front lower than rear, explain this?

[EK4R]

hey can any explain to me what would the effects be on a FF (EK) if say the front is about 1-2inchs lower than the rear?

would i achieve better traction being FF ?

what about handling? and under break?

how would these affect if the rear was higher than the front?

[EG5[KRT]]

i thnk that if the front is lower it upsets the balance of the car when turning hard due to the rear being of a higher centre of gravity ..

i had whiteline springs fitted to my dc5r last week and the rear springs haven't settled properly yet and is about 25-30mm higher than the front.

its not that much harder to drive except that it understeers fairly easily at the moment. im presuming that as the rear comes down properly that will correct itself.

you could avoid this though with a bigger rear sway, if you want to keep your car like this.

traction is not really any different.

With springs.. the rear is usually higher to compensate:

-Weight of Fuel
-Passengers
-Stuff in the boot

If you want even height... height adjustable coilovers is the only way to go.

then why would the front not be higher to compensate for mmm i dunno, the engine.

spring sets are generally designed to sit about the same level and have different spring rates to suit the front and rear.

my whitelines should have a wheel centre to top of the guard height of 345mm which the front does but there is something up with the rears which whiteline is looking into currently.

i guess to answer your question though EK4R for a road car you are best to have height settings pretty much the same front to rear.

[EK4R]

yea i know cheers for that.

i just wanted to know what would be the effect on the handling of the car if :

front higher than back
and
back higher than front

you guys told me if the front is lower, then i would increase understeer correct?

[matt]

more understeer is my experience. you could put a bigger rear sway bar in the rear to correct it but you might find it becomes unsettled easier given the higher centre of gravity.

[integral90]

having the front tilting down should give you better grip from a stop, seeing as the weight is leaning forward, but this would also make more understeer, more easily.

having the back higher should make the car more balanced under braking, seeing as the car should tilt to be about even. The traction from a stop would probably decrease as less weight is on the tyres.

[EK4R]

yea. or having my back higher i could deflat my front tyre bout 10psi ...hmm just a thought

thx for the feedback

[NogZ]

lol dont deflate anything to compensate for height. It will increase drag and screw your tyre wear.

Higher front would be lessening the rake of the car, increasing air pressure at the bottom front area and providing less grip at the front as you go faster (not good)

back higher than front, id say a lil less grip at the rear and more at the front -> a bit more oversteer. Theres lots of other things, but i think the above effect is the most noticeable.

rear height > front height is optimal, it is the stance of drag/circuit cars as its better for the car's aerodynamic err coefficient.


additin:

if the rear was considerably higher than the front from stock, worst situation your rear tyres will break traction if you have not changed the F/R brake bias

my car is lower at the front then it is in the rear and i hate it! lol in the rain, and in hard cornering, my car actually drifts! its sooo dangerous! im going toi slam the rear soon and see if that helps, cause its actually very scary driving in the rain and cornering at high speed...
