Thanks. It's been a bit of a slog and progress has been hampered by the start of college football season and hunting season. I'm anxious to get the cage finished so I can move on to the drivetrain.

A bit more progress today. Got the dash bar level and tacked back into place.

Working on getting the harness bar in place behind the driver's seat. Needs to be higher.

Headroom is going to be tight, but I think I'm good. You need 2" from the top of the tallest driver's helmet to the top of the roll cage.

Your dash bar must be heavier than mine. I only needed a 1-ton jack to hold mine. :D

BTW, have you ever sat in a Kirkey seat like than for two hours? I have, and it's one uncomfortable beast IMO, but comfort is subjective of course.

You know what pisses me off is they used to make a brush on paint called "hammered" and made in Australia if I remember. Its not the Rust-Oleum hammered paint spray at Walmart. It's different and you brushed it on. I used it on all my cages and was really really good.
They do have Rust Oleum brush on but I've not tried it.

I haven't, but thankfully, the car should drink 12 gph, and the tank is only 16 gallons, so no one should be sitting in the seat for much more than an hour.

I'm using Roll Cage paint from a spray can, but I may need to supplement with some brush on.

That's a good thing. We had a Kirkey in the RX-7 originally, and I don't miss it. Have a Sparco now. Much better. The RX-7 will go close to 2 hours if you're at 75-80%. The modified stock tank holds 19 G.

It's called "Hammerite" and made in the UK.

You brush it on, and it flows out and reacts for the hammered finish. [no primer needed]
Word of caution!!

you must fully coat every area you intend in one coat. You cannot go back and touch up a piece you missed.
If you miss a piece, you must wait at least 2 weeks for it to fully cure before applying another coat [or the paint will "fry"]

I've restored a Stahlwille toolbox with the **** [it flows out really nice]

I've never heard of "roll cage paint"
On my Mustang I had to remove a couple of Redneck Add-On bars to bring my car back to FIA homologation specs.
I simply touched up the cage with a spray can white VHT Engine enamel.

Engine enamel seems to be less sensitive to oils and doesn't "fish eye"

I plan to do that today. After looking at my helmets, I think a couple of inches is accurate.

Test fit yourself with the helmet on, and also check pedal and steering wheel distance [holes in the floor can be plugged]
You do not want your arms out straight [you have faster reactions with you elbows down]


When I first drove my racecar I nearly threw up in my brain bucket.
This was caused by my helmet rubbing against the cage [over the door]

The last driver must have been a jockey and didn't have an issue.
I used 2 same side seat brackets [L profile] and shifted the seat over 4" towards the tunnel . There was a huge gap there]

BTW, have you ever sat in a Kirkey seat like than for two hours? I have, and it's one uncomfortable beast IMO, but comfort is subjective of course.

I've used Jaz plastic seats [low back for period correct appearance] which aren't to bad.
But I agree with you on Kirkey seats , they are terrible. I've added polystyrene to the padding on Kirkey's to give the spine a fighting chance.
The best I feel is a MOMO [this will be debatable] But there are a lot of replicas out there just as good.

@bulletpruf if you are shopping for a seat, take your helmet with you.
Race helmets are not like motorcycle helmets [they are wider/thicker due to fireproof requirements.
A "winged" seat should only give you about 3/4" each side lateral movement [and a HANS for forward restraint]

Gone are the days where I would wear a cheap open face motorcycle helmet and sunglasses at 170 mph in an open top sports car and not give a f**k about safety.

This is what we did for our Kirkey seat that make a major difference.
We made an insert for each one of our drivers.

I can't speak to Kirkey's specific 2-part foam kit, but we tried a DIY method using a different 2-part kit and it was a disaster.

I'll admit we had no idea WTH we were doing, and didn't follow any of the prep steps shown in that video prior to pouring the mixture. When we decided the experiment was a bust, the REAL issue came to light with the stuff we were using. We decided to light it on a fire and WOW, did it burn, and burn fast!

Again, I have no idea about Kirkey's 2-part foam kit, but if we had gotten ours to work, we would have been sitting on what was essentially an unstruck match.

FWIW, we run a Corbeau seat in our Lemons race car. It's a fiberglass shell FIA-rated seat and it's pretty comfortable. YMMV of course.

Do you need comprehensive insurance on a race car? It looks like you do!

This video clip is from a buddy of mine who was racing a 2010 Mustang in the Champ Car race at AMP this past weekend. Pay attention to the right side of the track just before impact. He missed the first one, but nailed the second one. My buddy wasn't injured, but Bambi didn't make it.

It's a two-person process at least. Put the driver in the seat with a large trash bag tucked behind them and have someone hold the bag open at the top. Mix the foam and use a drill motor and some type of Wisk in the drill making sure the foam is mixed completely for about 10 seconds then dump it in the bag making sure the drive stays still. Size of driver has an impact on the amount of foam needed, how much of the seat space is taken up by the driver. The inserts were then covered in material.
My BIL purchased the foam, I was told it met SFI 45.2 specifications.
