Default Sway bar sizes

I've look around and couldn't find it. Is there a compilation of front and rear sway bar sizes for 993s?
Let's see what's out there:

- Stock C2
- Turbo
- RS (?)
- M030
- M033

Anything else?
Thanks!

Hi Mike,

The definitive answer is in the archives somewhere, as I remember seeing it. But the short (and incomplete) answer is:

F/R
20mm/17mm - US
22mm/20mm - RoW M030
22mm/21mm - RoW Turbo (of which I highly recommend as the best bang-for-buck bars, especailly if you can get them used...IMHO, FWIW)

Someone can fill in the rest...gotta get to work before someone notices

Edward

Ed,

You are morphing into another Viken...great job on the quick response.

I also believe the following is true:

993RS Front 23mm, 5 wway adjustable
993RS Rear, 20mm, 3 way adjustable

Also note some folks have added an extra drop link hole, forward of the stock hole, on the 21mm Turbo bar making it a two (2) position bar. I had this done to my former 21mm rear bar by Andial. I ran the car in the full stiff mode...no under steer here!

Best regards,

OK, two questions. Are US M030 and RoW M030 bars the same? What about US and RoW Turbo bars?

Great, thanks, Viken!!

So... if one would procure a set of US Turbo bars, would one install the rear only, or both?

Well, if you get a set, that's two bars. If you already have a 22 mm front bar, then you'd only install the rear.

Viken, I have a stock US C2, so it has 20/17 combo. I'm about to pick up a US Turbo set, thus thi question. Or should I not?

Not sure what you mean. Are you asking whether or not you should make the swap to Turbo bars? If so, I suggest you consider the consequences. If you are happy with your car now, there is no point in changing bars. If you are looking for less body roll and a slight bit more oversteer, then go for it. Chances are you won't feel much difference, however.

Viken, let's me describe what I have:
20/17 bars, worn out suspension, street-only car, 205/255 tires, understeer.

I have a chance to get a set of 22/19 bars. A set of H7Rs and Bislteins will eventually be on the car along with 225/255 tires. The car will remain purely a street car.

Given all that and my desire for less understeer, should I end up with 20/19 or 22/19 bars? Or should I stay with 20/17?

Ok, I think you might want to throw just the rear 19 mm bar on and keep your 20 front. But, if your suspension is worn out, I'd change that first. Lower the car, give it a good corner balance and alignment specs to suit your needs.

Thanks, Viken, that's what I originally though. I'll try 20/19 once the suspension is replaced.
BTW, a related question - what's the max comfortable spring rate for the street with Bilstein HDs?

I don't know. That's more of a subjective question. What's comfortable to me, may not be to you. I'd say somewhere between 150 and 250? I'm sure the H&R's would be fine.

I would imagine bars such as the TRGs (being much thicker) would provide far greater difference than even the turbo ones. Has anybody had direct experience moving to the TRG from the turbo ones? I have the turbo bars and like them quite a bit yet wouldn't mind removing even more lateral sway from the car (if the difference is significant).
