ok, nice and simple... now that my 944 is running and mot'd n stuff .. it'd be quite nice if it didnt pull to the right, tramline, hop about when turning left and feel all floaty and vague when turning right .. it does other weird things too but it'd be labouring the point to list them all basically .. some PO has been in there swapping out knackered bits .. and never had it setup afterwards. Parked on a flat and level surface (tesco's petrol station to be precise) all 4 wheels display visibly differing camber and toe adjustments.. so.. where to take it ? bearing in mind im currently based in Carmarthen which is.. well, miles from anywhere. any recommends ? |

Well Zimm If you come up to Stourbridge then you need to make a diversion to the guy that Demonfish and I use However from what you say about your car, I would gusstimate that it will need to be worked on for about one day to sort it anywhere near properly What a drive back though if you use the M50, A40 and A49 |

oh yeh .. got my local place to chuck the gauges on it this afternoon even though they didnt have the time/tools/experience to do anything about it.. front end isnt too bad.. smidge of toe out and very little camber.. but nearly the same each side.. however i suspect the rack's not been centred correctly. the back end however was so far out it was silly OSR ~5 deg neg camber, smidge of toe in NSR ~2 deg pos camber, considerable toe out ! no wonder it felt odd. figured it was SO far out i couldnt make it worse, and armed with the internet and haynes manual (useless) got the jack out. aiming for 1-2 deg neg camber and straight tracking the OSR is now a LOT better, NSR didnt want to play ball before the light faded.. but YAY it almost goes in a straight line, and feels a million times better turning left might have another crack at the NSR tomorrow, i know I dont stand a chance of getting it spot on, but it's already better than it was. |

Its amazing how much a min makes to the handling, tyre wear and fuel consumption. A tad of toe in at the front will give you a stable car in a straight line for sure, and one to one and a half camber is about right IMHO. The rears should have no toe and be nice and parallel. Once you've got it roughly right enjoy it, but at some point you should get it done by a man with a laser alinger etc. Have you had it corner weighted and balanced? If not, then consider getting that done before the geometry. Theres a discussion that may be of interest here Good work though. |

Hi Zimm, The guy Demonfish and I use is not in Stourbridge, he is about 40 minutes away by car He is Chris Franklin and he operates just outside Atherstone on the A5, in Warwickshire You can see his web site at http://www.centergravity.co.uk You can "speak" to him at info@centergravity.co.uk Unfortunately I seem to have mislaid his telephone number The only thing he does for a living is set up performance cars and he is a member of TIPEC He also does development work for a number of suspension manufacturers and a company that makes replica Porsches He will do want ever you want, within reason, and will need to "interview" you before starting on your car He isn't cheap but he is b****y good See latest edition of All Torque if you are a club member Hope this helps |

so.. having phoned around my local (ish) mazda dealer swore blind they could do the job .. got there, double checked that they knew what they were doing and sat down to have a coffee. chap comes through, "there isnt any adjustmnent on the back of a porsche" went out to the workshop and explained to them how to do it result ? they snapped the eccentric, denied availability of a courtesy car, are ordering a new eccentric and have refused to complete the setup, or cover the cost of the hire car i now need for the next few days. not happy ! if they have the temerity to even think about presenting me with a bill for fixing what they've broken an awful lot of shouting will ensue. |

oh, i got a quote from centre gravity, lots more than i was quoted locally, but in light of todays high jinks, more than likely worth the extra, and the trip up there. |

Hi Zimm Sorry to hear about the Madza problems (I did check the spelling) If you are a member of TIPEC check out page 9 of the June 2008 edition of All Torque It could save you some money Also ensure tyres and suspension in good condition otherwise you may end up having to have extra work done in the near future after visiting Centergravity. I suppose the hard lesson here is you only get what you pay for Specialist job and specialist skills, sorry to harp on. I was up at Chris's place yesterday and a guy was there having driven from Somerset just to get his car done I have seen people there from off mainland UK with their cars before now Hope all works out well for you Finally, know how heavy you are, car will be set up with your weight in it and also you need to have a full tank of gas onboard preferably. |
