The recent sticky indicates the front lift doesn't allow ride height adjustment in the front--only the back. Assuming that's correct, does that mean a car with the lift can't be corner weighted?

 

You would still be able to do corner weighting but with less adjustment range.

 

Please explain!

 

When you corner weight a car, you adjust the car so that (as far as possible) both wheels on the same axle (front or rear) carry the same weight; and so that the cross weights (LF+RR versus RF+LR) are also as close as possible.

If the front is not adjustable, then you use the adjustments at the back to achieve these goals at both the front and rear at the same time.

But if you are serious about corner weighting (like any real track car should) you will want the front to be adjustable so that if the chassis gets tweaked; the car can still be corner weighted.

 

Also if you are corner weighting optimizing handling you simply lower the car down on any nose lift. Then put gas into the tank to your optimal fill level then put your weight into the drivers seat or actually sit in the car then adjust spring perches until the cross weights are as close to equal as is possible.
‘That’s optimized as far as cross weights and handling for a road course.

 

Ride height adjustment in one corner affects weight on all 4 corners.

 

I knew I shouldn't have responded first. Say you have less weight on the right rear than the left rear. So you raise the right rear and transfer weight to that wheel from the left front. Trust me, it really works that way. The idea is to keep moving weight around until the left weights are equal to the right weights, or at least, the "cross weights" (left front plus right rear and right front and left rear) are close to equal. This should be accomplished with the driver's weight on board, ideally. Most street cars have imbalances, especially when the driver is included. If only one end of the car is ride height adjustable, you might have more difficulty getting weights equal while maintaining desired ride height. In the previous mentioned situation where you're trying to transfer weight to the right rear, you could do that by lowering the left front if you have that adjustment available. Since most posts on the subject of ride height adjustment seem to be primarily interested in lowering the car I can see where some owners would be loathe to raise a corner simply because it doesn't look cool. The whole point of this is to get the car handling equally well in left and right corners.

But other posts I've read indicate that the front will be adjustable regardless of options, so don't worry.

 

From the horses mouth at Carlisle , Harlan said ALL C8 have 20 mm adjustments in each corner for you to corner weight or drop ride height !

 

stand corrected
Front Lift = NO adjustable front spring seats

 

I am not sold on the statement that the front ride height/ where to adjust for corner weighting will not be adjustable if the front lift option is spec'd.

Jake in Post # 9 indicates is adjustable.

When will a service manual leak?

 

See the new sticky thread. Harlan was mistaken..


If youre counting on C8Jake for information, don't

 

Note only Z51 optioned cars have the adjustable spring perches. Not standard suspension cars.
