corner balancing - adjust preload or shock length?
I'm reading up on corner balancing, and one thing that isn't clear is the preferred way to adjust the cross corner weights. I haven't found any mention of it in any of the articles that I've found. I have Ohlins R&T, so I could do either preload or shock length. My general feeling is that shock length is preferred so that as target cross corner weight is approach, wheel travel should equalize as well.

Yeah, read the same thing. I always thought it was strictly ride height adjustments. Changing pre-load, to me, affects compression / rebound & would be concerned about a corner to corner imbalance.
Its, no doubt to me, art & science combined. Dont know what you track involvement is, but corner balancing is only for those at the higher end of track work IMHO

That's a lot of toil / labor if the EvO is not going to the track.
Have you seen a corner balanced car? You can likely see significant fender gaps diff from Left to Right
Anyway, I can appreciate your interest in wanting to know more about the process

Its really not a lot of work to CW a car unless it has some rusted coilovers that don't spin very easy.

not always true. On something like a FWD Civic, yes those can get tricky to CW and might have a slight fender gap difference. But most evos I've done are pretty dang close (within 1/4inch at most).

MRfred doesnt even track the car so I was mainly expressing my opinion as to why do the CW if its just a streeter

shock heights are ideal as I understand it.
that said, it shouldn't "matter" if the spring is always compressed more than what you add preload for. this is probably the case in the front but not always in the rear (if you lift the rear). i.e., you can add 1/2" of preload but if the spring is always compressed 2" then does it matter? the front's never going to come off the ground while racing.

I'd recommend running no preload. you remove the droop travel and like you said, will start lifting a wheel.
put just enough preload on the spring to hold it in place. then do all adjusting with the lower (moving entire shock body up/down).

Typically, to get good CB on the evo, the passenger front, and driver rear coilovers need to be a few turns longer. You don't use preload for corner balancing. Preload isn't really something I've seen the need to use on the Evo. It's usually used to attain ride height when you want to run a softer spring, but most coilovers are ride height adjustable.

I get a CB and alignment at the same time when a new setup goes on. So it's hard to say what I "feel" because the car just got new coilovers, new alignment, and corner balance.
