fastening racing seat belts
 

There's been some discussion about how and where to install some of those racing seat belts, for example schroth belts.
I'd like to make it as simply as possible, for the rear either the isofix points or rear seat belt clips' screws will do.

But the fix points at the front seats make me worry. Apparently, the oem boltsfor the hinge seem to short, not enough thread. I'd like to simply use some longer bolts.

To try, I'dneed the oem bolt sizes and thread.
Before anyone asks, I'm indisposed health-wise and can only prep, not do right now :(

I have the Schroth 4 point belts fitted. I used the ISOfix point in the rear, and the standard bolts at the front were easily long enough - although you need to jigger around with the front seats to get good access to the bolts, and ensure you put the belts back together per the Schroth instructions.


As long as you have the right tools it's very straightforward.

I've heard reports that the bolt wouldnt connact w all threads in the hinge anynore, sonething I'd like to avoid.

Btw can you show us a pic of how you installed them, please?
Wanting to get 4-point belts myself I'm afraid that the offset created by the isofix points will draw the belt too much towards the car's mid
