just to answer my own question: 3 inch GAIN , thats right i gained 3 inches


2400-2500lb car + ohlins road and track set to max ride height + 800 springs front 1000 back + 0 preload front 15 preload back = 29- 30 inches ride height vs oem 25-26 inches stock


time to twist those lower cups.....

10,000?

10K? That stands for KG/mm bruv.

You got a 3" gain because you used 15mm of preload (why?) and probably have the shock body set too tall. Not surprising since these are adjustable....

The front preload setting also doesn't make sense...

thats what the stock body weight 2700-2800 calls for , obviously 200-300lb of weight reduction changes things up a bit , im going to set the lower cups to "max low" and reduce the rear pre load to 8-10 and see what the out come is

Slightly off topic, but what did you do to cut the weight out of your car?

Remove all the pre load, that's your biggest issue. Approx half your travel should be split between droop and up stroke.

Preload for a stock weight S2000 on Ohlins with 10K rear springs is something like 9-10mm (IIRC).

On a stock car...front preload for 10K springs is fine at 0. But you need to measure to get the right number for your car and set your 8K springs.

Is there an actual shock travel measurement you're after?

I'm guessing you want the car to oversteer, judging by the spring rate choice?

I think you should probably weigh that car...
Idk about 2-300LB...

So...your car weighs 50-75lbs less per corner (on average), according to your predicted weight loss.

If your predicted weight loss is ALL sprung weight and is correct....do you believe those numbers to cause like a 4" lift? ehhh....

Like...if you took a stock height S2000 on 10K springs and you grabbed the fender well and lifted upward with 50-75LB of force...you wouldn't get a 4" lift...knowwhatImean? .....

Or...inversely, if you put a 50-75LB load onto a corner of a S2000 with 10K springs, would it sink 4"?

That ride height is not because of the weight loss, my main man.

The measurement you used for your setup is MASSIVELY wrong, is my point. Or there is something wrong with the install that you should probably check on.

Did you forget to remove the jack when you took that pic?
