The +2mm weighted hex extender for the Trx4-m weighs in at 7 grams and adds just a smidge of extra wheel offset at +2mm per side or 4mm total for a slightly wider stance. Get a little bit more weight and extension without using a barrel nut.
Installation uses your stock wheel nuts but it is recommended to use locktite on the wheel nut as it may not reach fully into the nylon lock on the nut.
