i have all the weights made buy RDRP, the RR toe block and the RF toe block and the rear weight that hangs over the back.
i always have the RF weight on my car no matter what surface i race on, as for dirt i normally just used the RR block as it only weights 18 grams ( i think), the RDRP rear weight is 50 grams and tresray is 24 grams.
i also have the tresray weight but i preffere to use the RDRP battery stop weight which is also 24 grams but weight is in the car not out the back
hope this helps
