Hi all. Has anyone found a supplier/ part number for a shock spring that's compatible with a '19 ES model? I've looked through the forum and found mention of springs that require custom shims and spacers, but no mention of anything directly designed for the T12 ES. Also the spring rates for the ES and non ES appear to be different. According to the Racetech website, I'm looking for something around 21 kg/mm. I've tried calling them as well as e mail on several occasions now with no return response, to the point I've pretty much given up on them.
I'm 6'2, can shuffle her down a FSR faster than she should, and lets just say that when I get on the scale, 225 is still blurry when it goes by.
Thanks!

Racetech used to make one that was a direct drop in without spacers. I purchased one in January 2019 with an 8.5kg spring but I heard they may have discontinued it. The model was RSP 6022085 / RT SK SPR 61.2x56.5x222 8.5kg which is perfect for me (190lbs). So 21 kg/mm would probably be a little stiff :)

Yes and no. I wasn't able to source a stiffer spring, so I designed and made a set of shorter links in the rear suspension. I've had good success with these on other bikes and the T12 is no different. The shorter links raise the rate of the suspension stiffening through its travel, accomplishing a similar goal as a heavier spring. An added bonus of the links is that they raise the back of the bike up and quicken its lazy steering geometry. If I remember correctly, the links are 8mm shorter than stock and raise the bikes rear suspension about 25mm (1 inch).
