2 suggestions.

1) there should be a recomended starting point in the instructions that came with the shocks. Also try checking that companies website. They might have a database for most vehicles.

2) Spring Preload - ADJUST THIS FIRST. I'm not sure about cars, but on motorcycles 1/3-1/2 of the total travel shock travel should be sag.

3) Dampeneing - If in doubt, start with the dampening dialed set all the way out. Add dempeneing by adjusting it a few clicks or 1/4 turns in on the adjusters until the ride is controlled. Start with rebound dameneing first. As a rule, you want as little dempening as possible to maintain control of the car in all settings.



That's what I know from motorcycles which are probably easier to set-up and adjust in general sicne a rider of a motorcycle is far more in tune with what the vehicle is doing than a driver of a car.

 

motoguy128 had some good input for you. However, to everyone else's point, we don't ride in your car and don't know your driving style or the road or track types you are dealing with.

The manufacturer probably has some suggested points to start at or some suggestions for a "generic" setting.

It's a trial and error type of thing. Try something, test it, and so on... It's not necessarily like setting your tire pressure. And even IF it were, when it comes down to actually racing, even tire pressures are trial and error for your car, your set-up, your driving style, and the road surface, etc.

Good luck.

 

I'm a big noob, what do you mean by adjust your settings and stuff

 

thanks man, i get them today, so i will check otu what it says

i dont know or didnt know illuminas had spring preload settings. but thanks for the advice,


its nice when some of u guys can actaully answer a question. thanks for being some of the few helpfull adults here

 

I've never messed with shocks in cars. I honestly don't know what type of shock this is. I was assuming it's a coil over, meaning the spring fits around the outside of the shock.

I will note that most people tend to use too stiff of springs, or too much preload. They also use too mch dampening. It's one of those cases where less is more. Your goal is to keep the wheel in contact with the pavement not nessesarily prevent body roll. That's more the job of the chassis and anti-roll bars. It all must be balanced. Unless you have a stiff chassi like in a race car, it's not realiztice to have a ultra stiff suspension. It won't respond properly.
