Need bolts specs to install Madness Lower Stess Bar

I just received the lower stress bar from Madness Motorworks with no hardware included. I've read that's its junk anyways but had planned to use it for an autox this weekend until I had time to get something better later.
Well now I'm forced to get something better in the next couple of days and hoping one of you might know the specs for the bolts (i.e thread, length) for the rear and front bolts/studs? I'm not able to pull the bolts to find out what they are (again a timing thing). I also read you can cut the front bolts but I'm really not looking forward to having to do that....

I found in another post that the rears are 10mm bolts, 80mm long with a 1.50 pitch. Can anyone confirm the bolts/studs for the front attachment to the subframe? Any help would be awesome! Thanks in advance

2004 R53 6spd.

Why not just call them in the morning and get the specs from them. Right now MM is not doing so well on NAM.

The rear attachment point is secured by the bolt that goes thru the lower control arm bracket. MINI specifies that this is a one time use stretch bolt. Some people reuse that bolt but it is designated a one time use for a reason. If you replace that bolt with new ones (part# and size can be found on realoem.com) you can cut the old ones for the front attachment points. Each car may be a little different as to the length that the bolt will bottom out so it would be best to check your application and then cut them.

Im not sure i get how you can cut the old "rear" bolts to work for the "front" mounting. I watched the madness install video, and the studs they use for the front appear to be much shorter, like at least an inch or more shorter.. The bolts they pulled out if the rear where noted as the oem bolts and dont look fully threaded.. Am i missing something..?

Thanks for all the advise

I am aware of some self tapping bolts for front suspension components but no "one time use stretch bolts". BMW system has no "in conjunction with" specifications listed for these MINI suspension parts.

Where did you find that info ?

Thanks!

Both the Bently and Hanes manuals have this information.
