Roll centre adjusters

[Deuce Cam]

I agree in theory about the drop vs. rca thickness. However...

I tried mounting T3 rca's on my car with stock length casings, tokico blues, and uncut megan springs (shocks and springs are 'long stroke'). Megan advertises a 1.85" drop with the springs, but it's probably actually closer to 1.25". The t3 rca is 34mm (1.34").

With this setup the rack ends would bind with the suspension completely unloaded. I actually tried bolting the rod end to the knuckle with the rca installed, suspension at full droop, and the tie rods wouldn't reach below the knuckle. It wasn't even close - roughly 1" off. I literally had to compress the damper to bolt the tie rod end to the knuckle with the rca installed. FWIW these were heim joint t3 outer tie rods which utilize a separate bolt where it connects to the knuckle, so it wasn't hampering the process like an integrated stud would on a stock style rod end.

Some will say this doesn't matter because the suspension will never be completely unloaded while driving.

I imagine this problem is somewhat common and people just don't realize. Mainly because most people aren't replacing rod ends when they installed their rca.
