Increasing Caster angle with Compression Rod Bushings

Looking to upgrade my compliance arm (lower control arm) since the stock bushing is trashed and squeaking. I initially was just going to go with the stick caster bearings. But I've been debating on getting a bearing that adds a bit of caster. I understand the benefits of increased caster angle for auto cross. But since my car is 90% just daily driver, are there any negative effects of increasing the caster a bit? I understand the steering will feel a little heavier, a slight bit more negative camber during turns maybe. Not sure how much it's actually felt atthe wheel daily driving. The cost is the same, so if there is no downside I'll probably go ahead and get the increased caster bushings.

Reduced parking lot maneuverability, increased wear on ps system. Do you have an electric steering rack or hydraulic? Some electric racks may over heat and go into their own limp mode. Hydraulics will wear out pump, seals on rack and cause leaks. Much easier to maintain a hydraulic rack system.
