White line KCA434 front lower control arm bushings
 

Anyone installed these yet? The front lca bushing is a odd spherical bushing? that my mechanic says is prone to early failure in other cars he has seen. Figure these should improve the steering response as well.

Curious for feedback from anyone who is running them.

I'm running them but no track days on it yet. Only one autox session. I have all of the Whiteline bushings on and their sway bars as well. I didn't really notice much if anything with those bushings, but like I said I haven't been to the track. I have noticed a positive difference with their rear sub-frame inserts, differential inserts, and trans mount. My build thread has info on what I've done to my car if curious. I'm thinking those bushings wouldn't yield too much of a difference since the stock ones were brand new. If the stock ones were old and used up then I'm guessing I'd notice more of a difference with those bushings. Regardless my car feels very planted, stiff, and tight, insert other similar adjectives here... :)

I've been running the bushings on my car for nearly 6 months. 12000+ miles, a dozen or more AutoX event days, NO issues.

I have them, feel great. I changed them with the WL castor bushings, rear upper control arm bushings and steering rack bushings.. so all a contributing factors for the better feel. But as others have said, the difference won't be so great as you arecoming from fresh factory bushings that have yet to break in.

I'm getting ready to install the KCA434's on the front LCAs later this week (rented a bushing press kit) and I'm curious, for those that installed them, does the urethane bushing rotate in the stainless housing? (I haven't received them yet).

I know you need to orient the dimples towards the inside of the car per the whiteline instructions but I'm worried about the precision of the alignment of the dimples.

I would also like an answer to this question.

No ! I was try to adjust it but couldn't , not without taken the arm off. But mine is super pro , look very similar to whilteline .
