260z 2+2 stiffening up :D

[Gee260]

I'm maybe half way through seam welding my 78 2+2 which will get an rb25/26 treatment and looking to see where to go from here.

 

I  have been researching for months and everyone seems to go Towards the roll cage route which im hoping to stay away from as This will be a street sometimes track car and i think they are ugly. Looking to improve stiffness and hadnleing asmuch as possible.

 

I'm strengthening the angled supports on the tear struts and adding a nice thick rear strut brace. And will be building a triangles front strut support that goes back to the fire wall where I will weld in a brace under the windscreen the whole way across the car to support the strut braces. Was also thinking of the angle supports under the front guards. My chassis rails are in really good condition so wasn't goin to touch them unless it's advices that they need beefing up.

 

So my question is is there anything more I need or don't need to make it as good as possible whilst the car is stripped down with out resorting to a cage?

 

And also my drivers side chassis rail is around 300mm longer than the passenger side is this normal? Ha

Forgot to mention it will be getting a lot of azc parts. Camber tops, coilovers, mustache bar, diff mout,lower control arms etc

I extended my chassis rails to the rear. Many here have done it.

Did you buy replacements or fab some up?

I fabricated some because the 75 onwards floorpans are complex. I cut off the bottom plate of the rail at the corners and made a  full length insert that went around the corner and joined the rear section. Looking back i t would have been easier to replace the wholefloorpan with the flat rare spares type. I'll see if i can find a picture.

Remove both front guards.

Using some 1.8 to 2.0 mm sheet cut into a largish rough triangular shape, stitch weld it over the raised box sections in front of the leading edge of the doors.

This stiffens them up rather well.

Would be awesome if you had some photos I will look in to that as the next step after seam welding

Do you mean from the top of engine bay box section and triangle it down to the bottom corner of the door sill? S it would basically run angled down from the top of the wheel down to the bottom door hinge (not exactly but as a reference as to where you are talking)?
