Improving turning radius/ratio of the FX

HI as the title said i'm looking for some info on how to improve the FX turning Radius.. i looking into this cause tho the FX is really sporty.. most of the time it turns like a huge sedan.

i found out that by extending the outer tie rods you can increase the turning radius of the vehicle.. something that all Formula D teams do to their cars.

so by improving the turning radius of the FX.. what kind of problems (if any) would i be running into?

thank you guys!






i being searching and lookin

it's turning ratio. when you extend the tierods you are changing the toe of the front wheels. this won't make much difference at slow speed for the fx anyway, & won't make it turn much tighter, but will cause your tires to wear badly.

increasing toe in or toe out is a tuning method for a car that is being pushed o the edge... on race cars they go through tires like you go through lunch... this really wouldn't help you much & makes more difference at higher speeds anyway

the turning ratio is determined by where the wheels actually stop lock to lock. big wide wheels will decrease how much the wheels can be turned. to make much difference you'd have to go with narrower wheels in the front & then adjust the wheel stops to allow more turning,might even take some modifyig of the rack & pinion too if that's already turning to max anyway. if you tried to do this with existing wheels they will rub, so you can't really turn them more... might even take some modifyig of the rack & pinion too if that's already turning to max anyway

best way to turn much tighter in the fx is the way ken block does it:tongue:

Speaking of turning radius; Is the rack & pinion assembly from the G different, and if so is it interchangeable? The only reason I ask is that my mother-in-law's Maxima has the turning radius of a 747 and I don't remember the same being true of my loaner G37x. Is that a difference in the rack & pinion assemblies or a difference in wheel stop settings? I'm assuming the latter is more likely...

Radius aside, it might be cool to swap the R&P (if that's possible) to achieve a slightly quicker turning RATIO.
 
sort of on topic, but Jeff made a good point on replacing the outer tie rods to know how many turns to remove the tie rod, so you know to do the same when replacing them.

Doing them this weekend if I can find a ball joint separator from the auto store to borrow. Hopefully Jeff's suggestion will avoid from me having to get an alignment afterwards.

Turning radius is okay on the FX, I found it a bit getting used to for parallel parking and U turns. My previous cars could take a U turn on a car in one shot, the FX, 2 (backing up once and going again). Not that I do U turns often, but something I noticed.

You can put on like 50 mm spacers and 25" tires too! =)
 
yeah, actually turning ratio is of course the difference between how much steering is put in vs how much is put out, in other words the quickness of the steering as a ratio in:out. in steering boxes they were usually something like 2:1 for non power assist, where power assist could be much quicker, 3:1, 3.5:1 etc, but I have also seen many refer to the turning radius as the turning ratio too. now I guess I know that technically that use of the term is probably not fully correct but I've seen it used by many through the years & I kinda assumed that's what rubare ment by radio so I just went with it :wink (2): Hey, we got new smilies!!!:nerd (2):

ha yeah, I came from old people cars -- Benz's that had a crazy ratio where weak old people can turn the steering wheel with no issues, and a slight turn, completely turns the wheels.

This thread had me all confused like you said John, I saw turning radius, turning ratios and turning radios! John, you know the ratio of the radio knobs? :alien::mask::sluggish: ahah those are new too.

You mean "turning radius" right?

Yes Dr.. That's what I meant..

Exactly doing U turns and tight turns on the FX is a mission.. I live in VA but I like to hang out in DC.. Where the roads change everday due to different things going on.. So everytime I have to turn around quickly all I say is "here we go again"

Also can a moderator fix the thread's title to the right word so people don't get confused.. I think the right word would be "Radius"

even tho I I thought Ratio would have being ok too.. Lol

Thanks everyone.. So only thing one can gain out of extending the tie rods is camber toes and uneven wear of the tires..

So my question now is.. Is there any possible way to improve it while maintaining the FX under oem specs?
 
Maxima is FWD with the VQ transversely mounted, so there's not a lot of room for the wheels to turn. So it's likely the wheel stop settings.
