SW racecars Lemons roll cage package

I would strongly suggest you use one of the the following...almost all of the cages that get cut out and redone or require extensive rework at the track are one of three companies not on this list:

Roll Cage Componenets
Evil Genius (aka John Pagel, the head of safety for this organization)
A professional roll cage builder that will actually read and follow the "How Not to Fail Tech" (its mostly a picture book) and not make comments like "but this way is better" and "we have always done it this way".

Knowing what car you have and where you are will help a ton.  Keep in mind, most pre-bent cages from major retailers are designed for installation with a portion or all of the interior intact...this will rare pass tech without modifications.  One of my teammates installed one such cage for a new team and even after eeking out every bit of extra space he could during the install...they were told to start over (think they were allowed to race that weekend).

FYI, a 7" spread in height is not very significant unless someon has an unusually long or short torso.  Most of the time you can make the 6'2" person a tiny bit uncomfortable and use a seat insert for the 5'7" person allowing you to do a fixed seat.

Where are you located?

FWIW - I've used S&W for a pre-bent roll cage on three builds. They've been great cages, but come with a few caveats:

1. Even if there's a kit already available for your particular car, do your own custom measurements. S&W has a worksheet with all the necessary measurements required. Simply fill out the blanks and send it off to S&W. Make sure you double or triple check your measurements though. If you fuck up a number, that's all on you!

2. You will likely bend your own door bars. The S&W kit comes with straight door bars. If you call and ask them nicely, they will add an extra foot or two to the raw door bars so you can bend your own custom design. Otherwise, you'll be stuck with straight door bars. This might work for larger cars, but is going to suck for access in smaller cars.

We used S&W for the cage we're building right now. They cut and bent everything exactly to our measurements. So like Bayley said make sure you measure everything perfect, if its wrong it's on you! We spent like 7 hours measuring and remeasuring our car to make sure everything was right. We also gave them some dimensions a little long so we could trim it to fit.

They will add a bend in your door bar if you prefer. We went with the X bar that the kit comes with and I just had them put a bend in the middle of it. I don't remember the angle, but I did some rough math and came up with it. I had the door bars made pretty long so account for this.

One kind of odd part is that they don't normally stock 1.75" 0.095" wall DOM so you have to wait some extra time for them to order it. It was only an extra week or so for us. But then again, you could always just use the 1.75" 0.120" wall that they keep in stock.

I would definitely use them again.

Welcome to the madness Jesse.

I can't comment on the roll cage (we made our own)  but as far as the seat.

I used a Kirkey Road race seat in our latest build and everyone on the team loves it.  Just the right mix of support and feel without being harsh.  Good value too.

My drivers range from 6'3"  to 5'0" and  there are some major mass differences.   So we HAVE to put the seat on sliders,  if you end up doing the same thing, don't skimp, get something beefy like Sparco sliders or the like.  We use an adjustable seat back brace from IO port,I like the extra support/safety of having it.  Even with the slider we still use a support pad for our smallest driver, many teams do.

If you do decide to mount the seat solid, take your time when it comes to mounting the car.  Me and one of my other drivers are both 6'2",  but I'm ALL leg.  So even though we were the same height we could not have used the same seat position, his head would have been above the roll cage!

The seat can't recline per the rules.  But you CAN lay the seat back at an angle if that works out better for you and the team.  Again use your head sure the mounting is beefy.
