Julian73 Posted September 10, 2019 Report Share Posted September 10, 2019 Has anyone had a failure of a rear Toe Link? Details if so. Quote Link to comment Share on other sites More sharing options...
B430m Posted September 10, 2019 Report Share Posted September 10, 2019 I thought that was only a problem with Elise/Exige cars, never heard of it on Evoras. Whats the Mark on the adjusting nut, has it been hit with something? Quote Link to comment Share on other sites More sharing options...
Colin P Posted September 10, 2019 Report Share Posted September 10, 2019 It does rather look like it was banana shaped before it snapped - perhaps suggesting an impact of some kind. The threads below the break also seem to be distorted (closer together on the right than the left). Quote Blessed with the competence to be a slave to the incapable. Currently without a Lotus, Evora 400 Hethel Edition in Racing Green with Red leather and 2010 Evora N/A in Laser Blue and 1983 Lotus Excel LC Narrow body in Ice Blue all sadly gone.

I wonder if there is an increased loading with the change of tyres on later models? Quote Link to comment Share on other sites More sharing options...

Gold FFM C8RKH Posted September 10, 2019 Gold FFM Report Share Posted September 10, 2019 Ouch! Hopefully @spitfireengineering will have an Evora upgrade kit like they do for the VX, Elise and Exige? Quote Alcohol. Sex. Tobacco. Drugs. Chocolate. Meh! NOTHING in this world is as addictive as an Evora +0. It's not for babies! The first guy to ride a bull for fun, was a true hero. The second man to follow him was truly nuts! Link to comment Share on other sites More sharing options...

Julian73 Posted September 10, 2019 Author Report Share Posted September 10, 2019 (edited) I'm not so much asking for an analysis of my break, I head an engineering team of structural, mechanical and metallurgical engineers, bt rather have any others seen this. Yes the aftermarket provides an alternative, but I always assumed that it was from a desire to create a market based on Elise/Exige fears. Yes, the threads were bend at a 28 deg angle, thus why i laid them out that way Yes, impact loading was involved Yes multi cracks formed at various times i)fatigue, ii) compression, iii) tensile No, the "mark" is irrelevant as it is most probably a tool slip on the nut. No measurable reduction in area, thread material is typically heat treated to very high yield and tight yield to tensile ratios thus little ductility Don't see that todays OEM tires are a cause as theses cars back to the Series 1 have been tracked with R compound tires including semi slicks Hoosier A7, design and part numbers of the suspension arms and links are the same since Series 1.

Bruss Posted September 10, 2019 Report Share Posted September 10, 2019 Thanks Julian. Just trying to get a handle on what's happened. I track mine on cup 2's and haven't seen any sign of this but I havent done a DP test. I did look at the spitfire links and decided I would change mine out at some time, probably at my next suspension refresh. Quote Link to comment Share on other sites More sharing options...
Julian73 Posted December 19, 2019 Author Report Share Posted December 19, 2019 Replaced OEM toe links with Spitfire Engineering's Version 2 (sold by HethelSport in the US), these move the turnbuckle to the outer end of the rod, while increasing the thread diameter and going to a large diameter hollow tube aluminum rod rather than a thinner steel forging. (last photo curtsey of #HethelSport) 1 Quote Link to comment Share on other sites More sharing options...
21gg Posted December 19, 2019 Report Share Posted December 19, 2019 Ive only seen that once and it was due to a wheel impact. Quote Link to comment Share on other sites More sharing options...

mg4lotus Posted December 18, 2021 Report Share Posted December 18, 2021 I have to replace a broken rear tie rod and have a few questions. Do I go with the original at £100 or do I go with the Spitfire engineering upgrade at considerably more? If I choose the upgrade do I have to do both sides or can I just replace the broken one? The upgrade is lighter and stronger. I wouldn't notice the difference if it was lighter (apologies to ACBC). It is stronger, is the original part designed to be sacrificial to protect the bits that it connects to? Delivery timescales may be the deciding factor as I want to drive my Lotus. Does anybody have experience of sourcing this part? Quote Link to comment Share on other sites More sharing options...
Whitey Posted December 18, 2021 Report Share Posted December 18, 2021 I’d definitely fit the Spitfire ones on both sides. How did the failed one break- curb strike or pot hole? 2 Quote Link to comment Share on other sites More sharing options...

DarrylV8 Posted December 19, 2021 Report Share Posted December 19, 2021 Hi Mark, i would also say replace both OE items with the Spitfire units. Try Seriously Lotus in Hull. 2 Quote Darryl & Sue Proud to drive and own since new a true British supercar the Evora GT430 Link to comment Share on other sites More sharing options...
