I'm using about 30mm up travel (measured at the bottom of the axle) is that ok or should I use less.
I'd like to adjust the rear bump steer so the wheels toe in as the rear lifts to get more rear grip at corner entry. Am I right in think I'll need more shims on the outer st24 to achieve this and possibly make the problem worse.
With Spr02h do they touch am17l/r for up the travel stop or do you still use the screws in p12?
I don't have the RFG, so I'm not sure how that may impact shimming and clearances unfortunately. But in general I don't really measure my upstop, I simply make sure it doesn't allow the SPR02 to go up so far all the stress is on the SPR02 and AM17.
I have not tried going that direction in rear bump steer, so I can't comment on that setting specifically, but I would use a setup station to make sure I'm shimming the right direction. Check the toe at standard ride height, then press the chassis down/lift it up and check the toe again.
The SPR02H still touches the AM17 just like the original units, but I do still use my upstop screws just to spread the stress of the impact if the suspension goes up that high.
Edit; I'm curious what your opinion/insight is on the RFG and what surfaces you have tried it on. I have been considering getting one but on the fence. Haven't really seen a whole lot of feedback on it.
