I posted some more pics of the roll cage install. So far I have the halo bar, a-pillar bars, dash bar and rear shock tower braces in.

I love your car. I love this build.

Who's doing the cagework? I assume you are given what i've seen here. Do you need to be certified to have an FIA approved cage?

Looking through your pics on the rocker panel replacement, was that the initial project which then got diverted into the current one of dropping out the floor pan entirely? I know how that works, just not quite on this scale however! :shock:

I have always assumed that it just had to meet a certain criteria... even if your cousin from up in the hills built it for you... I could easily be wrong, though.

You don't have to be certified to build a cage, which is obvious from how many bad cages are out there. The cage just has to meet the rules for the class you want to run in. The HPDE events I want to go to usually don't have specific cage rules, so my cage is in excess of NASA rules.

As for as floopan removal, I had to remove it to clear the driveline. For the ride height I want the entire suspension had to be moved up about seven inches. That mean that pretty much everthing had to go.

Nah, it's still a Merk at heart. What does your Merk have that it doesn't? A few extra pieces of stamped 20 gauge steel spot welded onto it? :?

It's been slow going on the XR, lots of suspension design work.
I have been working on the front clip of the car and the motor mounting worked out.

More pics on my site.
