Hello,

I want to install a chassis stiffener on my 86 Spider but I am not ready to invest $500+ for it and prefer fabricating my own on.
To make it easier and speed things us - is there any plan of such a stiffener availalable or would anybody share his plan with me.

All helpful feedback highly appreciated.

I look forward to your responses.

If you have the welding skills

Seems pretty easy to me, from looking at the photos of the stiffener from IAP.

You need some flat stock to mount up at the steering mounts inside the front wheel wells. Some square tubing that runs back to the rear swing arm mounts. And some flat stock to produce the pieces that mount to the swing arm mounts and connect the box tubing to the front plates. And the cross braces also.

If you plan on fabricating something like this, I would imagine you have some idea of design and geometry, as well as welding skills. Otherwise, if you plan on having a shop do it for you, plan on bringing the car in for sometime with their team to get measurements and fitment.

What I don't know about is the grade of steel used, the strength of the pieces and what would be needed to do a good job as a stiffener.

Thanks, I am sure that I can figure it out. It can't be rocket science, tie the forward section to the rearward section to eliminate twist.

I too have given and given and .... for years, these days I have gotten somewhat cranky on occasion

Ben - owner of Ralli-Round (former Seattle/Eastlake, now Kirkland, WA) came up with a design that he said was lighter and stronger than the IAP version. Contact him to see what he might be willing to share at what cost.
