from what I know you need to custom fab one, or have it done for you. The one for the coupe doesnt clearn the top from what I hear...

I addded a CP Racing front strut tower brace (attaches to the strut towers AND the firewall) and it helped a ton.Do-Luck makes a brace that goes on the floor behind the front seats.... I'm looking into having a brace made for the rear strut towers....

Yes, you can, It will be ugly but it's the only way the convert will be ever allowed on a race track(even for a fun run, sanctioned anyway). The hard points where the seatbelts would normally be on a coupe/hatch is where the bridge is made over the head of the seats and back down in a upside down "u", then, a x brace behind the front seats on a diagonal to the rear seat top sides to the bracing hard points there.Get a welder to do it cheap! Good Luck, -Jarret

I don't think a rear strut tower brace can even fit back there. Plus, there are two cross braces connecting the strut towers.As for the roll bar. A custom one will work best. The one by autopower contacts the top when it's up. The two rear feet go back too far before angling down. I think they were trying to keep rear seat room in the coupe, but the convertible's roof angle is different from the coupe.

You're out of luck with the floor bar by do-luck, it ties to the seatbelt hard points on the normal cars, and since the dors hold the bottom belt mount, It's useless. The best solution is a strut tower bar!-Jarret

if you go to IO port racing, there is a "convertible" option in the drop down "roof type" menu for 240sx roll bars. Has anyone tried one of those? I was under the impression that it was a different roll bar than their coupe/hatch bars and should fit the vert...?
Wangan with my wang out.

http://www.ioportracing.com/Me...AP670Hopefully that link works, if not just go to http://www.ioportracing.com and go to roll bars, then select from the drop down menu. I have been reading all the back posts in the convertible forum and it seems like people tried to fit the coupe bar on the vert, but I didn't see anyone mention selecting "convertible" as their roof top and seeing what happens. I think the best bet is to have one made. By the time you get the autopower race roll bar (the cheapest one I would consider using) with a harness bar and shipped to your door its going to be around $500, which is what it would cost you to have a similar one welded by a shop.

an old member of our boards ordered that bar (this was about 2 years ago). He confirmed that that bar does not work because the rear feet interfere with the top when it is up.

I read his post and he said he tried the "coupe" bar, I believe. But its way too much money for shipping to have them build it and send it and have it not fit, thats for sure.

wow back from the dead!lol for the record I called IO port like last week and they said that the vert bar drop down list option is just a generic list and they dont make a bar specifically for the vert. But if the coupe bar works and just hits the top then I need to know that because I dont have a top. It would be cheaper for me to buy the autopower and have the rear feet or rear bracing modified than to build a custom bar. Can anyone confirm that the main hood and everything from a an autopower coupe bar does physically fit inside the vert? also avoid those cusco "cages" like the plaque they are good for posuer value only. They won't pass tech anywhere and I seriously doubt with their heim joints that they would be much good for stiffening. They use relatively thin wall tubing as well, and at angles that make me question their ability to hold the cars weight in a roll over. The way the front bars bend around the dash, they would probably just collpase there if any real load was ever placed on them. And that would probably put you in more danger of being injured by the rollcage than it would save you from danger of being crushed in a rollover.

This is Dukeboy's vert. He's got a POWERZAMCAM 4-point roll bar (assuming that's custom made) and a front strut bar.

I was going to use my vert for the track or something, but I might just use it for cruising. I plan on buying another 240 later on. (S13 hatch or S14 kouki) I'll use that for track instead.

oh yeah. forgot i had loaded this off of my camera a while back 






Thanks again to George (Dukeboy) for letting me snag those pics. I really like the overall design, except I would add an SCCA style cross bar to it and make it a bit narrower to allow the interior to stay in.

no problem.i just realized that his bar leans too far forward to add in an SCCA style cross bar. The seats would get in the way. So I guess another alteration I would have to make is to lean the bar back at a bit more of an angle

yeah I would want the bar back a little further and the uprights going to the strut towers (with a plate cut to fit the tops of the strut towers for extra strength). I'd defintely want to take advantage of a diagonal brace for rigidity and a harness bar for convenience. Besides, if you add a tube back by the strut towers like he did, and a harness bar, it would make the perfect tire rack for SCCA events.

Great topic!slownslurious; Your absolutly correct. The Cusco stuff is sorta cheesy. I also am curious how an "A" pillar bar with 3 bends, also called an "escape bar" can be safe? However, from my understanding the Safety21 version is made of bigger and thicker tubing and is a much more serious cage made in the same manufacturing facility. I will be adding the final portions of my cage (Clevised main hoop and kickers) in the next couple months. Of coase, I'm no expert but I've been around quite a few race car builds in my time. From what I've seen it is always safer to make boxed in base plates instead of welding a plate to the top of the wheel well or directly to the floor pan itself. I personally have seen two roll cage tubes, base plate and all, ripped completely through the floor pan and compromised the drivers safety severly. If you are planning on adding a cage or just a structural bar, don't chince. Consult someone that knows what they are doing and at the end of the project you will have the peace of mind knowing you are safe when your behind the wheel of your car. Remember, you get what you pay for. Just my .02

its probably a good idea to take in an SCCA or NASA rule book even if you are only planning on using the cage for time trial or drift.

The rear braces are welded to the wheel wells because I cant get them to go back any farther while still allowing the top to move up and down. Otherwise it would hit the side beams when it folds down. Plus I can still fit 5 tires back there and some other junk. I didn't want to cut out the stock rear brace just yet and remove the top to weld to the strut towers. I am going to put in a full front cage for next year and haven't decided whether or not I want to remove the entire pump and lift assembly to make it manual open/close. If I do, I will just cut out the rear braces and weld them to the strut towers. I will probably do it anyway. | Quote, originally posted by tenkawa_akito » | i just realized that his bar leans too far forward to add in an SCCA style cross bar. The seats would get in the way.

The main hoop is so far forward because I am too tall and I need it to be that high. Otherwise it would hit one of the cross beams on the vert top. Shorter guys might be able to move an inch or two back but will have to lower the hoop height to clear the cross beams. But then it might be too far back and might not have the verticle ridgidity as one that is more upright. It's going to be a whole new world next year. we Just have to wait and see what we will do.

so many safety concessions made to save the soft top!I think I may just order an autopower coupe one as long as the main hoop fits inside the vert reinforcements I can modify the rear to fit... I dont have a top so top clearance isn't an issue.
