Re: Please post your ride heights with coil overs
I looked at the link to the page in the factory service manual. I also have read somewhere, possible DALI, about the 16mm rake stagger. However, I don't see ANYTHING in the factory service manual about staggering it 16mm. Is that just a tried trued and reccommended stagger by dali?
if you look at the raw numbers and put the difference between front and rear by the book, the difference in stagger varies from 33mm to 53mm if you set up the car to stock ride height with coil overs. So according to the book, 16mm is NOT enough rake.
Nice catch. When I posted I was in a big hurry to a Lions meeting and wasn't thinking straight. The rake should not be 16mm at all. My mistake. SHAME.:redface:
The rake in the book for the 15-16 wheel setup
is 53 to 33 mm difference from from to rear. You are right.
The Dali setup range would be 37 to 17mm range of rake. Since you are starting with a entirely adjustable setup, and not the stock one which could have a broader and uncontrolled range, I usually go with 28-30mm of rake, using the manual measuring points, and I adjust the coil overs just low enough to get to the outside(negative) limit of the camber specs in the rear.
At that setting, the front falls in the camber spec as well, but a little more to the center of the range.
This makes the car handle great, to me looks great, gets the front and more important, rear camber in spec which greatly reduces a NSX problem: inside rear tire wear. Get the car in spec on camber, caster and proper toe (especially important on this car the front to rear bias) and the car feels like it is on rails.
At one time,I had my car so lowered the rear was -3.5 camber. Except for when under very hard cornering the rear tire patch is very small at -3.5, kind of like a 3" bicycle tire. Looks cool, and on track day, on a tight course, it might be OK but otherwise it isn't putting the rubber on the road.
IMO setting the rake/ride height as I outlined and getting the rest of the numbers in spec feels much better all around. Try it and I bet you'll agree.
Thanks again for pointing my blunder out.
