UrS4; Replacement subframe bolts

[hunker7]

I've ordered solid subframe bushes from AKMotorsport and they come with M12 10.9 spec bolts for the rear. I wanted to get new OEM bolts for the front and they're of course NLA. So can I use 10.9 spec bolts for the front and what would the torque settings be for front and back bolts?

What is the part number for the front bolts you need? I got some for mine from Audi last week, the ones that got through the bottom arm with the thin metal sleeve. I felt violated when he told me the price

Hi Andy, I'm after item 17 PN; N 90583401 TPS said they've been made NLA back in 2015.

These should work

They're slightly longer so you may have to cut them down if they bottom out

I was thinking if getting these. Wouldn't it be ok to just get one that's 5mm shorter?

I'd go with the longer one to be safe, you can always cut it down, you can't stretch one that's too short!

Good point I ordered 2 120mm ones

My S4 has had Thuppu Solid Aluminium mounts on front subframe and anti roll bar,
The bolts are just 10.9 17mm head universal type items and no issues with coming loose and has had a ton of abuse in the 18 months ish of useage

Just use Loctite and torque to original specs

Cheers How does she feel with solid bushes? Any extra vibrations/noises?

Need to find out torque specs for subframe

feels fine.

has new everything up front, Bilstein inserts only rubber bushing is ARB to track control arm an even that is very stiff!

You do get "noise" from solid mounts etc but the steering and overall suspension feedback is worth the harshness, as the manufacturers describe it as.

oh and top mounts are "rubber" but generally the so called noise would not bother you if you know it is solid mounted
