Tarret swaybars now on and tested on track. I set them to 95% of max forward and 60% at the rear. With 255s around the car the balance is a benign understeer. Wll try like this until i have enough confidence to go towards oversteer.



It is easy to understand the negatives of too stiff springs/dampers. How about the harm og setting the swaybars too stiff?

sway bar adjustments are only going to mask the problem

I am not sure which problem you are referring to. The problem I have experienced was a sudden oversteer. I later found that one of the shocks where set differntly forward. Being softer one side the car nosedived at turn in which loosened the rear end. The other problem has been a feeling that the sways did not matched the stiff suspension.



I know you think the car is too low (roll center too low) and under car bracing is needed. I have however not found other parties supporting this so I have chosen to stay where I am on those points. Perhaps we can agree to leave those factors out of the discussion for the time beeing? Or maybee this is like discussing possible causes of liver deterioration with an alcoholic... <img src="/forum/images/smilies/968/rolleyes.gif" class="smilie" alt="" /> leaving out the booze? <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" />



So if there is no basic problem to start with, then what problems can an overly eager setting on the sways cause?



I set the forward sway bar almost to max reasoning that my 800 lb front springs would be much stiffer than even a "club sport" type setting and that the swaybars should match the other suspension components in stiffness. I went to 60% at the rear to be sure that I started from understeer with no nasty surprises. The car drove well enougn not to be passed by any GT 3s on the R 1 session (semi quick drivers) and be upgraded to R2 (quickest group in the Swedish Porsche club meets) where it played midfield so it should be somewhat OK <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" /> .

I wouldn't worry about how they match your springs, you are in the ballpark. Use them as balance tuning devices. I would start with both of them set to the middle setting then soften the end that needs more grip. When you run out of adjustment, start stiffening the other end. If that doesn't do it, change spring ratios or other setup parameters.

personally, i think you have a LOT of problems in the setup - but, i'm going to stay out of this one now, because i think that anything i point you to is only going to frustrate things - i do wish i had the car here - i would change some things here, at my expense, just to let you go out and see for yourself how much faster it can be when it's right

Had the car out on another race track today. The one of my club. We had a race car test session and they let my "street" car out on the track. Much easier to drive quickly than the E 30 BMW M3 we drive int the endurance races. And the balance seems about right so will stay here mformsome time before changing. Interrestingly the car almost felt soft compared to the agricultural M 3.
