818R Suspension and the Steering Rack

[Rasmus]

I asked David to move this thread to the 818R Discussion sub forum. Thanks man.

I would love to see this discussion continued.

The move is not 25mm as in the first post, but 2 7/16" (62mm). It looks like a lot of twist on the cast ear of the upright. Thinking about a bumpy corner on race rubber makes me nervous. A failure here could be catastrophic at speed.

I hear what you are saying. You have to remember the car is much, much lighter than a stock WRX. Plus, all the "Force" is not on the steering knuckle. If all the "Force" was on the steering knuckle, we would not be able to turn the car very easily.

The majority will be on the LCA ball joint and upright (notice the thick steel and welds).

That being said, the 2 7/16" spacer does act like a lever. Getting hit "just right" I imagine the cast knuckle steering arm would be the first thing to go, or we would just get the wheel stripped from our hands. No different than other race cars out there with cast parts.

I'm not too worried since the factory 818R has been on the track alot (bumpy tracks), and actually went into a Tire wall (Journalist).
