rear pod with the 3Racing F109 motor mounts so you can use the HPI top plate on the pod.



The other way, which is unlikely to go down well with the other drivers, is to just bolt on a set of BSR cap tires, designed for oval racing so lower profile, wider tread and more grip than F1 tyres.

Thank You - the third idea won't work. Any more suggestions will be appreciated. I'll past the others to my friend.

The new Hpi F 10 car also uses a 1/4" axle. You could get the stock axle and use Hpi rear tires, or they also sell an option axle to use Tamiya tires.
