You can't ignore suspension travel questions if you want a reasonable answer as it is one of the most important factors when deciding on a ride height. The optimum ride height is the fastest ride height. Forgive me for being unhelpful.

 

Depends also on wheel size, springs.
Since your down under You have to look to your sanctioning body.
What tire size are you allowed to and are running.
Everyone is different in as much as some like our cars to perform differently.
I guess this falls under personal preference.
Look at other EG's competing with you, and see where they are.

I have 4 1/4 in the front and 4 5/8 rear and 2 inches travel. (stinky these are corrected measurements)
Its my preference.. but in time i may change that due to other changes I make to the chassis.

 

dirty, where is that height measured at? I'm ~5" at the jackpoints, and going lower would cause serious problems. I know we can't have a 2" difference in height

Weel, if you want more help we really need more details. "EG Civic" is not enough.

 

let me go back and check my paperwork where the measurements were taken from..
I know I wont go any lower than what it is at now. It will be in the opposite direction.

 

Stinky: I correct myself!
4 1/4 front
4 5/8 reat from the jack points.

Im glad I didnt go any lower.

 

Typically most HC and IT racers run at 5" to the jacking points at the front.

Dirty at 4" i'd'be pretty suprised if you had 2" of travel...

Weel you want to run the car as low as possible, with the following exceptions

You dont want the UCA hitting the fender well, you dont want the damper to bottom out, you dont want the RC below ground, you dont want the chassis (or any part on the car) to touch the ground, and you dont want the tire to run om the fender or chassis.

Typically the lower you go the more roll stiffness you need, so that you dont run out of travel via the UCA and upper fender well or the damper bottoming out.

 

Jimmy,
paperwork rechecked TFB performance says 2 inches.
This is good info to have below. Will be intune to look for this during the shakedown at Thill
