Hi,

all ive noticed my shell has alot of rust around the inner wings.
its around the vents for the radiator and the hole for the duct!

Ive looked around the search button and cant find a clear answer really!

Im gonna fit a flip front next year when my insurance will hopefully drop, so im thinking of removing a large section of both inner wings.
Will i need to fit brace bars?
and would this fail the mot?

thanks martin

Post a pic or two and we can then advise about the MOT issues.

You WILL need brace bars with the flip front.

Ive seen a lot of cars with no inner wings and no brace bars. Make of that what you will. Dont know about MOT status. I would brace it. Paul

but if i cut them out would it make the wings and front panel less sturdy?
just i would fit brace bars i think, but im just thinking on how the front end stays sturdy!
thanks martin

I'm still to be convinced of the benefits of brace bars.

If you think about it from a suspension point of view, they do nothing. Also, as far as engine mountings go, they do nothing. They don't stop the subframe moving side-to-side as they have no strength in this direction.

All that they do is stop the subframe pivoting on the top mounts under acceleration and braking. However, with solid mounts this isn't a problem.

IMO, the front subframe mounts hold the front end up rather than the other way round (as is conventionally thought)

Good points but you try and convince an MOT inspector your right (which you probably are) and you may well be on a road to nowhere.

Brace bars 30 quid from minispares. If anything they keep the MOT man happy and you can mount stuff on them

I've mounted my horn and tie wrapped the front loom to the drivers side one.

In the pasted Ive had the early starter solenoid there to.

This is how much of the inner wing to move (see link)

Just take them back to the bulkhead.

Wil, Ive seen massively distorted floorans from not having brace bars, these have been on high output engines.

That dosent suprise me Paul, this is why I strentgthen the floors. I have brace bars too.

I just think it's something that is blindly done when fitting GRP front ends; I know I fitted them without thinking.

After thinking about it now, I would not fit the normal type brace bar, there are better/neater/lighter solutions.

Wil, agreed, I like what Fastcarl made for John Haston, its an alloy bar with rose joint on each end with brakets welded to the bulkhead for said rosejoints. Ill see if I can dig up a picture.

I would think they do a lot more than you think. Acceleration, breaking, steering loads etc will be spread over all the subframe mountings. If there really was no load on the front of the subframe, the teardrops would last forever.
Even with tower mounts, all you are doing is increasing the loads placed on the bulkead section where the tower bolts up.

For an experiment....unbolt your braces at the inner guard, and mark them somehow, and drive about for a while, to see if they leave any marks as to how far they actually move.

Even when my car had stiff rubber floor mounts, std tear drops, and solid towers, there was some strange noises coming from the bulkhead area under hard acceleration etc. I never did find any signs of where the noise was coming from though.

No way would I remove the front end, without bracing up the subframe. Id probably like more bracing than the 2 simple bars too ( or at least strengthen the inner guard where they bolt up. )

Hi,
I'm with Stevie on this one. When you accelerate the enigine is trying to rotate in the subframe, which in turn is trying to rotate in the shell. With nothing attached to the front of the subframe it will try to pivot around the tower mounts which as mentioned above will distort or crack the floor at the mountings.
Cheers,
Gavin :)

Yes I agree, as you can see this is what I said originally. What I'm getting at is that with well designed solid floor mounts and a sensible strengthening plus good solid top mounts the brace bars do less of a job.

I really wanted to get people thinkling about what they do. I think mods to the subframe and floor mounts could eliminate their use entirely, but brace bars are an easy fit option.

I do have brace bars, but I reckon their 50% of their job is for mounting my front end and making the wiring a bit neater.
