| Post subject: | ride height question |
when getting a wheel alinement as far as hi lows go & ride height would you have the drivers side slightly higher then the passenger? as you do all your driving that side? or same all around? does the ride height effect the wheel alignment much? I heard it can give it more positive? is that true? |

The higher the ride height, the more postive the camber. As for RHS v LHS bias, I would not be too concerned about driver mass effect on handling for normal road use. More relevant is the affect of excess weight on the car's power to weight ratio. To that end I myself have been intending, for the last 20 years, to go on a diet. I am certain my Cooper S was much faster when I was just 21.

My motorbike mechanic always has a laugh at blokes spending thousands of dollars on lightened go fast carbon bits and pieces when they actually need to just lose their middle age paunch!
I suck my gut in every time I go there now! That's a fascinating question about whether the driver's side should be set a tiny bit higher. What do other people think? I'm looking at putting coil springs in my resto with hi lo's. Have many people had experience with these? |

We used to put a couple of mm into a race car to get the corner weights spot on with me in it but it really makes stuff all difference |

We get the same thing in the pushbike trade.... Guys looking to shave every last "excess" milligram from the bike, when they would gain so much more benefit by carving several times the bike's weight from themselves. |

if you change the ride height, then you have changed the wheel alignment settings in the process. & the changes in wheel alignment that come-about from the change in ride height-> depend on where the car was set in the first place... but it don`t really matter much because simply put--> if you lift the car up, then you have changed the wheel alignment if you lower the car, then you have changed the wheel alignment simple as that i generally add 5mm (higher) to the drivers side "IF" there is "Normally" only one person in the car at "Most" times...(((depending on the weight of said person))) edit--> minis (& nearly all cars) have some built-in Bump steer that causes a pile of problems with regard to the toe-changes that occur when changing ride heights,,, the camber & caster also go through a swing of changes as the suspension raises & lowers Morris Marinas for a really good example (or rrather i should call that a very bad example as the case may be) they swing horribly wrong as the suspension raises & falls they`re the worst i`ve ever seen however, i went to great lengths (when i built my buggy) to make sure that my buggy does NOT change the toe-setting during suspension swing/travel (up & down movement) this is commonly called "Zero-Bump-Steer"... but the camber does change a little bit & that`s a good thing in this case cause it changes the way i want it to... but most cars will change both toe & camber quite a fair bit throughout suspension travel |

Spot on Matt. I saw in the CAMS regs for nb minis that moving suspension pick up points to a set limit is allowed. Do many of the front running cars actually have revised geometry?? I think you once mentioned slightly repositioning the rack to reduce bump steer. M |
