As above , which tire additive are people running indoors on carpet , especially on touring cars ??
I have been using the nosram stuff , it seems ok and fairly common at our local club , and its handy with the applicator dab thingy !!
I've only recently gone back to indoor touring ( still doing 1/10th buggys tho
) and used to use the cs grip , but it was easyer to get the nosram when i returned !!
Last night i ran the nosram in the quallies , and decided to run the schumacher 3.0 additive in the final , i didn't change anything else on the car , but it seemed a bit more consistent ..
btw if it matters , i'm running a xray t4'14 , 13.5t with boost/turbo , and the grip gets pretty good , due to the mini's and supastox running foams etc and on a small - medium size track ..
