I see already sounds complicated haha will be in touch soon !

Sorry havent got back sooner busy with work and all that Tony have checked all mechanicals and everything is in order. The car has had new boots fitted on front and complaint existed before this. Alignment was done but just front toe angles and even then was only marginally out. Pete thanks for the info also and is looking like will maybe have to go down the Honda route, hopefully they can shed more light on the issue. Thanks once again! PS Tony have brought myself a Lexus IS300 sportcross, only 48k genuine miles bagged a bargain off ebay haha am impressed, anything to be aware that you know of? will update profile pic accordingly the beast has now gone

Morning all! Wondering if anyone can possibly shed some light here....Honda Jazz which has had the geometry checked and adjusted (only adjustment needed being front toe) all other angles including the solid rear axle being well within spec, but the complaint being that the steering doesnt self centre? Have driven the car myself and wether at slow or higher speed once steering is applied if its not forced back into a central position it will continue turning, which could be handy if you enetered a roundabout you didnt want to leave :S Anyway if there are any ideas as to why this might be would be appreciated Many thanks!!

To be honest i think is a combination of both being out, is worn in a sloped fashion treads ranging from 0 on inside to about 6 on outside. (if was specifically camber wear is generally confined to a small part of tyre ie shoulder area?) done a test on geometry which gave some pretty interesting readings. What "interesting readings"? Tony sorry havent got back for so long, unfortunatelly this car resulted in replacing front tyres and we never got a chance to recity the geometry issue, (went to Porsche for setup) the interesting readings were that originally when car came in the front cambers were within spec but when it came back had both fallen apprx -.25 degrees and caused that amount of wear?? seemed a bit strange to have caused the amount of wear it had!

Apparently the handling can become a bit sloppy if you change from run-flats to normal loading tyres, dont they set the suspension to compensate for the reinforced sidewalls of runflats?

I feel sorry for anyone with runflats who doesnt realise what they have. Like you say dud after a puncture and horrible to drive on. One thing though with all the potholes, has anyone else noticed all the speed humps that seem to be popping up all over the place, perhaps use the tarmac from them to fill holes instead...??? just an idea but what do i know lol!

Thanks again Tony turns out that the rear end of the car was quite possibly put on one large axle stand(on the beam) whilst on a 4 poster for a tyre change. Unhappy customer me thinks

just seen a renault megane convertible, both rear tyres worn on outter edges both as bad as eachother. Any ideas why this is happening, im presuming ride height isnt optimal as there isnt any form of adjustment on rear?

Hi again Tony, am hoping you can help but had a Porsche I set up quite a few months ago now (October time ish) which has scrubbed insides of both front tyres. Am yet to see the car so am going on customers descriptions here. Apparently both rears fine only fronts. i know for certain that the vehicle was setup to manufacturers settings (your probably cringing already). Since setting this car up I have continued to try and learn as much as i can about geometry setups and came to the conclusion that setting the front wheels to manufacturers settings on a high performance rear wheel drive car is a bad idea due to the forces exerted on the front wheels whilst under load (not static) which if im thinking right gives the front wheels a toe out whilst moving explaining the inside tyre wear? so to resolve this problem would setting the front wheels to a slight toe in from manufacturers settings give a closer to desired result and if so how much is acceptable. :angry:

I wonder if they charged him more for how many weights they had to use lol

Thanks Tony, this is roughly what I thought just wanted to confirm with someone. Thanks again!

Hi all, just needing a bit of advice on Geometry setups for Porsches. Can anyone shed some light on correctly setting up the rear toe and camber angles, ie is it a case of a combination of the 2 control arms on the rear both being used to achieve manufacturers settings where as in most cars you have a dedicated camber/track control arm. I have recently setup a Porsche 911 996 and noticed that the control arms dont just change one specific geometry angle I had to fiddle with both of the adjusters to achieve tolerance. If anyone can shed any more light on exactly the correct procedure for setting these up would be helpful. Thanks in advance James
