From what I have weight it is 3.4g lighter than stock parts.
Around 8% weight savings of a critical rotating mass
On top of less rolling resistance.
I haven't seen a HUGE performance gain but my AVG end voltage is lower.
Thanks to RCSS for a top quality manufacturing product.
Looking forward to more testing .

Just received the gears last week. They went into the diff and transmission of my SC 6.1 with out any problems. Have run one Saturday race, three qualifiers and a main, of 17.5 with them so far and have had no issues. They appear well enough made. Looks like RCSS took stock Associated gears and machined the down. I do not expect any problem running them in the stock short course class.
