Msp Rear Strut Bracing

WE ARE JUST LOOKING FOR INPUT WE JUST FABED UP THIS REAR STRUT BRACING.WOW Talk about stifness this is our template brace. we are just looking to see if people would be intrested in this piece it will be very much a bolt in product and will be powdercoated or anodized in every EVO color. The Spare Tire is in no jeapordy and factory interior will need liltle modification please give us your input on this product.

That would be so dangerous if you were rear ended!

If it's a simple bolt on, meaning no modifications like drilling holes to mount the bar and the quality is there I'd be interested. Of course it also depends on how much....

How about some specs. Like what material, hollow or solid, mig or tig, number of pieces, and how much it will weigh?

it is 4 pices the one in the pic is mig welded but the finished producct will be tig the its 2 and 1/4 inch steel weighs aprox 7lbs and will sell powdercoated for about $299 no holes and yes somke holes will be needed but a template will be included

As for the rear end Collision it will add quite a bit of support in absorbing shock granted it willpush in to the floor and need to be pulled but same as if it wasnt there ina reare end collision

You couldn't be more wrong! You need to dissipate energy by allowing deformation in an impact. Your structure would transfer all the energy to the shock towers which are non deformable structures on impact. If you had designed in break points or deformation marks I'd believe it, but you didn't. You need FPA software to do such things. Not to mention compare your software modeling to real world performance data to then fine tune your mesh and your physics model until they coincide with each other.

I feel a pissing contest coming on.....
The purpose of a roll cage is to keep a race car driver safe in the event of a high speed colision where there is a great possibilty of the car rolling.
Now in a colision whe you rear-end someone or you get rear-ended the car is designed to take the impact by having "crumple zones"

What you also need to remember is that when we are in our cars we are mostly wearing a 3 point belt if any belt at all. In a race car the driver can move his arms and head a little.

Dude, this is a rear brace that is designed to stiffen the rear unibody. It will show benifits to roadracers and autocrossers. It is not supposed to be a safety conscious product designed against rear end crashes. If you get hit hard enough to deform the strut towers then you will need a new car anyway. The design looks very purposeful to me, yet there will always be those that like to shoot down products unless they have a HKS-CUSCO-or Ralliart sticker on it.

A roll cage is there to prevent the deformation of the roof and to transfer the energy from a roll over to the floor pan. They are not as effective as a deformable structure and as such F1 cars now have driver protection roll hoops and a structure around them that is designed to shatter on impact to dissipate the energy. The main point of a roll cage is to prevent the roof from collapsing and killing the driver. In a traditional roll cage that comes second to preventing the transfer of energy. When you have a 4 or 5 point belt there is less of a chance of internal injury during high g loading and deceleration. In a street car with a 3 point belt it's crucial to have a controlled deceleration and to manage the g forces exerted on the passengers.

All I'm saying is there's no way I would install this and run it on the street. If it had a quick release maybe then I would consider it. I would also say that you should hire a structural engineer to design it for you. Your current design is complete over kill and you will be able to achieve the same results in a crash friendly design. PM me if you want to hire my engineering firm to do this for you.

What I am saying is that even a minor collision will deform the strut towers. This will send the majority of the collision forces to points in the structure that were not designed to absorb those levels of energy. The rear box of a 3 box car design dissipates a huge amount of energy. Where the strut towers are located the energy dissipation ceases to be effective in order to protect the occupants. I'm an avid roadracer and former autocross participant, and I would never install this unless it came out easily after the track. You're asking for a huge liability law suit.

You are missing IzenGrayEVO7's point. The issue isn't whether the car will get more or less damage with this thing installed, it's that you're likely going to DIE if you get rear ended with this thing. With no rear crumple zone, your head/neck could easily be snapped. Or the dang thing could poke right into the rear seat compartment and impale and rear seat passenger.

The point is, this is nothing like adding a rear strut tower brace to your car (as the subject implies).

Personally, I wouldn't even use it on a track, as you're just as (or MORE) likely to get in a wreck there as on the road.

Rob W.

P.S. A roll cage creates a protective, non-deformable shell around the driver. But then there is a crushzone all around that cage which absorbs impacts. As has already been said, this brace is transferring all the impact into the passenger compartment.. not good.
