Yeah formula one cars run tons of negative camber up front. Some front wheel drive sprint/time attack cars too.

buuuuuut, if u look at the way their suspension compreses when they turn, the tire to the inside actually cambers in so its almost flat or flat on the ground. big difference between our cars. its like taking a car and setting it up for +.75* or +1* on the rear so when u launch while drag racing, when the rear end squats the tires camber out with squatting and theyre flat with the ground

It's from caster curves. The Drifworks s15 runs something like -5 degrees of front camber static, but the leading wheel in a turn has almost %100 contact patch during counter steer.

The wheels on F1 cars actually camber in during load and out during rebound. So the outside wheel will gain more negative camber in a turn while the leading wheel gains positive camber from rebound and caster.

your logic makes NO SENSE

when they turn the body roll makes the OUTER wheel flat, the inside would need to gain POSITIVE camber to be flat, NOT NEGATIVE, think about it...your making a left turn with negative camber your cars going to roll over to the RIGHT making your outer tyre flat and your inner one (following in the same direction) has less contact patch and even less if it cambers in more...so you would want it to gain positive camber if anything...

and your wrong AGAIN with what your saying... with your logic in drag, when your suspension compresses (squating) yes postitive camber would allow a flat surface when squatting since it will camber in...but your saying it cambers out?? no it dosnt it cambers in...squating=spring compression=lowering=negative camber...

^^^yes you were correct in this example but your explination as to why its set up that way is wrong which leads me to think you really dont know what your talking about

sorry :rolleyes:

well im sorry i typed inside and i said what i was trying to say wrong. jesus. but that is exactly right, it cambers in for a larger contact patch. god forbid somebody get in a hurry a have a typo d*mn. and when i said camber out as if in drag, i mean the top of the tire leaning in and the bottom leaning OUT i.e. negative camber. +.75 to +1 will give u a wider patch as the tire cambers out and the footprint of the tire becomes flatter with the surface of the ground. if it squats and the suspension compresses, then the a** of the car hunches lower to the ground which in term just like lowering will increase negative camber correct?

if you are blaming it on typos then you had a few in key typos in there

dont get me wrong man im not trying to be a punk beezy, im just trying to keep correct info out there for the rest of the people as well as you insulting my cars set up be like insuting my momma lol

future refference man...when you say IN and OUT its more associated with toe not camber...which is associated wit POSITIVE and NEGATIVE...just so you know i mean i guess you can describe it as in and out but if your cambered in its still negative IMO not wat your describing looking at the bottom of the wheel being pushed out...thats just a**-backwards..another future refference its called contact patch not footprint

i mean you did work at firestone as a master alignment tech so i sort of assumed you knew the above things already

and Out to win...we were using the cars as examples of front negative camber because ^said it was stupid for me to have as much as i do

yes its no where close to what size tyre should be run on a 17x9 and has nothing to do with this subject whatsoever but it could be used for future refference maybe :mike

all around? you dont think 225 45 might be a bit bulky in the front? i think this could be run though, however, i would go 225 40 to save some clearance issues

yeah all around. I don't know how low you plan on going, but here is 2 pics of mine 225/40/18 on 18x9.5 +15 all around
Had to roll the fenders a little, tires rub on inner fender walls when making full lock turns, but I have tien tie rod spacers too.
You could go with the 225/40 in the front, but I just don't like the look of staggered tires, especially cause if you notice on 240s and most cars the rear usually sits lower, even though my sideskirts are level to the ground so you'll just be making a bigger tire to fender wheel gap if you run a smaller tire in the front.

i don't know it really depends though because 225/40/17 can look good all around to as long as he's low enough

well sorry if my wording confused you and actually i didnt mean to insult your car or your set up, where im from nobody around here (that i kno of) runs anything like that -5 so seeing that was like whoa! and i understand the whole car/momma thing, id kill over mine too. what i do kno and am trying to say is ive lined up all of my friends cars like i did mine and it seems to work. if yours works for you then hell yeah man, rock the sh*t out of it. we all use what works for us and to each his own
