JohnnyRed Posted January 5, 2006 Author Share Posted January 5, 2006 I added one to my cart for MSA and it was about 85 to ship the whole cart. not too bad. Is there any difference between MSA and autopower. They seem similar. Quote Link to comment Share on other sites More sharing options...
johnc Posted January 5, 2006 Share Posted January 5, 2006 The Autopower race bar for a 240Z is part # 60170L and does not look like the pictures posted earlier in this thread. I sell it for $339.00 which might be a bit more then what MSA charges because they can buy in lots of 10 and get a bigger discount then I. The harness bar is an extra cost option and I charge $61.57. Shipping on these roll bars is fairly cheap because they can go via UPS. I sent one back to Florida for $75. It takes about 3 weeks for Autopower to make and ship if they don't have any in stock.

Jeff Posted January 5, 2006 Share Posted January 5, 2006 I'm a little late but here is the autopower bar installed in my 260Z. I welded it instead of bolting it and have since added a harness bar. I know it doesn't show seat clearance but hoped it would help. Quote Link to comment Share on other sites More sharing options...

Jeff Posted January 5, 2006 Share Posted January 5, 2006 Yikes, I hope you never need it. Well I hope I never need it either but for a street car that may see occasional open track & autocross duty then I'm going with the better than nothing approach. I'm assuming your comment was about the design of the bar and not about the installation. I value your opinion very much and if you see an installation problem please let me know so that I can correct it before I get much further into this project.

johnc Posted January 5, 2006 Share Posted January 5, 2006 One tip to help the Autopower bar out if you're welding it in: weld two .095" thick by 2" wide tabs to the top that also are welded to the roof support at the hatch hinge mount.

katman Posted January 6, 2006 Share Posted January 6, 2006 Installation ok. I just didn't remember the Autopower bar having such a short couple between the main hoop and the rear supports, and both essentially sitting on a sheetmetal ledge.

Mikelly Posted January 6, 2006 Share Posted January 6, 2006 Yup, Jeff's is the bolt in BAR I'm familiar with. The cage they sell for ITS is a different animal all together from what I remember seeing on the units installed in the couple of ITS prepped Zcars I've seen them in.

heavy85 Posted January 7, 2006 Share Posted January 7, 2006 The harness bar is an extra cost option and I charge $61.57. Is the Autopower harness bar just straight across or does it curve back to provide seat clearance? I'm also wondering if it would be best to skip the harness bar and just weld a tube between the towers? Thanks Cameron Quote Link to comment Share on other sites More sharing options...
johnc Posted January 7, 2006 Share Posted January 7, 2006 Its straight. Quote Link to comment Share on other sites More sharing options...
JohnnyRed Posted January 7, 2006 Author Share Posted January 7, 2006 I think it will fit just fine so I ordered a bar. I can post pictures when it comes/get it installed. Thanks for the help. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted January 7, 2006 Share Posted January 7, 2006 Is the Autopower harness bar just straight across or does it curve back to provide seat clearance? I'm also wondering if it would be best to skip the harness bar and just weld a tube between the towers? I had the SCCA legal bar and had the harness bar on it. I welded another harness bar onto it because the original was too low, so the angle of the seatbelt was pretty steep to get over the top of the Recaro seats I was using. Plus it had to go over the seat stop bracket thingy which was FLIMSY. I put my new harness bar between the rear support braces and it reduced the angle of the seatbelts considerably. I later sold it to Auxilary. He might be nice enough to shoot a pic or two if you say please... I can't remember what the acceptable seat belt angle is, but I can tell you that if the mount is too low and the seatbelt goes up sharply over the back of the seat and then down sharply across your chest like this ^ then when you get in an accident when your body moves forward it will also force your torso down, compressing your spine and potentially causing much greater damage. The Honda ricers with their "race harnesses" latched into the rear passenger seats or worse yet the floorboard behind the seats are asking for a paralyzing spinal injury.

Jeff Posted January 7, 2006 Share Posted January 7, 2006 I put my new harness bar between the rear support braces and it reduced the angle of the seatbelts considerably. That is what I ended up doing as well. I didn't like the fact that the harness bar was constructed of flat stock and this should place the belts in a better position.

turbo_fb Posted January 8, 2006 Share Posted January 8, 2006 Theese roll bars dont make tha car any stiffer right? U guys still weld shoring in your chassis joints? I need to make my car stiffer in the chassis but not sure which way to go. Quote Link to comment Share on other sites More sharing options...

I need to make my car stiffer in the chassis but not sure which way to go. I'm stitch welding my chassis right now and I'm making a different roll bar that attaches to the rockers and the strut towers. I'd go with a cage and subframe connectors if its a track car. Stitch welding is a lot of work. LOT of work... Quote Link to comment Share on other sites More sharing options...
JohnnyRed Posted January 23, 2006 Author Share Posted January 23, 2006 Well it came the other day but it was raining out and I didn't get a day off till today. It took about an hour or 2 to install. It fits great. I'm sure I'll feel a lot safer too. Quote Link to comment Share on other sites More sharing options...
Con Brio Posted February 8, 2006 Share Posted February 8, 2006 Hey guys, I'm looking for a roll bar for my "76 and came across this tread while searching. I went to the web site and had a look at the bar. What's the difference between the 1.75" DOM(?) and the 2.0" ERW(?) bar construction? (Besides 1/4"). Is there a benefit to the larger bar in the Z. What have you guys been installing? Thanks. Quote Link to comment Share on other sites More sharing options...

Phantom Posted February 8, 2006 Share Posted February 8, 2006 Another thing I've heard of people doing is welding clips to the roof and actually attachng the roll bar to the roof. Quote Link to comment Share on other sites More sharing options...
dj paul Posted February 9, 2006 Share Posted February 9, 2006 ya thats what johnc was saying, anyone happen to have any pics of this though? or think about what i said about the welding it in and then attaching it with bars to strut towers and then connecting strut towers to eachother?
