I am now using Tifosi engines, Donelots tyres and Elves fuel, is this a good choice?
My engines shortlist: Tifosi, Rednote, Toymotor (Rednote was consistent but too slow, Toymotor was fast but not consistent, Tifosi is okay)
My tyres shortlist: Donelots, Bridgstone (Donelots seems to give me the best qualifying times)
My fuels shortlist: Beep, Elves, Chavon (Elves has the best performance, and I don't think weight matters too much, so efficiency should not be a big factor, right?)
Please tell me which suppliers I should pick.
That'll work well, just experiment. I've used Tifosi, Rednote, Murk and Cosurworthit for more than 5 races each. Just experiment. Though Subtotal should be on fuel consideration :)
