Leadership Team Mcalvert Posted March 20, 2003 Leadership Team Share Posted March 20, 2003 I was about to order some new wheel-nuts from Caterham becase after a few years, the chrome has come off and they're pretty rusty now. However, it got me thinking that they're pretty heavy, unsprung weight, so I'd quite like to get some open nuts which would look groovy and possibly be a few micro-grams lighter ❗ Anyway, I don't know if there is a particular pattern or spec to look for to fit securely on a 13" wheel - what should I be asking for please? Thanks - Michael. Link to comment Share on other sites More sharing options...
philwaters Posted March 20, 2003 Share Posted March 20, 2003 Didn't Arnie run some light Alloy wheels nuts? They would be nice and light... Otherwise, just make sure that the thread depth/length is at least 1.5 times the thread size (M12 if De-Dion) so 18mm. Phil Waters You mean you can drive these? I thought it was just there to polish 😬 Link to comment Share on other sites More sharing options...
Leadership Team Mcalvert Posted March 20, 2003 Author Leadership Team Share Posted March 20, 2003 So is the shape and angle of the Chamfer standard on all wheel nuts? Thanks - Michael. Link to comment Share on other sites More sharing options...
Lee Posted March 20, 2003 Share Posted March 20, 2003 James Whiting showed me some stupidly light wheel nuts for the Fireblade a couple of weeks back... think they were about £2.50 each. Give him a call to see if they are suitable. Gonna have to get some in the next couple of weeks for my Fireblade! Link to comment Share on other sites More sharing options...
elie boone Posted March 20, 2003 Share Posted March 20, 2003 Wheel nuts chamfer ( Ford ) are 60° like on most cars. Link to comment Share on other sites More sharing options...
Tight fart Posted March 20, 2003 Share Posted March 20, 2003 £40 for nuts, you must be 😬 Link to comment Share on other sites More sharing options...
stevefoster Posted March 21, 2003 Share Posted March 21, 2003 Hmm, Beware some nuts have poor threads. Ali nuts... I would not use them on wide slicks. The MSA requires steel nuts I believe and scrutineers require to be able to check the depth the stud goes into the nut. Some of the Caterham studs a pretty short and if you swap wheels from the supplied ones check the depth. At least 1.5 X the stud diameter should be into the nut, ideally more. I put longer studs on and use open race wheel nuts. My racing pics, 7 DIY, race prep.

Nigel Riches Posted March 21, 2003 Share Posted March 21, 2003 As you say you want to save a few micrograms of weight why not just let the natural process of plating falling off and steel nuts reverting back to the lowest atomic number to achieve your desired goal?, won't look tidy, but you wont have to do anything to ensure the process continues, just jossin', Nigel. 1982. 5 speed, clamshells.

Trevor Phillips Posted March 21, 2003 Share Posted March 21, 2003 Where in the Blue Book is the steel only reference? I cna't find it. Racing pics and items for sale here Link to comment Share on other sites More sharing options...
KevSull Too Posted March 21, 2003 Share Posted March 21, 2003 Can't you run on just two nuts per wheel - 50% weight saving straight off!!! (Disclaimer: Don't try this at home children.) 😬You laugh at me because I'm different, I laugh at you because you're all the same. 😬 Link to comment Share on other sites More sharing options...
stevefoster Posted March 21, 2003 Share Posted March 21, 2003 Trevor. J 20.7.2 Have all nuts securing road wheels, excepting those of centre lock type, of steel and in thread contact of a minimum length of 1.5 bolt/stud diameter. Extended or composite wheel bolts/studs are prohibited. Cars of periods A to D are exempt from this requirement. My racing pics, 7 DIY, race prep.

stevefoster Posted March 21, 2003 Share Posted March 21, 2003 Yeah. I was thinking Colway F2 cut slicks for wets and then saw that Remoulds are prohibited too. I am sure Colways are remoulds aren't they...? My racing pics, 7 DIY, race prep.

Trevor Phillips Posted March 21, 2003 Share Posted March 21, 2003 I think their whole range is remoulds. I bought slicks last season from George Polley and he hand cut them into wets. Racing pics and items for sale here Link to comment Share on other sites More sharing options...
