Alright, Integra people, here’s something I keep coming back to: when we’re talking aftermarket knuckles, should we really care most about break strength, or is it time to focus on stuff like corrected suspension geometry, yield strength, load path, and how the suspension actually behaves on the street or track?

For those of us running lowered Integras, we know a part doesn’t have to snap in half to mess things up. If it bends or tweaks the suspension into weird angles, suddenly your camber goes wonky, alignment gets sketchy, ball joints wear out, UCA clearance gets tight, axles get stressed, and the car just doesn’t feel right. Has anyone else run into this?

So here’s the real question: would a shortened, well-designed knuckle made from something like 7075-T6 billet aluminum actually work better than just beefing up the stock-style knuckle? Has anyone measured the difference in real-world use?

Curious what you all have seen if you’ve tested different knuckle setups on lowered or track-driven Integras. What worked, what didn’t, and what surprised you?

3D Printed design with 1.5\" Roll Center Correction and Upper/ Lower Ball Joint Angle Correction

Front LCA Aligned to 0.00 Degrees

Front Upper Ball Joint Aligned to 0.00 Degrees

This Measurement was taken to find the difference between UCA/ LCA to correct the geometry between the 2 Control Arms.

I chose this LHD EG Civic to test fit my 3D-designed front knuckles.

One of the most common requests I hear from enthusiasts is for proper roll center correction, improved upper control arm ball joint geometry, and an overall stronger knuckle design. That is exactly what I set out to address with this setup.

This is a 3-piece design with a modified steering arm to help combat bump steer on lowered cars. The upper and lower ball joint areas have both been dropped 1.5 inches to improve handling characteristics and bring the suspension geometry into a better operating range.

After test fitting and making a few corrections, I am now starting to produce these in billet.

Stronger design, improved geometry, roll center correction, and bump steer correction built specifically for the EG Civic platform.
