Default Steering Feel RSR Downs

Anyone else on RSR downs and 19” wheels? I feel quite a bit of steering feel difference. The steering wheel tends to turn right or left on bumps (even small ones). Having bad roads here in Alberta makes it feel even worse.

Wondering if it’s expected or the wheels are either bent or not balanced properly.

ive gotten an alignment already after I installed the springs.

Doesn't happen to me, I am on stock wheels though. I also have the RCF/GSF bushings which are stiffer which probably help keep the car in line to avoid that movement

Hm thats interesting. Im going to look into getting those bushings.
I might just put the stock wheels back to see how it feels

Without actually driving your car, what you feel may be normal.
You're very close to describing "bump steer".
Considering that lowering the vehicle reduced the stroke of the suspension when you go over bumps, combined with the fact that you likely have wider rims/tires...hence what you're feeling could be very normal.
I would consider the RCF/GSF bushings still...you my find they will improve the situation.

Gotcha. That makes sense. The new rims/tires are much wider than stock. Hopefully putting in bushings will help
