I couldn't find an appropriate thread to add this to, so I'll just dump it here.
With SPC front upper control arms, they severely limit suspension travel as anyone who runs them knows well. After cycling the suspension up without the springs, this becomes especially apparent
And anyone who runs the SPC arms knows all about how they self clearance the shocker tower for you. In an effort to prevent this, we used stiff bump stops (Koni 71.34.42.000.0). Here is a plot:
However, the bump stops didn't come into contact with the shock until after the UCA's hit the shock towers so we had to make some spacers. For now, we're using 0.75" of spacer in the front and 0.70" in the rear, based on the measurements we took. This makes the bump stops come into contact with the shock 0.3" before any contact between the UCA or tire to chassis occurs. These spacers and shims are easily removed and we made several thicknesses so we can fine tune it to whatever we need down to 0.05". So hopefully in the future we can gain some suspension travel back and reduce the spacers significantly.
The spacers are made of delrin (McMaster p/n 8576K29) and the screws are 10-32 (McMaster 92210A307) cut down to size as needed. The holes for the screws were already in the shocks, they just needed to be tapped and happened to be the perfect size for 10-32 without drilling them out. I have both the spacers and shims modeled in SW but haven't made 2D drawings of them yet; once I do that I will post it up so anyone who wants to copy these is able to do so.
