Well I've done some searching on this topic and from that I've learned that corner weighting adjusts how much weight goes to each wheel, or basically. I do have a few questions still unanswered:
1) When a car is corner weighted is the drivers weight factored or can be factored in to it?
2) Can the stock suspension be corner weighted?
3) Will I see any significant improvement w/ the stock suspension, or should I not waste my time and wait til I can afford aftermarket coilovers? (considering JICs or Ohlins right now)

Thanks for any information that you can provide.

 

Evo like most cars is front heavy put a 100 lb stereo in the back that helps lol

Sway bars and stabalizer bars can help a lot for better suspension. I still use stock suspension on my car because I like having the ground clearance and because I keep coming across stories of even good aftermarket suspension lowering the cars ability.

 

Respectfully, all of this has nothing to do with corner weighting.

No you cant corner weight the stock suspension, but if you could it would greatly improve the handleing of the stock set up by more evenly distributing coner leads. Both he JIC and Ohlin coil overs can be corner weighted.

1- this is the decision of whom ever does the job for you some of my friends who run E30 race cars do it with their weight factored in, many shops though will just set it up based on the car with out drive or passenger.

2- No

3- There are ways you could significatly improve the stock suspension with out coilovers, but none of them will appraoch what a truely well tuned set of coil overs can achieve.

 

Thanks for the info.

 

I had my EVO corner weighted at an autocross.

basically on the stock EVO with no sunroof, the car has an excellent balence. (51%/49%) front to rear with a perfect 50/50 split left to right diagnonal.

With the driver (@200lbs) the balence changed to 60/40 front to rear.

 

IMHO, corner weighing is only important if you are competing with the car. Corner balancing can only be performed with height adjustable struts, and can make a difference of 0.1 to 0.3 seconds, for example, on an autocross course of 60 secs. Well, for majority of people, that is nothing to be worried about; but if you look at the National Finale at Topeka last week, that few 10ths are the difference between 1st and 7th places in many of the classes.

Corner weighing should be done with the driver or simulated driver weight and competition fuel levels. 51%/49% diagonal balance is considered "poor" in terms of corner weighing. We perform corner weighing and we don't stop until we can get within 0.1% of 50%/50% diagonal balance; otherwise customers would be wasting money.

For street driving or non-serious competition, don't worry about corner balance.

 

Thanks again.

 

What if the cornerweighting is done without compensating for the driver weight? That sounds like a guarantee for having diagonal weight across the car?

 

My Evo stock w/sunroof & wing was only off 3/10 a percent with me in the car. This could be adjusted by sliding a piece of tubing over your spring at the seat(old showroom stock trick).

 

how do you actually perform the corner weighting? what equipment do you need?

 

Adjust the height of each corner to shift the weight using 4 scales, one under each wheel.
