That's not really a great idea. But yeah, toe-in makes the car track straight, because you're scrubbing the tires while going straight. Bad for tire wear and for steering feel.

Will it be more "wobbly"? No. It will be more responsive as the wheels are now pointed straight, not scrubbing while going straight.

 

not really. toe scrubs the tire when going straight (in or out), so whatever angle the tire is at is what will wear. zero camber will wear even (assuming it's not over or under inflated). negative camber will wear the inside edge, positive camber the outside edge.

Toe-in is common as it, as you pointed out, keeps the car tracking straight. Also, since both camber and toe change as the suspension compresses, a lot of OEM's will set a static toe-in to get them a loaded or dynamic ideal toe setting.

For example, say the rear suspension toe's out under compression. They don't want the driver to have the loaded rear to run into a toe-out situation when they are fully loaded in a corner (thus "steering" from the back), so they will set a static toe in rear value such that under full load, the rear ends up at a zero toe.

The ideal solution in terms of tire wear would be zero toe all around. I have yet to drive any car that doesn't drive better with zero front toe then it did with toe-in.

Additionally, caster helps self-center your steering wheel, and also helps gain camber on the loaded wheel to get better use of the tires contact patch.

 

Bumping old thread...

Thanks for the info Ryan !

I just got my alignment redone with zero toe ... HOLY MACARONI ! What a difference, with max negative camber on the stock front suspension and zero toe it is a completely different car. Much crisper turn-in, much more bite through corners, I feel like I can put more power down all through a corner, and it's much easier to turn, particularly at low speed the tires don't scrub and crab so much in hard turns.

The only drawback I've felt so far is that the car does go squirelly on really hard braking. Not a big deal if you're ready for it and keep good control of the wheel, but could catch you out if you're not paying attention and have to do a sudden emergency stop.

 

Yes, alignment makes a world of difference. I just ordered a set of GT3 lower arms so that I can get a bit more camber for the R6's I am going to be running on the track - it will be interesting to see if there is any adverse effect on my street tire wear.

 

yep, with 0 toe in front you cannot just keep drinking cofee while driving your car.
get 996 GT3 LCAs on - and you will have yet an another divine intervention.
