spring spacers, out back spring preload.
Do you have a recommendation?
looks like you have a little too much on the rear , should be 70-85 mm on the rear i believe the rear is a pain in the arse to adjust & forks out for the front , I went a heavier spring in the rear (cause i'm a little fat @ 95kg ) but less pre-load, the rear shock is still not to my liking & it i can't get it right on the next right I'd send it back for another revalve ( still has too much hi-speed dampening & can't get rebound right either )

these 690 have a linkage as you know so they very different to setting up other KTM's with out linkage were the rear sag was 95-110mm , i think that why they are so harsh i have seen photo's of the linkage of the baja prototype all billet linkages look to be a little longer but they are using the 690RR frame ,

as a rule of thump if it pushes wide in the front , the rear may be squating to much & if it is tucking under the rear is to high , but this can be counter acted but adjusting the forks in the triple's up & down , there are SOOOOO many ways and thing 's to change it can be very hard getting the right balance , and that is exactly what it is a balancing act between your riding position the balance of the bike and the terrain the you are riding in ,
