StewartG Posted February 9, 2001 Share Posted February 9, 2001 Does anyone know which of the many front geometry parameters causes the inside edges to wear or is this normal if not exessive? Link to comment Share on other sites More sharing options...
Dave M Posted February 9, 2001 Share Posted February 9, 2001 Negative Camber. If you have it set for track ie. 1.5ish negative and you do a lot of road miles, then the inside edge of front tyres will wear. Just drive harder and the wear will even out. smile.gif Dave Link to comment Share on other sites More sharing options...
Graham Sewell Posted February 9, 2001 Share Posted February 9, 2001 If the driving is mainly in a straight line (not Seven like) then camber is the worst culprit. Otherwise is can be any of them. Cheers, Graham Link to comment Share on other sites More sharing options...
EFA Posted February 9, 2001 Share Posted February 9, 2001 err Toe out??? You should have about 0.5 - 1mm toes on max on the front end. Even with lashings of neg camber (like 3 or 4 deg) the inside edges do not wear so badly. This is not however true for the rears which do wear significantly on the inside edges if you use 2 deg ears.

Arnie, it all depends on how fast you corner and how many doughnuts you do! smile.gif Alex Link to comment Share on other sites More sharing options...
Graham Perry Posted February 10, 2001 Share Posted February 10, 2001 As Arnie says, also check you haven't got toe out. Parallel or slight toe in is the norm for a Seven. Link to comment Share on other sites More sharing options...
EFA Posted February 10, 2001 Share Posted February 10, 2001 Graham, I found on my car that there was more feel and less tramlining with things set between parallel and slight toe out..... Alex, this theory is based on pre-doughnut era driving...... If you drive normally the wear should be pretty even. Track days and very fast road driving will tend to wear the outside edges of the fronts......

Graham Perry Posted February 10, 2001 Share Posted February 10, 2001 In my youth I deliberately adjusted the tracking on that days set of wheels to lots of toe out (couldn't measure it) to see what it would do. .......... wore the front tyres down to the canvass in a mornings driving,You could see all the rubber stuck inside the wheel arches all on the inside of the tyre. Lesson learned, so then I tried lots of toe in.................. My findings were that Lots of toe in and out are equally as frightening. I guess I didn't have enough to do in those days.

StewartG Posted February 10, 2001 Author Share Posted February 10, 2001 Upon reflection and having absorbed the wisdom herein I suspect there's not too much wrong with my geometry. I notice on track days it's the outside edges that wear and recent mileage has been on the road and the inside edges look worn. It's just time for another track day except they all seem to be in foreign countries like Wales at the moment. Link to comment Share on other sites More sharing options...
