Hey gang - we have just released a 32mm A-Spec Racing rear sway bar. This bar was developed for one of our Grand Am Cup efforts. It's a hallow bar design and includes a subframe reinforcement/mounting plate.

Please note that the pictures below are from our Mock Up... the final production pieces will have a finished look and will be annodized.

that is sick. I like the fact that it is a true torsion bar. I wonder what it costs..

 

Holy jeezus...

Any pics of it installed?

 

holy mother of hades.....

there is just no point....

i woudl advise noone that drives thier car on the street to use this. If you barely tapped the brakes in a curve you woudl die... For some reason i dont think many DC5 drivers are good enough to use such a bar.

but if your car is for the track only!! Hells yeah....

the design also seems to call for drilling?

Remember, it is a hollow bar.

I'm pretty sure there's some math to figure it out that I can't find but if I remember correctly a 32mm hollow bar would be equal to a solid bar that is a little smaller.

EDIT: Here's the link to the math showing the differnce between a hollow and solid bar for you geeks out there

Conclusion
Tube torsion members can be used successfully as swaybars with some benefit in weight
reduction.
As an example, 2 individual, rate equivalent (approximately), common sized generic bars
1100mm long with 300mm blades, one solid 24mm the other tube of 25.4 x 3.96mm (1”
x 0.156”) gives a weight reduction of about 2.5kg with about 200g of that as unsprung
mass per wheel.
However the downside to these is the increase in stress levels for equal OD or rate, and
therefore reduced strength. Also the complications seen in manufacture swaybars from
tubular medium, and the importance of geometric control under bending make these more
difficult and expensive to make. The attachment points at the blades can also be a
problem with these swaybar designs.
The additional complications and downsides of hollow bars seem to outweigh their
advantage in overall weight and unsprung mass, which can be seen to only be marginal in
street car application. Even OE manufacturers rarely use this type of design in their
swaybars. However with the right conditions and setups, they can bring some gain in
racing situations, which can require weight reductions to the gram. </TD></TR></TABLE>

you are correct in that...but exactly how much?

I dont know the exact number either. I am trying to figure it out right now. But regardless. A 27mm solid bar is dangerous on the street for a dc5.....

 

juding by that page we would need more specs than just the OD

 

Nice looking bar. I still think the verdict is out if they are legal for Street Touring because of the reinforcement plate.

What do the bars cost, if I may ask?

You are right on that from what I'm reading.

 

look on their site!!!!!

550!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

 

The bar is hollow and the arms have three posititons for adjustment. They are available in .090" and .120" wall. The .090" wall is standard and I beleive it works out to be close to a 26mm solid bar.

There is absolutely no reason you can't drive this set-up on the street.

No drilling required for installation.

 

even a 25mm bar is dangerous for a uneducated driver on the street bro. 27mm bars are actually quite risk enhancing. Im not saying it cant be done. Im just saying unskilled people will likely have the car rotate on them. Of course then again i cant see anyone thats unskilled buying a bar bigger than 22mm...lol

Thanks for the extra specs!!!

i do want to see this thing installed tho...cause there are a ton more holes on that reinforcement bar than there are on a DC5 chasis!

by the way...whats your actualy name....lol... mines Austin Smith...i just kinda was wondering cause of your SN...wondered if it correlated to that name...cause that woudl be weird...lol

My last name is Goldsmith.... AU = Gold

 

damn....lol

a chemistry major such as myself shoudl have caught that

anyway. Have any of these bars sold. I havce a Cusco 25mm solid, so i an not reall yin the market. but i woudl love a comparision

 

I can say with a high degree of certainty that reinforment plates like the one on this kit are not legal in Street Touring.

yeah im pretty sure these arent legal also

 

32mm eh?

Should make a fantabulous daily driver for the youngins

 

DAMMMMMMMMMM

 

i also had the progress...and i switched to the cucso! Its much much better. I woudl advise Cusco cause i have seen ppl complaining trying to find endlinks for the alex bar....appartenyl it doesn tcome with them.

Im not sure i undertand the part about enlink positioning. i havce hotchkis endlinks tho...rephrase that for me and i can answer you!!!

 

New pictures added.

 

i am fairly impressed. looks good

 

alright...i understand now. But i cant tell you how the bars geometry with the stock links woudl be cause i poped my stock endlinks with the Progress bar....sorry i cant help you. I can however supply a pic if you want it....the cusco bar with the hotchkis ends

 

what about clearence for the exhaust. seems like a set up like that will run into some problems. pretty impressive set up, regardless if its too much for the street.

Very good point. It looks like it has less clearance indeed. Looks like people w/ aftermarket exhausts would easily have clearance issues with it.</TD></TR></TABLE>

Actually there is pretty good clearance. We're running a large exhaust on our Grand Am Cup race cars and there is no issue. I'll post some pics of those this weekend.

 

Which GranAm cup RSX will use it ? Just by curiosity ?

Lokks like a really nice piece ! I like that it use a solid bearing instead of a rubber bushing !
