Are the torsion bars matched to the front spring rates correctly? When I changed the rear bars before changing the front springs to be stiffer on mine a few years ago, it became amazingly tail happy.Stiffened up the front to match and it was fine. As people are saying, if it's toeing in, it should increase stability. Toe out will make it a bit tougher to handle. |

I'm not getting at you, I'm trying to help? I have no idea of your line, what you did with the throttle etc etc! You can make any car rotate during a bend if you know/don't know what you're doing.What is your rear ride height? Sounds like it's too low which will give you more toe in and less damper travel. I suggest you do some research into toe on the rear of fwd cars as I think you're looking in the wrong place buddy. ________________________________________ www.bridgecraftmotorsport.co.uk |

I wish the race car was as unstable as that, have to work damn hard to get that thing to rotate! Going to 0 toe at some point soon though  ________________________________________ Rallye Race Car |

Hey dude, as requested:Rear Toe Left 0.56' Rear Camber Left -2.57' Rear Toe Right 0.54' Rear Camber Right -2.53' We work on "minutes" so 0.60' = 1.00' so to speak. ________________________________________ |

Judging by the camber/toe it's a bit low. Beams nice and square which is unusual. Not quite sure how you can say it's the same height as martins, his beam sat an inch further up into the car so has little relevance. Ride height, rake, spring rates are VERY important if you want it to handle right so any info may help you diagnose it. I'll happily do you some arms with 0toe or toe out but I'm not sure it will help this problem at all. ________________________________________ www.bridgecraftmotorsport.co.uk |

Sounds like an odd situation, sure there wasn't some oil on the track or something? Shouldn't break away under power like that, even if you had loads of toe out it still shouldn't break away under power. There's not many 306's that hit 130mph on track so possibly the back end lifted and went light or something? Mine seemed ok at 130+ at the Nurburgring but that was only for a brief period before you're on the brakes. From memory Martins were standard toe but with additional camber? ________________________________________ Oulton Park in a BTCC 306 vid 1Oulton Park in a BTCC 306 vid 2 Lap of the 'ring |

I wouldn't attempt running 36psi in 1b tyres! I'm of the same mind as welshpug to be honest. Rough surface and little to no rear suspension travel will have upset things. As Pete says, under power the car should be being dragged where the front wheels are pointing, even with rear toe out. My car also has the same arms and I've never had a problem. To be fair mine won't pull 130 there either but it does in a couple of places at the ring, if I had no confidence in the arms I can assure you I wouldn't be doing 130+ through fox holes! ________________________________________ www.bridgecraftmotorsport.co.uk |

I'd call the R1R more of a wet tyre so maybe try R888s and see how it goes then.________________________________________ Rallye Race Car |

Hitting 145 before the rise and 130 at folly?! I think your speedo is out or your lying!My 205 will hit around 130 up the rise and that's with a decent level of grip and on R888's out of camp. Hell even the front running saloon race cars aren't doing 145! And you've got crap road tyres as you've said above. What's your lap times? ________________________________________ 230 hp 2.1 16v XU 205 rallye on jenveys Project thread here309 3dr K20 Type R |

I know a group A+ e30 will pull 150 over the rise, slicks and proper dampers, circa 1000kg kerb weight and not that much power but it is on the limiter.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

I got the ride height setting from Martin, 285mm between bolt centres. That's the measurement directly from the beam on his 306 from the ring taxi video.  ________________________________________ Get used to seeing the yellow one !!!

Martins ran Peugeot 23.5mm bars, not sure what this beam is as he seems reluctant to tell us any of the spec! ________________________________________ www.bridgecraftmotorsport.co.uk |
