Hey guys, so this is an ongoing project that I’ve been doing, and what brought me to take this on was the low front end support we have.
We have awesome front upper control arms (FUCA) by SPL and voodoo, and then if we want to go further with steering it’s all full on conversions; Part Shop Max, Wisefab, Voodoo.
T-demand offers an adjustable FUCA, along with a fully adjustable - bolt on- lower control arm (LCA) but at a very expensive cost.
There’s also some DIY mods out there as well but don’t do enough, and doesn’t solve the ackerman issue when getting that 1-2 more degrees.
*Cue in my Saisei knuckles*
"Saisei" is Japanese for "rebirth", rebirth knuckle if you will, and I will be doing a few variations.
Version 1-3 will be mainly for grip setups / stance culture for tower clearance for those super low ride heights.
Version 4 will incorporate an overhaul of the outer tie rod (OTR) point, and will test a few variations before the final result. More than likely an offset spacer may be necessary to reduce the ackerman. (Part shop max, also just announced their upcoming steering rack mount, which pushes the rack forward, eliminating the need of offset spacers)
However the purpose of my project is to obtain better angle, with good ackerman, at less cost with the least parts changed.
The jig will work on the knuckles for the following chassis
By factory the upper arm is angled upward in comparison to the lower arm. At stock ride height, suspension travel and camber change is fine, but when lowered these values change and can lead to unwanted characteristics depending on your goals.
• Shortened 30mm bringing the upper and lower arms in parallel, and away from hitting the chassis.
• TIG welded and gusseted on three sides to ensure strength to out-stand the abuse track driving: grip and drift.
• Optional static camber / KPI setting.
V1 - 30mm shortened (~ 1* camber correction)
V2 - 30mm shortened (~ .5* camber correction & scrub reduction)
V3 - 30mm shortened (neutral camber & further scrub reduction)
Started off with a couple of cores to ensure consistency
Super overkill jigs to prevent any deformation
Sectioned and prepped for TIG welding. Shown here is V1.0

I will be posting in here as well, but at lower volume. I will also be offering these for sale in the forum once AK responds to me about the “vender license”
