I do know I know have a bit more understeer? That's where your second q comes in Quote:
Its a pity there isn't a bigger front roll bar, as I would like a little less roll. So I'll probably have to get a bit stiffer front springs (again ). Car is still comfortable enough I feel, so I think its a logical option to try first. Hope that answered your q? As you see, these things are car-specific and probably rather personal too, so there's really no "always-good-set-up" to be had... |

It looks good on track we just need to get you a better in car camera Were you going all out or still taking it easy? Looks like you could have taken those corners a bit faster That porsche driver must have been annoyed at best or red-misting at worst, getting passed by a beetle!
For the shocks I vote Koni or QA1 double adjustable rear and a koni double adjustable front. I'm still dialing mine in and I have an autox this weekend to test, but I've been very happy with them so far. |

_I_ was going all out for my doing, but was a bit carefull (and not skillfull enough) in the corners and not at max boost (tad over 1 bar) and obviously the car can do much more then I dare or am capable of. The 911RS I overtook so easily did run 2 seconds faster on his fastest round and unlike me, he was pretty consistent. That shows to me the car can run much better lap times, its just the driver that lacks at this point... |

However, more front rollstiffness will generally tend to more understeer. |

The balance is actually pretty good. Its just that the front tires seemed to have suffered more then the rears and on one very tight corner, I wished for a little less understeer, but maybe I should have turned in later there.. |

It's tough to tell from the photos but the inside front tyre looks a little light in the bends. In other words, the inside front is not planted and the front grip is mostly relying on the outside tyre.
It looks like the outer rear has compressed a bit far leading to the inner front lifting (the diagonal effect). I'd suggest a slightly tighter rear antiroll bar or perhaps ideally, slightly stiffer rear springs. A looser front bar might also work but more lean has other issues. You could also try increasing the front rebound and see if that helps. |

what camber are you running at the front? i found the best set up for mine was to have the rear quite soft and the front fairly stiff.
run 130lb front springs and a h/d bug pack anti roll bar, rear bars are 944 and the 944 anti roll bar. front camber is -3* and rear is -2.5* front toe is set to 0 and the rear has 1.5 toe out. it will pick the inside front wheel up but at least thats getting as much wieght as poss on the powered wheels which helps combat the wheel spin. i found that high speed corners were improved when i fitted the front spoiler and splitter and improved again when i fitted the dive planes. guessing this will all change now i have fitted the lsd.

Your rear 944 torsion bars are 23mm. I run 25,5mm (M030) bars. Your rear 944 anti roll bar is what? 17mm?. I run a 24mm Whiteline anti roll bar in the rear... My front springs are already 50 lbs up over what Lee send them with. IIRC I now have 350lbs springs... That why I said each car is so different. Mine is probably so much heavier and therefore needs more of everything I guess. |

Wow... you are already running a pretty tight rear.
How about replacing the side and rear windows with Perspex to reduce the high up weight? Or would that cause legal problems with road use in NL? Like the the "I'll be baack" style glasses |

You found me Bruce
and I already have lexan sides (door window, rear sides) and rear window.. Yeah, suspected as much, but really I probably would like this set-up better anyways. It IS after all really not a 'full on track car' either. I drove 2 hours one way to the track, so _some_ suspension movement is desireble still just to arrive fit and be able to 'race' in good spirit |

and the very next day/evening I was on 'drive-my-friends-to-be-graduated-son-to-pram duty' :
running at idle for over half an hour in queue...he was happy though |

Looks like you had a fantastic time Walter, thanks for posting the results.
In your opinion, for the type of driving you have done on the long tracks, would you consider adding a limited slip diff ? Or would this potential addition not be worth it ? How about for the drag strip ? Thanks. Sandeep |

For last monday I didn't really missed it, but then again, I can hardly tell what its like with one. I have missed it before on the circuit when I mistook inner wheel spinning for clutch slip (the latter it wasnt). Now with more spring and less overhang, I can get away without it or so it seems, but still wished I had it onboard. For drag racing I really miss a Diff, any diff I would say as I almost always get one-wheel burn-outs which really sucks and is almost dangerous because of the different traction left-right it results in. If I get a financial break, an LSD from Paul Guard is the first thing on my list 4sure! |
