Both of my trucks have had the LCAs trimmed for about 26 years between the two of them.
Hundreds of thousands of miles. A lot (a LOT!) of them hard, hard miles.
I like the twisties. (There's some r-e-a-l-l-y good fun roads here!)
At speed. For hours on end. It's nothing to rack up 150 miles or more on a Sunday, just blasting around the mountain backroads.
The outer edges of my front tires wear out before the rest of tire.
I kill shocks.
Off-the-shelf replacement rotors last about 8 months.
I've gotten good at rebuilding the front ends of these trucks.
...and yet, I have never had a problem with the LCAs after they were trimmed.
I kept an eye on them for the first couple of years. No spreading. No cracking. No probs.
They're the least of my concerns when tucking into a freeway entrance ramp at 60mph against a posted 40, coming out at 80+, and still leanin' on the skinny pedal. Trimmed LCAs are not what I'm thinking about at those moments
I'm more focused on that seeing that dip that's going to throw me off my line.
...or into the weeds.
...and gravel. OooOoo. Scary **** when pulling G's.
