Hey all. I'm putting a Schroth rally 4 harness in my '08.5 speed 3, and was wondering if anybody already running a harness in a hatch could tell me A, the rear mount points they used (I'm assuming the left-rear passenger seatbelt mounting points?), and the torque for the bolts?

Thanks!

Dan

I know this is probably not the safest or even if it's legal in SCCA or NASA, but I mounted both shoulder belts to the hoop for the rear seat backrest latch. Lay the backrest down and there's the hoop. I used clip on belt attaching hardware. For the lap belts I took out the seat and removed the factory bolts and installed eye bolts to clip the belts to. Kept the factory belts mounted with the eye bolts. The submarine belt looped thru a crossbar under the seat.

I installed mine on the rear seat (behind the driver) child seat anchors (shoulders) and the laps directly where the stock belt are (you may want to get a couple of longet bolts for that...

My lap belts are installed in the stock locations as well. The stock bolts are plenty long.

I was told by a fellow driver to mount them underneath the rear seat cushions, ........ Someone needs a sticky on this one...

got a few pics that may help










bring it dano

this harness setup works well for tall people, but for people who need the seat far forward the straps arent really long enough

The shoulder harness needs to be at an angle between 0deg to 20deg from the horizontal plane, this is to prevent spinal compression in the event of a crash ! I would bolt it onto the OEM rear upper seat belt bolt on C pillar if possible.

Depends on which harness, the rallye 3 will bolt to the c pillar, the rally3 4 bolts to the seat belt locations. My friend that runs a evo has a rallye 4, bolted to the seat belt locations, works just fine for him.

The way the Rallye 4 harness is installed in the post above with the photos is the approved way according to Schroth. They specifically say DO NOT attach to the C-pillar.

I use this for auto-x no problem. For HPDE's I use the OEM seat belt only.

That one bolt, the one in the center of the back seat was a real pain to get out.

I pulled the rear seat out made everything pretty easy until I started to crossthread one of the bolts! I had to repair the threads this morning.

The child seat anchors are only rated for 150 lbs. I'd be worried about snapping them off.

I am installing a Ralleye 4 harness in my 3-- i got 3 of the connections done easily, however i can't figure out how to get the seatbelt buckle off to install the final corner. It's not a normal bolt like the other 3 are.

This is different on my normal 3 than on the Mazdaspeed3, which does have a normal bolt there. Not sure how to describe the head on the bolt holding my seat buckle on, I just know I don't have any tool to get it off. Did you encounter this as well in your normal 3, and what do I need to get that weird bolt off? Or, did you install that front-right connection in a different location than the speed3 guys do... like one of the rail bolts or under the center tunnel somewhere? Thanks.

For my right hand lap belt (on the drivers's seat), I used the bolt that connects the buckle to the seat. It is a normal bolt in my car. To get it out I raised the seat all the way to the top and moved it back as far as possible to access the bolt.

Hmm... you have an 07... then I'm guessing it's only the 04-06 models that used this weird special bolt. It has kind of a hollow star patten inset into a short round head (almost flush). Maybe I'll call Schroth and see if they have any experience with it...

 

[CosmicBlueMS3]

the type of bolt you are talking about is Torx head
can get the tool to remove it at any decent auto store

 

[cali_axela]

Thank you sir! I actually do have some torx bits in my craftsman set, but the biggest isn't one nearly big enough to fit this head... guess I need another set of larger ones?

yes I have that wierd torx bolt as well, and a pain to get to. What I have done at times is just attached that particular part of the harness to the bolt that holds the back part of the rail to the car.

That's exactly what I was thinking of doing, just wasn't sure if it was as secure of a mounting location. Even with the seat all the way up and back, I can't get in there to get the freaking torx out since I have a straight screwdriver-style driver for the torx bits.

Do they make short ratchet-socket attachments for torx? That's the only way I can see getting to it.

Actually I think taking out the middle console is pretty easy(At least I remember it being easy when I installed my short shifter).
That should give you plenty of room to go in there and replace the torx screw with a regular hex head one.

I do think they make hex bit adapters for rachets.

 

[cali_axela]

True, I can take out the center console pretty easily, I did it for the STS install too. I guess that'll be the plan.
