F103 tyre setup
 

Hi all. Just picked up what was sold to me as a f103. But i believe to be an f103rm after some research. Plan on racing this at my local club on a 13.5 1s setup. We race on a carpet with low/med grip on foam tyres in TC, mini and gt/lmp.

My usual setup for tc is 32shore rear 35shore front.
Lmp 30shore rear 32shore front.

What would people reccomend for f103? Car came with set of rubber and foam wheels (foams look new) unknown compounds but rubber fronts have almost no drag running thumb across them, rears feel grippier. Foams feel very hard i would say at a guess 37 rear 42 front (official tamiya foam as has two stars on sidewall?)

I can run either foam or rubber but nobody runs rubber in touring car due to lack of grip even on sorex 28 with additive.

Thanks

foam for f1
 

hi colin
at our club we found it increasingly difficult to find foams to fit f1 cars i thinkwe found the tamiya f103 have a different set up to later modern f1 cars like xray,serpent yokomo and associated most now run rubber with additive
the only other option is too buy your own donuts mount and trim your own I have a scruffy tamiya f1 you can have if you need spares can send pics

If you can run foams them there no point even considering rubber tyres as is easier to get hold of F103 foams than rubber tyres that will work.

My base setup for F103 on carpet is 30 shore rears with 37 shore fronts, with 35 and 40 shore fronts for tuning. Tamiya don't list shore ratings, their 53129 HBR soft rear and 84096 HBR medium front are a good combination. Try any of the usual F1 specialists, RacecraftRC, The Border, or RC Mart

Thanks both thats a big help. PM on the way regarding the spares car!

Thanks
