Gloucestershire AR Posted January 15, 2016 Share Posted January 15, 2016 Can't find anything previous on this using search but what's the current thinking about lightweight wheel nuts?I run Caterham 8 spoke anthracites (Ford fitting but live axled car) and fancy some nice aluminium ones. Is that a good idea? Currently have big heavy closed top chrome thingies.The locking wheel nuts are already open top and non-chrome.Thanks all.Andy Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted January 15, 2016 Member Share Posted January 15, 2016 IIRC the last time it was discussed it was thought that the uncertainty about them remaining intact and in place outweighed (!) the saving in mass and rotational inertia.Yes: threads from 2011 and 2003.

Gloucestershire AR Posted January 15, 2016 Author Share Posted January 15, 2016 That makes sense, thanks Jonathan. Using ali nuts on steel bolts I guess could give rise to different expansion rates? As a long time Le Mans attendee, I'm reminded of all the three wheeled cars I've seen over the years after the (ali) nut had departed from the (steel) hub. Most of the ali nuts on ebay seem to come from China and certainly look smart but not sure that's what should drive my decision here...Andy Link to comment Share on other sites More sharing options...
Drumster Posted January 16, 2016 Share Posted January 16, 2016 Hi Andy, Nowt wrong with the stainless steel nuts and washers from CC. Had a set for the last 8 years and they still look good as new Link to comment Share on other sites More sharing options...
LesG Posted January 16, 2016 Share Posted January 16, 2016 I think your money would be better spent elsewhere, with more reliability and safety. I use standard Ford open end nuts with connected rotating washers, cheap as chips from any dealership (ask and they may give you some for free as they replace plenty with locking versions), they can't be that heavy, and it's easy for a scrutineer to see how many threads are engaged.

TomB Posted March 15, 2017 Share Posted March 15, 2017 Picked this thread to resurrect as its fairly recent.I need some shallower wheel nuts for my 1996 dedion car so I can fit the wheel nut covers on my SLR wheels. Do these look like they will be suitable?http://www.ebay.co.uk/itm/16-x-Ford-Fiesta-M12-x-1-5-19mm-Hex-Open-Alloy-Wheel-Nuts-Silver-/182107290640?fits=Car+Make%3AFord%7CModel%3ASierra&hash=item2a6670bc10:g:FFEAAOSwUKxYfiYMMy set of closed wheel nuts do not have washers. Should they? Link to comment Share on other sites More sharing options...
Wrightpayne Posted March 15, 2017 Share Posted March 15, 2017 I have some lotus elise series 1 wheel nuts that look very similar but in black. Mine have a 60 degree taper. One of the elise spares companies will stock them. After 5 ish years use no rust.Ian Link to comment Share on other sites More sharing options...
pikeyboy Posted March 16, 2017 Share Posted March 16, 2017 The MSA don't allow the use of aluminum wheel nuts on race cars which should tell you all you need to know. My old 968 CS had ali wheel nuts as standard and I never felt comfortable nipping them up if I'm honest. I use std ford open nuts on the seven and i doubt you'll notice any weight benefit, you'd probably be better spending the cash on a half hour tuition session with an instructor.

Dorset7 Posted March 16, 2017 Share Posted March 16, 2017 I've been using ali wheel nuts on the 7 for an age and never had an issue with them coming loose.I've done plenty of miles in one hit (to include motorway and cross country blatting) without trouble.
