FWD lifting rear wheel... Bad??

[mossaidis]

It's nothing to worry about. You want those front tires on the ground all the time. You just need one (outside) rear tire on the ground at some point.

Not sure you can "tune" the rear lift without adversely affecting something else.

Tricycles don't corner as well as go karts. Porsches lift front tires and oversteer like MFs when the front to rear springing and sway bars aren't correct. Keeping all four on the track is important. We don't lift a rear tire on the Type R we run in the enduro races.

FWD needs the rear tire up about 3 in or less. If it is on the ground, that weight(30#+) is not transferred to the inside front tire.
It is a tick faster. Enouhg so that I have reduced the rear springs and added rear bar.

AKA "going faster in a FWD car."

Been doing it for three decades, dude. Gotta trust us on this one...Fiestas (and Golfs, and Integras, and Neons) ain't RWD, rear-engined Porsches.

But I encourage you to investigate, develop, and test the world's best-handling FWD car while working to keep both rear tires on the ground. Make it work and the world will beat a path to your door.

I wish you the best in your endeavors.

For the rest of us non-super-humans...lifting the rear tire is perfectly normal.

GA, who recognizes the rear tires on a FWD car have two basic, primordial purposes: keeping the gas tank from sparking on the ground, and making it look better on the used-car lot. And no, I didn't make that up myself, someone a lot smarter did...

Yep... Well tuned FWD cars will always end up lifting a rear wheel. How much/how far that rear wheels lifts is indicative of total front grip and roll rate. Personally, I've found the fastest setup (and coincidentally easiest to drive also) has limited rear wheel lift. Is it there? Sure. Is it a foot in the air? Nope.

I believe go karts have chassis flex built into them, and this is tuned, to create inside rear tire lift/unloading during cornering. Without that the kart will push like a dump truck.

Tricycles also have only one FRONT wheel and completely unrelated cg issues, so the metaphor is completely invalid. Not to mention big wheels corner faster than traditional tricycles.

+1 to not a bad thing to lift the rear tire a bit.

Can get around the "problem" and save on tire bills.....just put a big caster under the rear bumper.
