Default Stiffening up the car

Hello all,

A few months ago I bought Ott's rear adjustable drop links. Since I can't find them for the front, where do I go for an alternative? I'm not looking for a track application, just some fun street driving

Suggestions are welcome!

Aryan,

It is pretty easy to make a set of Ott style adjustable drop links. 928 Motorsports sells adjustable drop links and making the part that ahortens the sway bar length is easy just a peice of channel steel that slides over the bar end with some holes drilles into it and a bolt welded to it mount the link. Since you have the the Ott peices on the rear you have the pattern you need. Should not cost much in terms of materials or labor to mane the part.

Carl makes front and rear drop links.....

The million $$$ question is "why are you trying to stiffen the roll bars"....which of course leads to another important ??? of how old are your shocks & springs.....new shocks really transform the way a 928 handles

Hmm I guess I could do that, but then I have to find the right materials - steel grade etc. Keeping it in mind. Thanks!

Thanks Brian. I have new shocks and kept the original springs. Just want to try it out, see how I like it. Just some fun stuff

Note that these will have absolutely ZERO effect on handling, unless the installer goofs up and puts a bias on the swaybar.

Edit: to clarify, these will not "stiffen up" your swaybar or affect your handling in that way -- they will allow you to add or remove bias from the swaybar, that's it.

Perhaps it was the new BFG's also, but since i installed DRs big rear bar, my car has never been so flat and sure footed around corners...or the local round abouts

Im not a track master, but doesnt the sway bar help eliminate body roll...tire lift...and thus effect handling?
cant you tune in and out , to some degree, over/under steer with stiffer bars?

Tony, all the stuff you say about swaybars is true, and it's no surprise that you liked the results. IMHO the best upgrade for any car is better swaybars, or at least something like the Ott drop links that effectively let you dial in a stiffer bar.

The link above points to plain drop links though, and drop links alone do nothing except maybe allow you to adjust left/right bias on the bar. To get the benefits you describe you need a bigger bar or you need a way to alter the pivot points to alter the leverage of the system.

Good call, Dave. That's what I never liked about the 928MS ones (no offense, Carl).
Got the Ott links on the front... looking for a set for the rear. Haven't adjust the bias yet, as I'm waiting to get a better sense of the S4. So right now it's set to minimal preload.

IMHO, the rears are all you need...by tightening up the rear and leaving the front stock, it helps reduce understeer.

Also I had the fronts for a while, and it could cause binding when turning hard right into a parking lot.

you can find something to grab the front swaybar at a closer position to stiffen the front swaybar, right? Just the adjusters wont do anything,but if you can shorten that lever, you can stiffen the front too, as the rear is done with the Ott-carl products. better to buy them as for what, $150, its worth it.

swaybar stiffening alone does a lot on a street car. I remember my old 4 banger in highschool. just the rear swaybar was enough to make the car feel like a go cart!

That was exactly my point. They are good parts, well made -- but will do little on their own to influence handling, only left/right balance(unless you want to drive on an oval track)
