Have you checked your top rollbar above the drivers head.
I built my C4 Roadrace car with a similar top bar and my helmet was
in contact with the bar. My seat was sitting almost flush with the floor
and I am only 5" 10'
I had to remove the bar and move it out about 2 inches to clear
my helmet.

Inspectors "like"  to see lower tubes connecting the four corner "posts" forming an upper and lower "halo"

Freud - I agree, much better to see!  Thank you!

Gray63 - Thank goodness I am only 5'8", because he had the upper bar totally straight at first and with the Halo seat 1.5" off the floor my helmet was almost touching that upper bar, so he took it back out and added that slight kick up.
     My biggest worry now is getting my fat butt into the car once the other bars are in place...LOL!

Sparky - Please, educate me more, I really appreciate any and all advice!  I am new to roll-cage construction and want to be sure I bring up your advice/recommendation to him, so I meet all the desired tech requirements and also so I am 'safe'.

Thank you,
Jesse

Redhotracing and lsrjunkie - Thanks for the info. I am hoping I will get the 2014 rulebook any day.

Leadfoot - I have 2.125" dia. Hooker Super Comps that I modified sightly to fit the chassis. Thanks.

When we built our Production VW Passat over the last 3 years, we were fortunate to hire the racecar fabrication services of (, to name two...) Brian Thomas and Tim McNees, both local here in Salt Lake City. Our car has passed Tech Inspection smoothly from its first Speedweek in 2012, and has given us confidence to safely exceed 200 mph at Bonneville dozens of times since... There are tons of build photos on our facebook page. https://www.facebook.com/PotterBrosRacing/photos_stream?tab=photos_albums

Hope that is useful!

Hi Jesse

Are you going to lift off the body to get to all the welds on your cage?

When checking your fit in the car be sure to have all your gear on as you will get bigger

Andy Welker used metal brackets and hose clamps to hold his cage in place , to be sure it all was right then welded it up

Very crafty idea, you might want to check out his tank build as he did one hell of a great build job

What kind of speed are you looking at in your class ?

Looking good, G Don

Just to piggy back on the last post a little, also have your required sfi roll cage padding in place when you do a fit check... the pad in commonly 3/4 inch thick... You do not want your helmet touching anything during a run.

Piggy back #2

Allow for some belt stretch too, not sure how much?

Since you are 5'8" maybe you can recline your seat for more room on top, that would be a good thing !!!
