I do have the TRG front uprights, plastic spacer was in package with uprights and I have 4 Tamiya F104 spacers available. With TRG plastic spacer and one Tamiya silver spacer it looks OK but I will test it next weekend on the track.
I need to finish the car first but references from the fellow racers are good. There should be less tirewear than Tamiya F104 foams...hope I will know more in a week.
I will test my F103 Rapide tomorrow with Xceeds. Which compounds do you have? Someone tell me Xceed fronts make the car to oversteer, donīt know personally have to test this.
