How low is too low on the rear of an EF? What are the negative effects of being too low? Lets assume that the car isn't bottoming out on the bumpstops.

We lowered our STS Civic Si to gain more rear camber at an event while tuning. I've never had one this low in the past. We have adjustable-camber end-links now, so I could raise the rear ride height up and compesate with the endlink to get the desired camber. The question is if I want/need to raise it up.

My thoughts are more weight on the rear wheels means less weight on the front wheels. However, there has to be something wrong with running to too low.

 

Don't know what others think but I had my 1991 Civic Si even all around. And those who know me I'm a stickler as I had each corner within 1 millimeter of each other.

Taking weight off the front by lowering the rear more would make it understeer in my opinion.

What are you trying to complish by lowering the rear more? Less understeer? Or less heat into the tires?

 

lowering the rear will not "take weight off the front". at rest, your static corner weights will remain unchanged. as for handling dynamics, lowering the rear of the car relative to the front effectively softens the rear of the car, moving the car towards understeer.

However, how does it differ from cross-weighting, it is just shifting weight.

At this point it seems I want to raise the car up, then just dial the camber in.... however, I'm looking to better understand why I'm doing that. Do you have a link to a website that would have some explaination of this so I can better understand.

Prior to having the rear camber endlinks the only way we could get more camber in the rear was to lower the car, which we did to help an oversteering car. To the point that it was lower than any Civic I had driven in the past.

After loweing the car handling wasn't 'bad', we just wanted follow some advised of others and try to get more camber in the rear with the RT-615 tires. We couldn't get the amount of camber we were looking for without the endlink, so we installed the endlinks and dialed in the amount of camber we wanted ---&gt; at that point we didn't raise the car back up because running it lower didn't see to be bad.
