I really hate to see this thread die off..We are off to such a great start..we have been working with USLC to get my young son all fitted with his devices and undies.. For all that may be interested HANS is changing the sport model. They have cut pricing. Got my sons HANS for $495!!  He  takes a 13" seat, will get the one with the HANS recess and the halo. He is going to need about 2" of padding un der his butt.
Has any body  got any helpful advice on elevating his feet and bringing the steering column back? He is going to have to have the pedals mounted in front of the steering rack. It looks like no problem save for the throttle  linkage tab.
In  karts I used a Footbox. It was made for small tikes in Tag karts. But it fit right into his oval kart. It really  helped him with leg fatigue..
Thanks
Darin

2 things, you can move the seat mount bar if you need too.  I cut mine and moved it back to get my son off the steering wheel.  As for tire cutter, I use a guy in Charolette.  He will pick them up from INEX cut them and take them back to INEX so they can ship them.  if you want his number message me and I will get it to you.  Don't like putting #'s on forum boards

That is because HANS sold out to Simpson.

They bought up Safety Solutions years ago and so now they have cornered the market on H&N restraint system.

Good, bad or indifferent...I guess we will have to see.

When my son started racing we made hollow like blocks out of diamond plate to prop feet on and reach pedale mine were in middle of bar on frame so had to cut notch to fit  they were shaped like upside down u but flat on top left tabs out each side and pop riveted to floor pan.

Great idea.  600 racing tells me that they now have a foot riser kit as well as a steering column extension. VMS have you seen these ort had any experience with them...the diamond plate is a great idea. . DCpainting, did you use the long  pedals or build the box to the short ones?

thanks
Darin

we tried long throw pedals and then ended up making our own you can get the medal from any metal shop or tractor supply and weld together and then get them where your driver wants them

I use our local steel recycling center to but most of my steel and aluminum. Only pay the going rate for what they pay per pound.

This whole pedal manufacturing/mounting  problem has me a bit anxious...If someone could take a peak at  http://shop.nkrpedals.com/main.sc.
If I mount it elevated from the floor and put a set of pedals on it, He will be using what he is used too.  It is not difficult to change the mounting point of the brake  master cylinder and this comes with the throttle assembly. Tell me what you think?

if you plan on running for or with inex for points you need to be guided by the rule book.

23. PEDALS: Competitors may change the location and length of gas & brake pedals within the cockpit as long as they remain mounted from the top bar as delivered from U.S. Legend Cars International. Pedals may not be cut down or lightened in any way. Adding to the original pedals is permitted. Removing material from the original pedals is not permitted.

Darin, if you haven't already, I would go on website and print off rule book. There is quite a bit to take in.. Both my son and I are getting very excited to race this car! I really hope it takes off around here!
