Can you tell if my toe link nuts have been upgraded?
 
2 Attachment(s)
I am a relatively new Elise owner (purchased mine in July 2018), and while I had the car lifted, I checked the rear toe link nuts (as is highly recommended on these forums). My wrench clicked with no movement, when set to 44 ft-lb, so mine are good to go for now. I am wondering if someone on here can look at these pictures and tell if my toe link nuts have been upgraded already? Thanks!

In terms of whether they toe link bolts have been changed to a stronger bolt, hard to say without checking the markings on the head of the bolt on the other side.

In terms of whether your toe link system has been upgraded to double shear, as you often see with aftermarket solutions for this issue, no your car has not.

That is the BOE solution and those are NAS 7/16 hardware. It is plenty strong and is on my TT2 race car with 275mm A7s and the biggest wing you can fit. The rod ends themselves can develop play, but if you are asking this its not a big deal to you.

Sure looks like the BOE solution to me as well. Note that if so those bolts/nuts are no longer a metric size, good to know when you torque them again.

Thanks guys! I appreciate the expertise!

Also note that whether you have upgrades or not, keeping them torqued is the absolute highest priority. I am convinced the stock ones are fine when kept torqued, and even the aftermarket ones can walk out (mine did). The best design in the world is useless if the bolts are loose!

@cyow5 - do you have an opinion on boots or seals for the spherical rod ends on a street car? Mine are still tight but have definitely gotten dirty back there, which can't be good for them.

well you didn't ask me, but if you continue to buy them from lotus, they now come with a boot (whereas the 05-07's didn't originally come booted)

Ha! as often as I poke my nose into conversations, you're not going to get a complaint from me if you do. Besides, your input is generally thoughtful and helpful and I didn't know that the new inboard joints came with boots on them.

I've got a fine, vintage S111 RTV brace on there, so all I need is some boots for the inboard Heim joints.

After reading the BOE page on their upgrade option, which it looks like my car has, I'm feeling pretty good about it :smile2:. Of course, I will check torque on them periodically any way. I am a little confused about this post though:

Sorry for the confusion, when I looked at your post, you had only posted one of the pictures at that time.

The official Lotus track pack solution and some other aftermarket solutions also include an extra bar that connects the two toe link bolts in order to put the toe link bolts into "double shear", like this:

Anyway, not at all saying this is the only way to do things. Nor could I explain to you the pros and cons of the different approaches. :) If you are happy with the BOE solution, then that's good, one less thing to worry about.

Here is an explanation on the differences between single and double sheer, Check this :grin2:

Cool, thanks for the explanations, guys!
