| Post subject: | cutting Suspension trumpets |
So is this a legitamet (sp) was to lower a dry mini? I would like to do this on my 74 Clubby (obviously dry). I have heared that it is not good to do this, but if using the correct measurements from Vizard, is there anything wrong with doing this? I would fit Hi-Lo's but i dont have the money,,, and this car has got to drop some

Have you got a lathe? You'd only be removing about 5mm tops I'd imagine. Much more and you'll need spacers again. |

I've found it to be safe , just make sure you double check the measurments and ratio's as they are different for the front and rear , just can't remember off hand . One was 1:5 (front?) I think and the other 1:3 ? In other words for evey inch you cut off that's how far the suspension will drop , a little cut will make a big difference to height so make sure you get the measurments formo a reputable source , if you're using Vizards info then you should be right . |

thanks mate! Its just once i was contemplating doing this and someone said that it is not a good way as it stuffs up the suspension and that Hi Los were much better, But the way i see it. it is basiucally the same principal. you either have a short metal bar (hi lo) or a short trumpet.. no real difference? |

And remember , you'r only cutting 1/4" or so off anyway , not actually weakening it . All I'd suggest is to choose a cooler method of cutting it off , with a hacksaw or on a lathe as opposed to a grinder with a cutoff wheel . |

It's the other way around- fronts are 1:3 and rears 1:5.

thanks. So is it worth cutting the front also? im not replacing the cones. so they may be flat from the engine. how much does it lower the car. I dont want it to be riding on its bump stops |

I've seen what happens when somebody decided to lower a mini all round by two inches , removed all 4 trumpets while the car was on stands and cut two inches of each trumpet before refitting them all ....  Bump stops all the way around  ...

Just check that there isn't some spacer washers on your knuckle joints already you might not have to cut anything off
There was also a bit about lowering minis by cutting the trumpets on minimania's website here we go this looks like it: http://www.minimania.com/web/SCatagory/SUSPENSION/DisplayType/Calver%27s%20Corner/DisplayID/1231/ArticleV.cfm |
