390 Final Edition Harness Bar mount holes have no threads


Go to solution Solved by TonyKL,

Recommended Posts

Long time reader first time poster.....

Im from Australia, so the car is setup to drive on the 'right' side of the road 🙂

Today I embarked on installing my 6-point schroth harnesses, harness bar, Tillett seats and rails, and at the same time removed the OEM seat belts.

All went swimmingly well (SRS Warning delete etc....) until I went to bolt in my harness bar and to my surprise, the normal harness bar bolt holes were not tapped!

I have searched high and low but cannot find anyone else reporting this issue. Tapping the holes is next to impossible without removing the rear shell (something I am loathed to do in a 1600km car).

Has any only else come across this with the final editions and if so, did you have an off the shelf product (SL updated harness bar etc.) that worked in a final edition?

Being based in Australia, I had procured the simply sport cars harness bar and it is a work of art, however sans the ability to bolt it to the car, its fairly useless!

Also, FYI - if you grab the GPS-09 from AIM Motorsports; you can continue to run the MXLotus build of the TFT dash and make use of the track features - I validated this today when I got the shits with my harness bar. The data is pretty good, obviously not as good as the 2EE version but enough for a time attack warrior to pull some decent data overlaid with track position and timing.

Please Help, I am hoping to find a solution by tomorrow so I can finish the car off this weekend.

I can’t help you directly but I had a harness bar fitted by Bell & Colvill in my FE Elise 250 Cup and I believe it was straight forward. They had to trim the rear panel as that covers the mounting points but all together a simple install. 
 

Also, regarding the GPS-09 module. If you get version A then it works with FE dash. If you get version B onwards it doesn’t. This is due to having to use different parts to make them and therefore a firmware update is required to use v.B onwards (we won’t get this update for FE dashes).

Thanks for the information, I have just ordered one of the SL updated designs that makes use of the seat belt mounts and I dont believe any trimming is required (but will get the Dremel out if I have to). Really hard to find valid info for the final editions. The Simply Sports Car mount is a work of art and bullet proof, I just wish I could have used it.

Regarding GPS and the dash; I really don't like the way Lotus went about this with a nobbled 'MXLotus' version. I understand the need for AiM to protect their market (having invested in the product development etc) but a 'paid upgrade path' via firmware would have made a lot more sense and allowed us to make use of the AiM firmware updates. I got lucky with the GPS and it's working and was able to update tracks etc.... over wifi.

I do find it difficult to believe AiM developed a whole new board just for the MXLotus product. I would love to have a crack at updating the firmware myself but also don't want to brick my original part. I will likely bite the bullet and get the AiM dash but it just seems like such a waste.

Will push on with the install of the seats and other harness components today, hoping the bar arrives before next Friday.

Hi - This is the same with my 240 Final Edition--- There's no threaded bolt holes for the harness bar on the back of the roll bar... Just a sleeve going the whole way through, with the threaded end on the front (where it can't be accessed)...

I went with a V-force harness bar instead, which attaches to the seatbelt holes - this fits perfectly with no cutting the rear bulkhead either....

Thanks fellow BNE Lotus owner. I pushed on taking advantage of the wet weekend and got everything done, now I just need that harness bar! These seats are amazing.

One technical question, how did you mount the small floor bars ?
You drilled through the floor for the vertical screws ? So there are nuts under the chassis, right ?
What about the horizontal screws ? Are there nuts ? How do you technically mount / access them ?

Thank you very much 👍

I ended up using M8 rivnuts for the horizontal bolts

Really nice idea 🙂
Many thanks for all the details 👍

How / where did you mount the lateral belts ?
They are supposed to be mounted directly on the floor for best security, but perhaps you used seat runners here ?

The 6 points harnesses are to be used with fixed seat runners, as per parts finder :
https://www.bellandcolvill.co.uk/deroure?qs=1&preview=1&make=1&model=42&groupid=11564

Wondering then whether or not they could be used with standard seats, well, what would prevent from using them with for example Cup 430 seats...
Any idea ?

Thank you again !

I used the mounts on the Tillet EBR brackets I got with the seats. The bolt size mimics the standard seats and has a sleeve with a spring to reduce rattles/limit play. I dont have any photos of that part but will take some and upload.

I removed the standard belt bucket (and belts) but they would fit on the bracket too.

The rails and EBR brackets are extremely well made and offer almost infinite adjustment.

SL updated harness bar turned up yesterday. Its very close to fitting but doesn't actually line up! Im looking at what I can do bend the mounting plates slightly so I can thread the bolts on both sides, cannot believe it!

Make sure the "V" part of the bar is as far back into the rear parcel shelf as it is possible to go - otherwise there is a bit of a mis-alignment.  Apart from that, mine fitted within a millimetre...

Thanks, mines out by about a mil and try as I might (with the v all the way back) I just cant get it there, gonna sort it with a clear head tomorrow.

Does the SL one fit in the end, was just about to order one.

Seems odd Lotus changed part of the interior just for the FE editions.

We have 100% fitted a normal harness bar to a 250 Cup FE.  But maybe Lotus did something different in the non-Cup cars - it certainly wouldn't be the first time, trust me!

SL bar fitted with some very minor dremel work to get the angle spot on without the standard belts.

Apparently every 50 to 60 cars has them missing. Must be an end of day or work experience kid type of issue.
