Roll center ball joint spacers and how they relate to ride height.
Hey-O.
So months back i purchased Wise fab spindles as part of a reason to convert to 5x114.5 and sti hubs.
The front spindles have a built in 50mm roll center correction. What a roll center spacer does is space out the lower ball joint farther away from the center of the hub bearing. I won't get into geometry stuff...you can search, etc.
Well, the front shocks are mounted to the lower control arm, when you space the ball joint away from the hub the effective ride height of the vehicle drops.
So, options are to lengthen the shocks or make a new lower bracket. I opted for a lower bracket. I had a local fab shop make some spacers for me to play with. One was 5/8in offset, one was 1in offset. I ended up using the 1inch offset one to get back to the 4.25nch original ride height. So, I think, for every 1inch of shock length you get approx 1.5 inchs of ride height, maybe a less, I didn't make a scientific model or measurement. 20240901_183118.jpg20240901_183142.jpg
