98 v70r Nivomat Fooler bolt specs

Bren · Post by **Bren** » 29 Mar 2016, 16:21

Hey guys,

I'm hoping to find specs for drop bolts for my nivomats. Not looking to go crazy low, just a bit lower in the back to get rid of a bit of rake.

Looking to be able to walk into the hardware store knowing exactly what I need without removing the current ones first

The lower 'bolts' on the rear Nivomats are not actually bolts but are threaded headless bolts welded to the locating plate. The locating plate is also an anchor point for the parking brake cable so the plate needs to stay in place. I'll check what the threads are (They are M10) not sure on the pitch though, probably a 1.25 thread and 8.8 grade.

Pictures attached:

: P80 rear nivomat lower mounting bracket

: Nivomat lower mounting bracket stud

: Nivomat lower mounting AWD P80

Distance from the bottom of the bracket to end of the stud it approx. 35mm.

Hope this helps.

Neil.

Thanks Neil.

So if they're not actually bolts and they're welded onto the bracket, how do they come out?

How is this mod done with new bolts?

They don't look to be welded in place only press fit in and held in by the taper and splines on the sides. I'm sure the studs could be removed relatively easily. I'd guess you'd then put longer bolts in place with perhaps several nuts or make up a spacer sleeve on the underside of the lower control arm it lower the Nivomat lower mounting. Remember by doing so you will adjust the geometry of the rear suspension.

Good luck,

Neil.

So if i'm replacing the bolts altogether for this mod, I shouldn't need to know thread pitch and all that stuff when I go to get new bolts right?

here it says "Match the thread pitch of the bolt to the original nuts that fastened the shocks to the lower control arm."

but why would I need to even use the original nuts?

You don't need to necessarily know all the details of the bolt, just don't recommend stainless bolts as they are more likely to break in suspension, so I would look to use a similar grade of bolt to OE. As long as the bolt/nut are matched, thread is of less importance.
