If I do this, am I really any safer?

[Dudeland]

Ok, So I just finished putting on the rear fender flairs.  I sorted out where the power connectors are going to live.  After the floor is done, I will put in the bases for the new seats.   

 

Has anyone built seat mounts that tie in with one another?  I thought I could try to do something where it would provide better side impact protection.  

 

Regards.

Every FIA car has to have them

Oh, very cool. Ok, I will run with this. 

 

They are under the seats, yes?

 

 

Thanks

Yes, seat rails connects to these.

There are kits available if one does not want to tinker all of it by themselves.

Yeah, it's actually a pretty good idea,

as it ties the seats to the tunnel and rocker sheet metal far

better than the stock mounts do,

and it does offer a bit of crush protection.

 

I think the extra seat support's the real winner, tho.

Ok, good to know.  Got some metal stock the other day to do it.  I will take some pics with measurements.  LMK what you think.  Now is the time to beef it up.

Here is the dimension of the bits.  Essentially I will have a bar running under both the front and the back.  Grade 8.8 hardware holding the seats in (bolts welded through the bars, top and bottom).   Where the bar meets the body I will weld in a 5x3 4.7mm plate on either end to tie it into the rocker and trans tunnel. 

 

I will likely tie both the front and back bars together to form an "H" pattern. 

 

How do I transmit that energy around the trans tunnel? 

 

Anything else I am missing? 

 

BTW got the fender flairs installed (finally).  Lots of room for those tires. 

 

Holly cow this thing needs a wash. 

 

Thanks

Remember there’s still got to be room for a trans and driveshaft going through that center tunnel that you’re gonna be piercing…  😄

I like to use these for such stuff  - they exist in various sizes

Mine are welded, but the bolt plates are good, too.

I'm all for doing a better job securing the seats than BMW did on our cars and your approach will do that and provide some protection from being t boned on the track where most cars are running at the same height, but on the street most bumpers will clear the rocker tops and hit the door, your 75 should have the reinforced doors which might help a bit.

Cool. I’ll need to do custom mounts for my seats and will copy this idea.  Hopefully I’ll be at this point in a few weeks but that’s very ambitious.  
 

Please post pics when you have them in.  I guess the only downside for a street car is reduced room for rear seat passengers to tuck their toes under the back of the front seat.  
 

flares look nice, btw.
