Trg-103 rims/tires will bolt right on 109.
Watch out for the trg superion tires as they are VERY soft and really only good for a qual round when the track is loose.
Front f104 bearings are 5x10mm so if the Ride rims are true 104 wheels you would need 4 of them,
I would not bother with the soft fronts (waaay to soft for the front of an f1 car).
You might want to look around for different inserts too as they make a major difference in the way the rubber tires work
(Some of us have been cutting out old tc inserts and gluing them together).
The trg inserts come split and need to be glued together but because the foam is so soft it's hard to glue them without being able to feel the glue line through the tire.
I prefer the one piece Ride inserts.
If I remember correctly Ride B's are med.Not sure on A and S.
Inzane should know.
