Track Roll bar options

[angusis2fast4u]

Thanks for the responses guys, good information shared. I HAD an mx5+ Torx box in my old mx5, I liked it but it can look like a style bar at times. This time I want something aesthetically more aggressive, that also means safer...in a way. I have decided to get the Hardtop AGI rollbar as it comes back to the very rear of the parcel shelf so you can still access fuel pump and use the parcel shelf as a storage area, only downside is losing the soft-top but that is a excess weight anyways haha.

The car will stay a street car, I'm not building a full track car I am building a street car which will see a decent amount of track time when possible. I want to start participating in Street sprints at lakeside and QR. The AGI bar is cams spec so I don't think i'll have an issue getting into that

I reckon you already know some events require you to have a particular type of padding on the bar and to spin 347 degrees on your left leg?

Whilst the Plus single diagonal bar is not CAMS approved, it can be if required. For street sprints at QR the Plus is more than adequate.

A road car that will see a lot of track time... This will always be a compromise of something, I have been told this many times and it hurts to say but they are right. Pick a set of rules and build to that. The Time Attack series in QLD has a good set of rules to look at WTAC clubman class or CAMS 2F. You could even go most of the CAMS 2B but some of the aero will not be street legal.

Are you going to the MX5 car club track day on Monday? This would be a good place to chat with others about having a road registered track car. Mid week sprints is also great to chat to other drivers.

Good luck with direction, it is not easy.

Thanks for the response, Do you mind I ask what rollbar you have in your blue car? as I know it is still registered (to my knowledge). The plan for this car is to build it for the street ultimately, and then if my car complies with a certain series' rules than that's good because that means I can have fun on the track too. I don't want to my car for a certain series or class as I drive it 99.99% on the street, but obviously I will consider doing certain things or not doing certain things so that I can run it on track.

Where is a good place to look into what series are available in this area and what the car needs to comply with? I haven't read into it much at this point

Maybe I’m missing something but you’re saying 99.99% street, but also ‘building a street car which will see a decent amount of track time when possible’, yet ditching the carpet and soft top to get a more ‘aggressive looking’ roll bar? I’m all for hard parking and telling people you plan on going to the track, but also have to question the logic.

What’s your actual goal here?

If it really is 99% street i would say not to get the AGI.
It is designed to provide maximum protection at the track in shoulder width and height.
Also mounts on the strongest sections of the car but the downside to this is it has a slight interference with the seatbelt and seat travel is reduced.

If it is not mostly track work then i would recommend either the BD or Automotive Plus bar for on the road.

I know exactly what I want to build and and what I don't want to build so i have a certain goal every mod will help me reach. it will see track time eventually once I have roll bar, wheels, coilovers and a bit more power but until then no i'm not going to track it on suspension which was never designed to be used in that way. I have probably not described it in the best light but the best way to describe it would be "aggressive street car", but everyone has different opinions on what a street car is or should be.

The position in which my seat sits would not be affected by the "shorten seat travel" so that so it doesn't affect which bar i'd buy. I don't want to be sacrificing the added safety for seat travel which I don't use anyways, plus the AGI bar just looks better than the BD and MX5+ bars

Hard parking. Got it.

I liked the look of the MX5+ double diagonal bar, which honestly was a factor in getting it myself, but could well have been swayed by the AGI bar if it existed at the time. Either way, I don't think you'll be disappointed. Both appear to be quality pieces of kit.

Personally I wouldn't go for the hard top only bar as having a soft top on a street car is a really useful thing, but if you think you can live with it then by all means.

Hmm, 50% of the motorsport group of the Vic MX5 club track it (regularly) on the suspension as it was orig designed and they seem to do just fine.

Nah not hard parking this time, I did that to my last mx5, I put 15x8+0 wheels on it and had it stupidly low, needless to say once I put on 6uls with 225/45 R888's on I never went back to the other wheels. I plan to do the same this time but do it properly, so instead of buying a torx box roll bar ill get something CAMS spec so I can get into events if i want etc. but then i'd also like it to look good, and that AGI roll bar looks amazing!

Keep in mind that any of the "double diagonal" bars won't be CAMS compliant.

Also keep in mind that, depending on what class / events you intend to enter, you may not need a CAMS compliant cage / roll bar. Cages / roll bars aren't compulsory in supersprints, track days, regularity, motorkhanas so as long as the scrutineer on the day deems your rollbar to not be "dangerous" (ie bolts sticking out, sharp bits, etc) you can run anything (or nothing).

Mine is a single diagonal Automotive Plus. Yes it is still road registered.

Thinking about my build it is better to have a plan than no real direction.

Time Attack series run at QR and Lakeside. Come out to JapNats at QR on 30/05 and speak to some of the people there.

Queensland Raceway web site has all the details on its Sprint series.

CAM website for details on 2B/2F

World Time Attack website for their rules.

Hardparking

Top Definition

The act of owning a Japanese car riddled with roll cages/high-end race suspension/expensive forged wheels, and never taking it to the track. These people frequent places like honda-tech.com appearance/cosmetic forum, and can often be found arguing about rotas and other parts that they don't do sh*t with anyway.

Example: Ayo, look mang, he got the 36 way adjustable coilovers, hes mad hardparking dawg.





Edit: I should probably add in here that I'm all for hard parking, so don't interpret this as a piss take. Contrary to what the image in my signature may look like I do, my car comes out far more regularly for meets and shows than it does for track work any more. Needs moar GT wing though...

[Magpie]

More Wing....

If you don't track the car on stock suspension with stock power how do you figure out how&what you want to upgrade? You need to set a baseline.

Even if you fluke your mods into something workable you miss out on the journey of horse and rider progressing ability together as 1.

FLick having a car that is faster than you are.

Fit a half cage, have your car properly aligned and go directly to the track. Do not pass go, do not collect $200.
