Was wondering if anyone knew where to purchase a bolt-in roll bar kit for a 08 Mustang HT that would meet the requirements for IHRA racing for cars running 11.50 or faster. Thanks in advance for any info.
You can have a bolt in rollbar for IHRA/NHRA. However, it requires that you use 6" x 6" x 1/4" steel plates on the top and botton of the mounting point. It also requires you use minimum of four 3/8" bolts to secure these 6" plates to the floorpan..
There are three issues with meeting these requirements from a "kit".
1) No kits are designed for IHRA/NHRA. They are all designed for SCCA/circle track competion and when you want to use them for drag racing they will need to be modified. They dont come with 6 x 6 mounting plates attached. This would require welding on that 6"plate to each mounting point. So if you need to break out the tig welder to make these plates and attach them to your rollbar mounting points, then why bother with a bolt in kit? You may as well bend up new chrome moly tubing and weld it right in to begin with.
2) All these kits are made in DOM (mild steel) which is heavier than chrome moly. If you buy the mild steel bolt in SCCA tyope rollbar and add the plates, it will be rather heavy. Chrome moly would be a much better choice.
3) Rollbar design. You are stuck with their design. So you can not decide the shape of the main hoop, where the rear braces will mount, the angle of the rear braces, the height of the sidebars, the mounting point for the sidebars and orther design decisions. Not all rollbars are created equal and you want one that is both integrally solid, meets racing regulations you want to participate in and one that looks good.
All that aside Autopower makes the kits that are mild steel. They are NOT IHRA legal though.
The Spohn kit is just a repackaged S&W Race Cars pre bent kit, it is a weld in kit. The Auto Power bolt in kit can be made NHRA, IHRA legal by welding the rear bars but then it really is not removable any more. You can't really make a roll bar NHRA, IHRA legal and still be able to easily remove it at will.
Hi; In the 2009 Feb. issue of 5.0 MUSTANG magazine the is an article about a rollbar that is now available from Maximum Motorsports, it is a 6 point bar that is NHRA approved.

It will not be legal as a bolt in unless it has the 6" plates that are welded to the feet of the rollbar and the Autopower doesnt have those.
I havnet seen the maximum Motorsports rollbar but the HNRA rules are very clear about the 6" x 6" x 1/4" plates required when using bolts to attach the rollbar.
I think the poster was looking for a bolt-in in rollbar rather than a custom 10-point cage.
Agent 47 also has a bolt-in rollbar I saw ina magazine but it isnt NHRA legal if I recall.
Try calling Agent 47 and ask about their kit. It was pretty expensive I think.
