The 30mm does make quite a difference, it made the rear end of my '6' nice and stiff and coupled with the solid mounts it makes it very predictable which is a quality that I look for in a car. I fitted the 21mm TB's at the same time and the whole setup seems to really work well.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

An update on my handling issues. I have fitted the Koni yellow shocks and 30mm lowered springs to the GTI and handing seems better, however I will see what it is made of this weekend at the track. I think I will need to stiffen the rear torsion bars as it has bottomed out a few times now. I lowed the rear 30mm [same as the front] and the rear looks lower than the front. What height do most people set there rear to front height ratios at and why?Cheers. |

I don't set them lower than 322 between damper bolts on standard bars, equates to about 25mm rear drop, works well with Eibach springs which are reputed to be a 30mm front drop.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

You need to measure on a flat hard surface from the chassis rails underneath (if they aren't too crusty). Ideally you want a bit of rake to the front (nose down). ________________________________________ Nothing to see here |

Depends on the dampers used (if they have the correct height platforms) and engine weight - aircon/airbags etc for the front. And of course on the front/rear height/weight distribution. Torsion bars are a pain in the arse ________________________________________ Nothing to see here |

Out of interest, where can we get 30mm ARBs from?  ________________________________________ Rallye Race Car |

I went to the track this weekend and these are my notes:Well handling is defiantly better with the rear konis on the heavyest setting. She is now trypoding majorly - but I am not sure if that is a good thing. With it trypoding I am finding the rear way more unstable. She is still fairly predictable but it does not feel even 80% of what I want it to feel like. Next step will be to upgrade all the bushes to urethane and maybe solid mounts and see how she goes. The linkage also came of the ball joint on a small off so will also need to address this - it was easy to pop back in but had to get towed back to the pits and don't what this to happen again. |

Stiffer anti roll bar and torsion bars should eliminate the tripoding I'd have though. The solid mounts just stop the passive steer which is a trait I really rather like. ________________________________________ See the sheer power and might of the lesser known burrowing owl. |

My logic would be that it would actually make it tripod more as there would be less 'roll' so will lift the other wheel more easily. ________________________________________ Ryan |

But with less roll on a flat road could it still clock a leg as it shouldn't be rolling. Well, that was my thinking. I could be wrong though. Often am infact.  ________________________________________ See the sheer power and might of the lesser known burrowing owl. |

unless you stiffen up the front corners it will still roll and tripod, though the rear ARB will decrease the amount it does it at by increasing rear slip.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

Im going to stick to what i said in the beginning in that you have a standard ish back end with a mega stiff front. You need to stiffen the back to help keep the front on check other wise you will always have understeer.________________________________________ Ex- Phase 3 China GTi-6 T-Reg |

If you're still getting terrible understeer try disconnecting the front ARB (without removing the whole thing you can just take out one of the drop links so you can just put that back in if you don't like it). If you've stiffened the front you'll be getting less roll than a standard set up during cornering and so the extra roll stiffness the ARB is providing will make it understeer more. ________________________________________ Ph1 306 GTi 6 | RX8 231 S1 | YBR 125 Cafe Racer | MT-03 660 |

It's overly soft springs and an undersized front ARB you need to sort if you want to lessen/eliminate the front end dive & roll that unloads the inside rear and reduces the outside front tyres contact patch all at the same time (not a winning combination) increasing the front track (wider wheels/spacers/longer wishbones etc) will help to reduce roll induced under steer but springs and ARB is where you need to put your money. ________________________________________ R H Davey Welding Supplies.
