kosmic Posted May 24, 2008 Share Posted May 24, 2008 Am i right in thinking that a low offset wheel i.e. et35mm will give better caliper clearance than a higher offset wheel i.e. et50mm?? Just spoke to elite alloys who said that is correct but its difficult to get my head around as im not sure whether the backspace of the wheel is adjusted or the mounting face is increased/decreased to adjust offset on wheels?? any help please??

Nic Posted May 25, 2008 Share Posted May 25, 2008 Yes +35 offset will give more brake caliper clearance than +50 offset. http://www.tirefactory.com/img/offset.gif Quote Link to comment Share on other sites More sharing options...
kosmic Posted May 25, 2008 Author Share Posted May 25, 2008 thank Nic, any idea of what kind of offset is needed to clear brembo 4 pots assuming the width is 8.5"?? (from surface of disc to face of caliper depth is 57mm) Quote Link to comment Share on other sites More sharing options...

(from surface of disc to face of caliper depth is 57mm) Which wheels, it will vary depending on the wheel design? Brembo should have a cross sectional diagram of the calipers available which will help work out the offset needed. Quote Link to comment Share on other sites More sharing options...

Nic Posted May 25, 2008 Share Posted May 25, 2008 Which Brembo brakes do you have fitted? If you let me know disc size and caliper model I'll send you a template. Quote Link to comment Share on other sites More sharing options...

If i use hubcentric spacers then they will protude outta the arches and look shite BUT if i get them in et45mm and then use hubcentric spacers to clear the calipers, they should sit nice and flush. not sure whether wheels are machined on the mounting face side to adjust offset or the whole spoke assembly is moved in or out?!
