Bristol Red Posted May 13, 2010 Report Share Posted May 13, 2010 Hi All I have had a set of Powerflex poly bushes fitted in the rear subframe of my ST220 since around 40k miles and recently found out that Powerflex now also do poly bushes for the front wishbones with the rear bush also having castor adjustment built in. http://www.powerflex.co.uk/products/Mondeo...%29-2410/1.html Anybody had any experience with these yet? The reason I ask is that I have been suffering from front tyre wear on the inner shoulders on my ST220. I visited WIM back last year and had my geometry set up (front subframe had to be moved forward) Had a new set of tyres fitted and since then the wear has dramtically reduced but is still there. Wheels are std 18" alloys, the suspension is standard and car has now done 60k so I was thinking of replacing all the front suspension bushes to eliminate any wear and tighten things up.

Rich Posted May 13, 2010 Report Share Posted May 13, 2010 Link not working, is it these - Click here Strange they're for castor and not camber as the wear would be caused by the later, the former is more about the stability of the car (I think). I'd imagine they would only fit genuine arms though, do you still have these? Quote Link to comment Share on other sites More sharing options...
Bristol Red Posted May 13, 2010 Author Report Share Posted May 13, 2010 Yes that's the ones.. just sorted my link! Car still has the original wishbones fitted to it but was going to get a spare set and make them up beforehand with new ball joints as well. I was told when the guys did my geometry that the inner shoulder problem was related to castor and that's why they had to move the front subframe forward?? So was thinking that maybe these adjustable bushes would help also.. or am I going in the wrong direction? Quote Link to comment Share on other sites More sharing options...
Tony Posted May 14, 2010 Report Share Posted May 14, 2010 How far was the castor out? reason i ask is these only allow for 30' of adjustment. Quote Link to comment Share on other sites More sharing options...
Rich Posted May 14, 2010 Report Share Posted May 14, 2010 How far was the castor out? reason i ask is these only allow for 30' of adjustment. Tony, does castor have an affect on tyre wear then cos that's the first time I've heard it being associated with it? Quote Link to comment Share on other sites More sharing options...

Hi Tony.. unsure of what it was before the adjustment was made but I still have the finished print out if that helps. I will scan it and post it up later on Andy Quote Link to comment Share on other sites More sharing options...

Gonna need an explanation for that one :closedeyes: Quote Link to comment Share on other sites More sharing options...
Bristol Red Posted June 7, 2010 Author Report Share Posted June 7, 2010 OK sorry for the delay but finally found the print out so scanned it earlier and here it is. Car has done around 8k since adjustments were made and I also had new tyres fitted at the same time which now need replacing due to wear on inner shoulders as they are now bold Any advice much appreciated before another pair of tyres go on for the up and coming M.O.T Thanks Andy Quote Link to comment Share on other sites More sharing options...
Tony Posted June 7, 2010 Report Share Posted June 7, 2010 Looking at the print, half a degree is all you need. Quote Link to comment Share on other sites More sharing options...
Bristol Red Posted June 7, 2010 Author Report Share Posted June 7, 2010 Looking at the print, half a degree is all you need. What would you recommend then Tony? I presume with the subframe moved forward there is no other way of increasing this another half a degree.. would it be worthwhile fitting the adjustable poly bushes to the wishbones and getting another geometry set-up done?

Since the problem is ongoing i would say yes, adjust ability is the answer. Quote Link to comment Share on other sites More sharing options...
