Increasing ride height after corner weighting
Discussion
Hi all,
First post from a long time lurker, here
My S2 Elise has been corner weighted after installing new Quantum dampers, but I have found it a bit too low (garage entry issues!)
What does it happen if I compress all four damper springs of, let's say, five ring turns?
At first sight, one would say "nothing" because all four corners will be lifted of the same amount, but having different spring rates front/rear (325/400 lbs) and different weights on every wheel I think this is no more true.
I do not need a huge increase in ride height, just 10-15 mm or so.
Will I screw out the car balance and should I better go back to my garage or will it be out of a few kilos only and I can live with it?

Adjusting ride height will change the camber due to unequal length wishbones, so don't do it if you can avoid it.
that's the least of the problems if you had it geo'ed at said right hight.toe changes would be more problematic, but it just depends what hight all the Geo was done at.
way I read it, he just had it corner weighted and in the process it's gone too low.
The car geo was made at lower ride height, so toe and camber could be slightly out, now, but I can correct this problem in house with string and pole method, I have done this many times with good results.
My doubt was about corner weights only, because I do not have corner scales and should go back to the garage to set these up, but I understand this is luckily not necessary.
Thank all you for your help!
BTW, yesterday I have been at Rijeka track, very well known circuit for me, fast and with aggressive tarmac. The new Quantum Zero dampers behaved really well. A bit too soft, may be, even with their hardest suggested springs (325/400 lbs) but, hey, they were made for the street and showed they can also withstand such a hard use. Most of all, they allowed to confidently brake on the first very bumpy corner, where you arrive at 130 Mph and when I was not safe with previous 500/650 springs I had on the Nitrons.
And now, as usual when something is good, I am looking for something better, like adjustable Quantums, even if I know that I use the car on the road more than on the track!

Camber and toe change will be small and not worth worrying about.
Btw, I think compressing springs increases their rate, but that may be the only way to move it higher.
not with (std} linear springs it doesn't.Btw, I think compressing springs increases their rate, but that may be the only way to move it higher.
all your doing is increasing pre-load, which is not a problem until it is a significant % of the static load.
