I have lots of comments on GTS tuning and Darren George none of which I can put on this forum or any other! If it was my money that I was spending I would look at other suppliers even my immediate competion.

The reason they are offset is to align the top and bottom pivots with the axle centre line better, If you draw an imaginary line through the Sierra upright you will see that if the mushroom insert is concentric it will miss the centre line of the axle, requiring more effort to self centre.

The reason some suppliers mushrooms are concentric is cost, put plain and simple they are cheaper to make.

Hope that all make sense

Kind regards

John

This has all been done before you need offset mushrooms for the best geometry with sierra uprights.
gts will tell you anything to get a sale .
its all to do with kingpin inclination
there is a search tool on this forum
and yes you do want both sides the same thats why when i made my offset mushrooms i marked them with a file to show the position of max offset

Sorry I didnt mean to sound rude
ask away thats what were here for
had a quick look there used to be a thread all about the offset but appears to have disapeared
what i meant was sometimes its quicker to search than to ask as most of the answers are there already
seems this one got taken by the hacker

Dont qoute me on this but I think anti dive was mentioned that is built into the Sierra front geometry and the combination of the offset mushroom and the way the Roadster setup works corrects it all ie kpi/castor angles camber self center etc.
And again no quoting but people have had problems using central holed mushrooms,because of the self center requirement in the IVA.
