Corner Weight Set up

Does corner weighting means having equal weights on the left and right side of the car. How do you determine how high to have the front and rear of the car? Any suggestions on height of the front and rear of the car. I currently have the HKS Hipermax II and left the height settings as they were from the factory, which suprisingly they were equal on each side.

What it is balancing across the corners of the car, by keeping the car balaced across the corners it keeps one wheel from carring more weight. If you want to add (push) weight around (front to back you would change rake)(side to side you would change corner weight) the car to help turn in, braking or what ever you need to improve (but if you improve one you will almost always loose someplace else) and aspect of a car. Rake will determine where the car sits, if you leave it at the factory setting it will keep stock handling characteristics (sp?) but if you want to put a little more weight on the front to improve turn-in then raise the rear relative to the front. Do the oposite if you want less turn-in or more rear on throtle traction exiting a turn. Do a search on setting a car to learn more, the info makes good reading and will help a lot watching "those goofy nascar guys".

Corner weighting's objective is to get as close to a 50% cross weight as possible


You can see here in this before and after the cross weight of my (stock weight; nothing significant removed.. just my 150lbs **** in the driver's seat) '89 240SX. Before, it was 48.7%, and after 50.3%.
(rest of the alignment specs are here, just because i happen to remember the URL too!)

The only corner that was adjusted was the LR; notice its effect on the other corners.

The ride height from the ground should be as close to equal on each corner as possible to prevent any sort of rake.. a large rake between axles could lead to odd handling characteristics at low speeds, and uncomfortable conditions at high speeds.
The optimal ride height for better handling characteristics is often just having the lower control arms (from the center of the ball-joint...) level with the ground, which on the stock Evo is pretty much already the case.
Check with the coilover manufacture and see what they suggest, or, adjust the car to the stock height and 'test and tune' over time.

Unless you have a two task "to do" list... you know go fast and turn LEFT. My oval open class Kart is between 64% and 68% cross depending on the traction...
