Anyone interested in an H-sport GB ??

[Stevelev]

I had them on my B6 A4 and the benefit to handling is major. Much moreso than a set of coilovers ... I'm planning on getting them for my car but figured I'd see if there's some interest before going through the paces ...

For info: Click

I know the set costs $392. out of the US and assume a GB would provide better pricing. Post up your thoughts.

Thanks !

Maybe not in the front bar, but definately in the back. I'd be interested in seeing what's available.....

Guys, the H-sports are made to be purchased in pairs (front and back) so if you want just the rear then pick up an OEM S4 or RS4 and save some money. The rear H-sport bar is approx. $220. USD versus the OEM being half that ...

Would it be odd to run the RS4 Rear sway and an Hsport front sway? I ask because I have the RS4 Rear already.

Firstly all H-sports have the same 35mm front bar. I too have the OEM RS4 bar on my car (comes standard on the 2007 S4). I just spoke to someone at Hotchkis for some feedback on the difference in stiffness between their bars as the only info they provide is the difference between OEM and their bars for each car. I suspect that the H-sport S4 rear bar is similar to the OEM RS4 bar (perhaps a bit softer and stiffer depending on the setting) but their engineering department will confirm this soon. With my OEM bars as well as GT Vogts (stiffer rear springs), I still have some understeer when pushing the car and that's with a 40/60 power split (biased to rear of course). Aside from wanting to improve turn-in I'd like to avoid add'l understeer and ultimately end up with some oversteer.

[Stevelev]

I'm still uncertain of the difference in stiffness between the OEM bars and the 2007+ S4's come with the RS4 rear bar ... Here's the info I've been able to obtain directly from Hotchkis:

RS4 H-sports
35mmF and 29mm rear
Front 60% stiffer/ Rear +235%, and +305% stiffer than OEM
90% stiffer than S4 H-sport rear

S4 H-Sports
35mm front and 24mm rear
Front 60% stiffer/ Rear +145% & 215% stiffer than OEM (pre 2007)
30% stiffer than A4 H-sport rear

A4 H-sports
35 mm front and 22 mm rear
Front: +60% stiffer/ Rear: +120% & +150% stiffer than OEM

So.. you're saying there wouldn't be any benefit to adding the front sway bar?

I drove a friends S4 Sedan and when I turn it feels effortless, whereas my car
it feels like I have to battle with the wheel to turn (no not that serious but you get the idea).

If you add the front sway, you will make understeering even worse.

H-sports have hollow-tube design (whereas OEM sways are solid) which makes them stiffer, compared to solid bars of the same diameter.

I was actually saying the opposite but some may disagree. The downside to the stiffer front is it adds back some understeer BUT, it also provides better turn-in. In other words, with the stiffer front the steering response feels more immediate and the front end stays flatter around corners. IMO, the improved turn-in outweighs the reduction in oversteer. I'm assuming that the stiffer rear bar is also used.

Not sure if you're talking about the servotronic steering on the S4 (amount of power assist to steering varies with speed) with quite a nice responsive feel at higher speeds

I'm definitely looking for a better turn in. Maybe I could take the front if someone only wants the back? I'm thinking it wont be as easy to install as the rear though right?

On another note, do the Hsport sways come with adjustable end links?

I believe the front is a bit tougher to install than the rear. No adjustable end links ...

[headshok2002]

On my B5... The front was easier than the rear. The rear had subframe reinforcements which were a PITA to install. Front was a piece of cake, though... I'm sure it's the same on the B6? Get both front wheels off the ground, take off the bushings/brackets, undo them from the C-links... voila. It was very straightforward.

And I went with front and rear on my B5, and was happy I did. Like Steve is saying... turn in is greatly improved, and you'll still have oversteer. The car was completely transformed.

[Stevelev]

^ Thanks for the info ! Yup, B5 had subframe issues and Neuspeed was one of the manufacturers that had reinforcements as part of the rear bar kit ... To the best of my knowledge none of the sway bar manufacturers offer reinforcements for the B6 or B7.

Ack... buying local... good price... so temped. Must... resist... urge.

I believe that set was sold tonight !

[headshok2002]

Haha well that was quick -- and likely for the best!
Too bad it wasn't the RS4 kit, or you'd have had an easier solution to your dilemma!

[Stevelev]

No kidding ! I contacted him as I had this crazy idea that I could use the front and try swapping the S4 rear for an RS4 one. BTW, the RS4 set has not been available for very long.

[CaRtharsis]

Hey, I just purchased an '04 Avant. I'm interested in getting the S4 set if you get a GB together. Let me know.

[RippleChip]

As a heads up, we cannot allow group buys to run unless they are set up and run through an official advertiser. Thanks for understanding.

[Stevelev]

Doubt a GB will happen although perhaps a few of us should go in on an order to save on shipping ...
