Rear brake disc retaining screws

[richbk]

Hi folks . Just doing little ferrying jobs on the exige whilst I wait my new harnesses touching down so I can actually drive the thing . 
despite being relatively new and not rusted in place the rear retaining screws on my discs appear to have developed a cheese like consistency and I have had to remove with larger torx fitting . Does anyone know what size the bolts are and if an off the shelf euro car parts item will suffice as I can’t bring myself to pay the 8.34 postal charge for a £4 item from the usual lotus suppliers ?

or if anyone has 2 spare they could pop in the post in exchange for a beer at LITP or similar meat that would be awesome

cheers

Hi Rich - just measure the thread length and order some stainless ones on eBay.   I think they are M6 or M8, have a look in the PDF parts manual.   No need for high tensile bolts here I don't think, all they do is stop the disc rotating when you are trying to put the wheel bolts in!  I'd put a dab of copaslip on them too.

 

You'll probably get about 10 for under a fiver, delivered.

Should be M6x16, but best to double-check against the ones you have.  Not sure I'd be replacing with stainless steel, though, unless you're absolutely positive that they are more cosmetic than functional.

P.S.  Seems like they don't really do anything, so stainless would be OK, or nothing at all.  Makes sense, the S1 doesn't have them.

Yup , checked my S1 and they are studs not bolts and tbh don’t think they achieve much as the bolts hold everything together when the wheel is on. Don’t think I can delete on the grounds of weight saving , but figured I should put some back in if I have taken them out ! 
thx for the sizes 👍🏻

Might be a touch embarrassing if the disk fell off when you took the wheel bolts out.

Nice website Chris!

I'll keep you in mind when I next need some bits.

Are you developing any other products?

I don't need anything but stupidly went on the website. Everything looks so shiny and good I just dropped 90 notes on the 'precious'
