Member Jonathan Kay Posted August 31, 2023 Member Share Posted August 31, 2023 Which wheels and axle? Please add a photo if you aren't sure what they're called.Full search of the archives, but I'll narrow that down when we know the wheels.Discussion of required length.Jonathan Link to comment Share on other sites More sharing options...
Wrightpayne Posted August 31, 2023 Share Posted August 31, 2023 On my '98 dedion (Ford fitment wheels) I run Mk1 Elise open end wheel nuts - mentioned in some of the results in Jonathan's search. Link to comment Share on other sites More sharing options...
jody391 Posted August 31, 2023 Author Share Posted August 31, 2023 Sorry guys it's a 2005 on KN 13 wheels with Didion axleits and ex academy car if there are any differences.also whilst on the wheel but topic, torque settings at 75nm seems really low! My Elise was 85nm which again always seemed low?on the A52 coming back from a drive over Grantham way the road is concrete and in sections, when I got back I checked the car over (one of my first drives out) and the wheel nuts were loose!

Member Jonathan Kay Posted August 31, 2023 Member Share Posted August 31, 2023 "also whilst on the wheel but topic, torque settings at 75nm seems really low!"Yes, 75 Nm.And the low value has been questioned before. : - )Jonathan Link to comment Share on other sites More sharing options...
ScottR400D Posted August 31, 2023 Share Posted August 31, 2023 I think you'll find CC now recommend 85Nm. Link to comment Share on other sites More sharing options...

7 wonders of the world Posted August 31, 2023 Share Posted August 31, 2023 on that year its also worth checking you have the longer wheel studs, my previous 2006 car had long ones on the uprated front hubs but short ones on the rear.Studs lengths are 47mm long (ideal) length, whilst the original short ones which offer insufficient thread engagement are only 40mm this equates to 28mm or 21mm of thread protruding from the hub / flange.

SM25T Posted August 31, 2023 Share Posted August 31, 2023 Short ones are useless for alloy wheels. Suspect they were originally used for pressed steel wheels, and never changed. When we got our car, the 32mm studs allowed nuts to engage by about 3 turns. I argued this was a dangerous engineering practice, as nuts should be fully engage. CC wouldn't have it. I replaced all studs with 40mm, and it left a bad taste for ever. Link to comment Share on other sites More sharing options...
Drakman Posted August 31, 2023 Share Posted August 31, 2023 Hi Jody, I got some Titanium open ended wheel nuts for my 2014 roadsport. Thread is 12 mm x 1.5, 60 degree taper.The Titanium wheel nuts are half the weight of the std steel short Caterham wheel nuts. If you want some look on ebay.com, the US version. I believe the nuts i have are from a Chev Camaro, sorry i don't know the model year.Cheers Link to comment Share on other sites More sharing options...
jody391 Posted September 1, 2023 Author Share Posted September 1, 2023 Can you change the studs without removing the hubs? Link to comment Share on other sites More sharing options...
7 wonders of the world Posted September 1, 2023 Share Posted September 1, 2023 No sadly not, you need to pop the disc off the hub once its removed support the flange and a swift blow from a knocking stick get the old ones out. Link to comment Share on other sites More sharing options...
JP Posted September 2, 2023 Share Posted September 2, 2023 Here's a comparison of thread engagement with long studs and short ones with open ended nuts: Link to comment Share on other sites More sharing options...
Wrightpayne Posted September 2, 2023 Share Posted September 2, 2023 Thats shockingly poor - all hidden with the std chrome wheel nuts Link to comment Share on other sites More sharing options...
SM25T Posted September 2, 2023 Share Posted September 2, 2023 Exactly how it was for me, yet CC said it was acceptable Link to comment Share on other sites More sharing options...
JP Posted September 3, 2023 Share Posted September 3, 2023 #15 - I know - guess how annoyed I am that I forgot to do the fronts when I had the hubs off... Link to comment Share on other sites More sharing options...
