will more positive caster reduce exiting speed on corners?

 

No, slight positive caster causes more straight line stability, and a sharper turn in response.

 

thank you. i understand how it would increase sharper turn in response becuase it is leaning into the turn, which is a good thing. but doesnt the more tilt of the caster, the less road adhesion you get surface-area wise? and therefore, for exiting speed ( accelerating out of the turn), u have less traction , which means less power to the ground resulting in a slower exiting speed?

i was racing a friend a few days ago and he has zero caster, i have about +3 i think. my corner entry speed was faster than his, but he was able to close the gap between us after apex (exiting the corner). he drives a type SH . and we are both about equal in driving technique.

 

Wait...I think your talking about camber, not castor. Camber is the tilt of the wheel....i.e. if you stand in front of the car, you can see the top of the tire tilt in a little bit. Negative camber will help you cornering speeds, because as you turn hard, the wheel gets better contact with the road, as you stated.

Although, too much is obviously a bad thing. From what you described, it seems like you know how to brake better, meaning a higher entry speed. But the Prelude's H22 has the torque to pull the car out of the corner faster. If you want to beat him, dial in some camber, turn a little later into the corner, and floor it a little sooner. The back of the car almost will not slide, if you have a stock suspension, that is. FWD's don't turn as well as rear wheel drives, and I've seen professionals racing FWD's a lot.

They turn in really late, and turn hard, as to get the car pointed straight as quick as possible. Give that a try.

thanks for the tips. i actually do turn a little late when i m driving. however, i was not referring to camber.



i was referring to this. if the wheel is at positive caster, the edge of the tire should sit lower during a turn, thus decreasing surface area to the ground. do you guys get where i am getting at?

i was not referring to this.

 

Alright, now we are on the same page.

A little positive castor will help your cornering. I know that most of the champ cars, NASCARs, and other race cars all use a little positive castor.

I suppose the best bet to suspension tuning is to try something, see how it works, and then adjust it again.

Do integra's have adjustable castor?

 

To help you all out....

Surface area will help your torque reach the ground better and more evenly. The width of the tire doesn't matter when cornering to allow better traction. The tire could be 1/2 inch wide and still grab the ground as well as the 7 inch wide tire. This is called friction and it is based on a single point wereas torque is based on surface area. If you want to corner better, get your tires closer to the corners by increasing the caster in the positive direction.

 

ah... positive caster = better cornering.

what about exiting speed and acceleration?

no, integra's do not have adjustable caster. we have to swap UCA or get after market ball joints that connects the knuckle to the UCA ( i think, not sure)

 

i am not sure how caster works? does anyone mind explaining?

 

this man knows what he is talking about...I try to tell people all the time surface area is not what gives you traction.

 

sprint suspension sells a upper controll arm that has caster adjustments on it. but they only make it for the 96-00 civics

 

so while exiting a corner, is it torque or traction that i need more? seems like these are the 2 things that i cant both have at increasing amounts.

 

Too many factors to bring it down to caster. Look elsewhere.

0 caster sucks, +3 is a good thing, +5 is even better if you got the clearance.
