Ball Joint Extenders.....thoughts?

Cruising thief bay and found these....

Seems like they would fit Audi's with 19mm ball joints and they can make 17mm by request. Probably help keep things in proper alignment spec for lowered vehicles. Anyone using these or have opinions on them?

Stiglet on here used these on his CQ... in conclusion i think he said they worked in principal but were not really man enough for the load from the weight of the coupe, and also IIRC they fouled the brake disc, even with OEM twin pots. A bit of a bodge job of resetting the roll centre.

My plan is to swap the forged wishbones Left to right and invert them, so the ball joint fits on the top of the wishbones not underneath, should yield about an extra 15mm on the ball joints effective position. Yet to be tested......

Good idea but can be tight clearance when fitting and I'm not convinced about safety. Search for threads by Anton and Stiglet.

I have these exact ones on my mk2 golf and they are good quality and do help with bringing the lower arms back to level.

You need to extend track rod as well, to avoid pump steer with this kind of mod.

hmm seems counter productive solving one issue and causing the others

maybe not the right solution to the issue, there must be a better one?

No, this is proper way, You just need to extend the outer joint of the track rod the same length You extend the lower ball joint.

Would there be demand for these? I could easily have them available. Would be a kit with two balljoint extenders and two track rod end kits with adjustable length to replace the original joint completely with a motorsport uniball.

Proper way indeed, but I wouldn't be too worried about the bump steer, As Audi track rods are half a meter long, so 40-50mm won't do a massive change.

E: A small geometrical study: Unfortunately I don't have the real dimensions of audi suspension geometry, but if we estimate that the track rod is 500mm long and the steering arm in the column 200mm, every 50mm of track rod moving up/down equals about 2,5mm horizontal movement which equals about 0,7 degrees turning the wheels.

E2: Silly me. The change is not linear, it follows a sin-graph. So a 100mm change wouldbe 10mm horizontal -> ~3degrees turning the wheels.
