Show Us Your Roll Bar

AntiVenom · 08-07-2015, 12:12 PM

I am reading this thread with great interest.

I am not knocking the RPM cage. Looks like better than average for bolt-in. I think there are two things that make me wanna go custom.

1) what synolimit mentions about the rear mounting points. I am not saying they won´t hold (I am not an engineer), but I don´t think they are in the strongest spot.

2) i don´t think it utilizes the interior space as well as it could. This is prob ok for shorter guys, or folks that like to sit really close to the steering wheel, but I think it could be moved out.

Then again, I could be completely out of my mind since I have never built a cage. hahaha.

It´s probably about a year out for me, but I will post back to this thread when it´s done.

definitely interested in a group buy, any updates with RPM?

Hi Everyone,

We are interested in doing a group buy for everyone on here. We have a new vendor that is a sponsor here and we will work through him to make sure you all get what you're looking for. We will do some very special pricing along with some freebies for anyone that gets in on the group buy.

I do want to address some of the concerns that were brought up on this thread. First and foremost I have 25 years experience building professional drag racing cars that run in the five second zone. RPM is a division of our hardcore race car division. I follow NHRA specifications on all designs which are usually more stringent then SCCA/NASA rules. The attachment points need to use a 6x6 plate as per rules, the rear shock towers as strong as they may be won't facilitate the use of a sandwich plate which is a requirement, the wheel well method has been tested numerous times over the years. As for the main hoop attachment it MUST be attached at a point that is lower then the driver's seat otherwise the main hoop will not protect the driver in a roll over. Although the upper shelf is a strong point it doesn't adhere to the sanctioning body rules. Most entry level classes would be ok w/the shelf, the NHRA or SCCA sanctioning bodies would likely take exception to the shelf.

If you have questions feel free to ask or give us a call at 503-486-7011

Also we TIG weld all of our rollbars including mild steel. We build our bars in either a .120 dom mild steel or 4130 chromoly in .083 or .095 wall depending on whether you road course or drag race. We look forward to hearing from you.

Regards,
Rob

Any details on how this mounts? Specifically as they relate to backer plates, modifications to interior, etc.

It secures to the floor (behind the seats) rear chasis and seat belt upper mount.
I did report in my blog with supporting pictures, but it is written in russian

As of interior, I've cutted three plastic details on each side, and there's no way to avoid that. It was so painfull to do so, but result is worth it!
here is link... Rollbar

This is my first Japanese part ever which came without installation instruction and even single sticker ! Crisis ??)
