1) Why is March 27th Buttonwillow event not on the schedule?

2) Are bumpsteer kits points? Do they really add no significant advantage, in particular on AP1?

 

i've seen -2.1 with 6+ caster on stock ride height (ketsup)

when my car was stock i always max out caster first, then camber, i got 6.0~6.5 caster and 1.8 max camber

did you actually calculate out the roll center is OFF at -2.2 camber? where is considered OFF?

where is your roll center exactly at? and where is your center gravity exactly at? what's the difference of your distance of those 2 points vs stock?

i actually run slower with -3.0~-3.5 camber, if all fast guys run -3.5 with max caster, then i'm not one of the fast guys, i'm always not!

 

i ran out of money before i can take them off, that's why i'm asking you to pay for the labor!

let me know you have saved up the money to prove me/maxrev/kel wrong!

In order to get -2.2 camber up front with max caster near 4.5 to 5.0 you would be at a height of 20 inches from the bottom wheel lip to the fender. That is really to low for most coil over systems. In most cases you would be hitting the bump steer. Also being that low will mess up your roll center yes. So stating that you can get that on a stock car really dose not matter because you just f up the suspension.

This is taken from the Js website.

WHAT IS ROLL CENTER ?
While a vehicle corners, the movement of suspension is focused on the intersection (instant center) of the lines extended from the upper and lower suspension arms.
The intersection between the line from where the wheel contacts the road to the instant center (Point P) and the vehicle body centerline is the roll center (Point B).
With the stock suspension, the appropriate roll center has already been set from the factory. (Fig. 1)
ROLL INCREASES AFTER LOWERING?
Simply lowering the car results in an increase in the distance between the center of mass (Point A) and roll center (Point B) of the vehicle, even though the center of mass has dropped.
When the distance between Point A and B increases, roll stiffness decreases, causing an increase in the amount of roll. The amount of roll can be controlled with the use of stiffer springs, but ride quality etc. suffers as a result. Cornering speed does not increase like originally thought. (Fig. 2)
ROLL CENTER ADJUSTED !
With the Roll Center Adjuster in place, the angle of the lower are is revised. Roll center (Point B) is once again close to the center of mass (Point A) of the vehicle.
With the lowered center of mass and increased roll stiffness, the limit of cornering speed increases.
ROLL CENTER ADJUSTER FF
When a FF/FR vehicle is lowered, the angle of the lower arm becomes poor, resulting in a significantly lowered roll center.
Consequently, the amount of roll in corners increase and the cornering force is sacrificed.
By extending the ball joint of the front knuckle, the position of the roll center is altered. Replacing the stock ball joint with this product will result in reduced roll, and cornering force as a result is increased. Steering response is alsoimproved. This product is the long-awaited part for FF/FR vehicles.

 

all points this week. probably a car with all season tires will win this weekend

 

so is this going to be the case? i'd like to know by tonight so i know what to do when i prep the car tonight and be read before leaving tomorrow

 

I am near stock height on coils and have -2.2 front camber and 6 caster. I can get you a template of the alignment settings if you don't believe it. It's doable.

i can take off my wing and run all seasons, then i'm in street class!
