Upper Control Arm mod (slotted bolt holes) for Added Camber?

[n_tensetuning]

Hi guys

Just curious how many out there have slotted the 4 bolt holes in the upper control arm to allow for added camber Tuning?

Seems like a wise thing to do for added grip and for matching rear wheel negative camber.

It seems a few Delorean outlets already incorporated this mod into their own designs:

Heck, Vw's have had for years slotted hole ball joints in addition to matching slotted hole control arms.

Perhaps doing both would be even more advantageous for Deloreans?

It looks like this shouldn't be a problem at all doing this mod on the stock upper control arms. There's an additional plate/metal stitch welded on top for added strength.

Thanks

Now this would be a great fabricated version of our upper control arm

It sure would!

Ours use camber plates that are not pictured. Not as simply as just slotting the holes. The ball joint will move under load only bolted in place.

I built a set of UCAs that allow for camber and caster adjustment. I made them about an Inch wider than the originals so I could install shims between them and the shock towers.
I also slotted the holes for the upper ball joints, but installed a "Keeper" plate to make sure they would never slide out of adjustment.

Uses all stock bushings and ball joints.

Josh, those UCA's with adjustable camber & caster are awesome!

I'm running KW coilovers + billet LCA's myself.

Delorean Industries, thanks for chiming in too.

I understand now about an additional support plate being necessary to withstand impact forces.

I've been looking at having the UCA's modified by Reid Performance..... good value

Yeah, that modification for 150.00 is asking for a failure. I would email the company and ask to speak with their in house engineering team about that solution.

That is a serious upper arm. I like it. Are you using the extra width to achieve a caster adjustment? This is something we are incorporating into REV E stainless frames. We have engineered an adjustable upper point that can be reached from inside the tower via the extra clearance achieved running a coil-over spring instead of a bulky stock unit.

You could have also just bolted shims to that upper angle ball joint plate for a really solid mounting.

Yeah it is a bit overbuilt and certainly bulky and not a nice shiny SS piece like yours. But it will do the trick for me.

The extra width is indeed how I am adjusting caster. I am currently just using washers to space it out swap them front to back to change the caster, but I hate stacking washers it is very amateur.

Im glad your working that into the frame, its going to be a nice selling feature to tout fully adjustable front suspension.
