lift up your back end ;)

This may seem a strange question but do any of you know why the rear of most chassis come up at an angle ??

I don't know if this is the real reason, but the back end of the car sweeping up will help reduce the lift a car makes. However, I imagine it would only make any significant difference if the whole underside of the car is flat. I guess it might help make the car more stable at motorway speeds.

No idea really, can't think of any other reason tho!!

Mine is higher at the rear because the shocks at the front are inclined and the back ones are upright.

If the car was higher at the front it would tend to create lift.

The inverse may cause the car to hold the road a bit better - at least not go light at speed.

I plan to have my car run a little lower at the front than the rear.

Have i read this differently to everyone else. Glenn has asked (and correct me if i am wrong) why the REAR MOST part of the CHASSIS comes up at an angle, nothing to do with angle of shocks??? and not about ride height either.

Glenn, i think its cosmetic, it can't be aero dynamic because as go said you would need a flat tray under the car from front to rear for that to work or at the very least a flat tray from the axle back.

No , Viper you didn't read it wrong, everyone else did sorry guys.

I guessed it would be cosmetic, for aerodynamic purposes it does help to have a slight lift on the rear underside since this causes an area of low pressure sucking the air from underneath and causing a little ground effect but this requires a compleatly flat underside.

I would have thought it was possibly for ground clearance as well.
It is the only overhanging part of the car and could if straight ground out when going in and out of driveways or filling stations.

Just a thought!

That's what I've always thought.
Kind of like the back end of a bus.

thats what I figured. the back of my fairlane has a little kick up for its huge ass....almost 3' of overhang in the back. it will still drag in some drives though but not too often. I wouldn't think of it being much of a prob on a locost since it is so short but for loading on a trailer it might be needed more.

Another benefit... maybe... the rear tire will hit a curb before the body work does? Hadn't considered it until now. Cheers. - Jim M.
