Wrightpayne Posted July 11, 2023 Share Posted July 11, 2023 I have these on my seven.....mk 1 Lotus Elise wheel nuts. There are posts in the archives on the subject.https://www.eliseparts.com/shop/wheels-and-tyres/nuts-bolts/19mm-hex-open-ended-black-wheel-nuts/ Link to comment Share on other sites More sharing options...
PlastererPete Posted July 11, 2023 Share Posted July 11, 2023 #2, they are considerably cheaper than the H&R ones I was looking at on performancealloys.com.Any idea who makes the ones you've got? Link to comment Share on other sites More sharing options...
Wrightpayne Posted July 11, 2023 Share Posted July 11, 2023 I've no idea but been fine for 10+ years Link to comment Share on other sites More sharing options...
Andy Tims Posted July 12, 2023 Share Posted July 12, 2023 Those look good. Are they lighter than the OEM ones? Link to comment Share on other sites More sharing options...
Wrightpayne Posted July 12, 2023 Share Posted July 12, 2023 Marginally, as they are shorter due to being open ended - a feature I was keen on so I could see they were on fully.The early ford hub cars (mine is 1998) had short studs where the threads only engaged 5 turns. The engineering acceptability of this was debated on the forum many years ago and the general consensus was it was borderline.At some point in production (early 2000s ????) a longer stud was introduced by Caterham. I retro fitted them.An FYI for new members!! 5 turns to tighten then you have the short studs.Ian Link to comment Share on other sites More sharing options...
Wrightpayne Posted July 12, 2023 Share Posted July 12, 2023 The black open wheel nuts are 15.75g lighter than a full closed chrome wheel nut (caterham supplied) so 252g lighter on a set of 16 Link to comment Share on other sites More sharing options...
BigCol Posted July 12, 2023 Share Posted July 12, 2023 I have these on my car... Link to comment Share on other sites More sharing options...
PlastererPete Posted July 12, 2023 Share Posted July 12, 2023 Bought a set from eliseparts today. Emailed them and asked who makes them and its the same supplier who supplies Lotus direct. They are 10.9 grade too. Saved me a fair chunk of money over the H&R ones I was going to get. Link to comment Share on other sites More sharing options...
Leadership Team Mcalvert Posted July 12, 2023 Leadership Team Share Posted July 12, 2023 For what it's worth, Motorsport UK's definition of safe engagement of wheel nuts is that they must be "in thread contact over a minimum length of 1.5 bolt/stud diameters". (Guess who got pulled up on this when I was slightly borderline a few years ago...) Link to comment Share on other sites More sharing options...
7 wonders of the world Posted July 12, 2023 Share Posted July 12, 2023 guessing you had the ridiculously short studs CC fit...? Link to comment Share on other sites More sharing options...
Wrightpayne Posted July 12, 2023 Share Posted July 12, 2023 Used to fit - longer ones are standard now!!!I fitted some uprated front hubs last year and they came with the longer studs Link to comment Share on other sites More sharing options...
Drakman Posted July 13, 2023 Share Posted July 13, 2023 I was lucky enough to find a set of Titanium wheel nuts, these weigh 31 grams, half the weight of the standard items. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted July 13, 2023 Leadership Team Share Posted July 13, 2023 For 12mm studs the minimum length would therefore be 18mm, definitely more than the 7.5mm that would be achieved with 5 turns of 1.5mm pitch threads! The Elise parts nuts are 25mm long Link to comment Share on other sites More sharing options...
7 wonders of the world Posted July 13, 2023 Share Posted July 13, 2023 Good point Ian,My previous 2006 car had long ones on the front upgraded hubs but short ones on the rear..... Wonder what year CC got things aligned...? Link to comment Share on other sites More sharing options...
Graham Hutton Posted July 13, 2023 Share Posted July 13, 2023 oooo! Where did you get the titanium ones? I'd be up for a set of them! Link to comment Share on other sites More sharing options...
rj Posted July 13, 2023 Share Posted July 13, 2023 And if the titanium nuts were available for MB wheels ... MMmmmm Link to comment Share on other sites More sharing options...
Drakman Posted July 13, 2023 Share Posted July 13, 2023 Haha, I had heard stories about English drivers and their "special" interests, oh, you meant my titanium nuts?I don't want to upset the purists out there but they are from a Chev. I got them from the good ol US of A,via ebay. Cost to me was $87 dollars plus post to Australia for 20 nuts, 5 per wheel for Chev. I figured 12 x 1.5 with a 60 degree seat was right for my Caterham, what could go wrong, in fact nothing did. They fit like they were made for the Caterham.I could quite easily cut these in half for my fitment, the last 1/2 inch is just to allow a socket to grip them in deep dish wheels. Inside the last half inch is a rubber seal to keep crap out of the threads.The first thing you notice is how light they really are, my first thought was the thread will just pull out!
