Rear Weight for Low Grip

[FrogPrince82]

I've been looking at the rear weights that you can get from Tresrey and RDRP:-

I get the idea that they are to improve the weight balance of the car while in MM format, to give more of the drivability of the RM without going the whole hog and changing the gearbox around. This is for low grip track surfaces so should benefit when driving on polished wood floors etc.

Plus, as the grip levels improve, you can always remove the weight quicker than you could change the chassis layout

I was wondering if anyone has used either of these? If they found them to be an advantage or useful tuning aid?

I ask because the Tresrey adds 24g and the RDRP is 50g which seems a big difference in options (although the Tresrey is more expensive for less weight ) and I'm not really wanting to fork out cash for the wrong one e.g find that the Tresrey makes almost no difference, or , that the RDRP makes too much of a change too far

Any help would be appreciated!

P.S. I've only been driving for 3months now so pretty much everything is new still
