RoW030 vs X74 vs PSS9

I am researching same issues for my '02 C4S, why do you say
that ROW 030 will not enable more neg camber?
my understanding is that any setup that lowers the car should also allow more neg camber.
i'm confused. i thought that it was primarily the higher ride height of the US spec cars that artificially limited the achievable max negative camber.

That would solve all your issues.
Let me know.

Cosmos,
I'm looking for GT3 sway bars, do you have a set for sale?
Cheers,
Stan

I have an '01 C4 with the X74 kit installed. I don't track the car but I have not experienced any problems with the new suspension since the kit was installed almost a year ago. Gert sold me the X74 kit also.

Is RoW030 still agreed upon for the best trouble free from US spec upgrade?
I thought Speed Demon installed X74 a while ago with satisfactory results.
Has any PSS9 upgrade owners experienced problems after install and what is the proper height for mainly street setup?
I will be tracking in the future but given my current time commitment to work, track is not going to be a regular activity.

right on! What is the ride like compared to X74? PSS9 and RoW030s have a softer ride in comparison? given that it is going to be a 90%+ street car for a while, would a GT3 suspension setup be too harsh of a ride?

Never had any issues with suspension. The key for me was to find a shop with experience. We are luck in Seattle in that we have a few great shops one is the engineer for Alex Jobs Racing. Most every track rat takes their suspension projects to him. Bolting the sh9t on the car is easy. Alinement and set up for road, 2 or 3 different tracks and maybe autocross is different. We even get notebooks with different settings for the Motons and sways. Race experience can not be beat. Find the right guy and make sure they stay with you during the adjustment phase. Lastly, it is a good idea to stage the changes. That way you can pin down any issues. Unlike the pros we will have a tougher time articulating the little things to the guy doing the work. It also provides you(me) with a clearer understanding of what the parts do for the car.

First off, I've already done several searches and spent hours learning from previous posts.
I have: a 2000 996 coupe, stock, and I recently purchased Dunlop R compound tires, which was a HUGE improvement. But, I have the neg camber maxed out at around .75 degrees, which is less than any R compound tire wants. Not surprsingly, after 2 track days, the outer edge of the front tires are wearing fast. Also not surprising is that my sticky tires are too much for my stock US suspension and high ride height.
My alignment guy told me that GT3's have different suspension (coil over?), that allows much more negative camber.
I'd ideally like to: 1. lower the ride height, 2. improve handling, 3. enable more negative camber, 4. use OEM parts.
My options are:
1. RoW030, which would satisfy all but #3 above, at a cheap price.
2. X74, which is forbidden by the factory, but will work, and would satisfy my needs, but I'm not sure about the camber issue.
3. PSS9, which would do everything I want, but its not OEM, so its not ideal.
My main question has to do with using the X74 kit. First, can anyone tell me with certainty whether the X74 would allow any more negative camber adjustment than stock?
Regarding the fact that X74 isn't designed for 3.4 liter 996's because of "chassis reinforcement issues"; is it any harder on the car than PSS9, or any other aftermarket upgrade? Obviously, since Porsche doesn't sell those kits, it doesn't have to warranty or recommend them, but since they do sell the X74, they've issued this warning. Is the stress on the car any different from X74 suspension than it is from PSS9?
Has anyone ever seen or heard of a problem resulting from the use of X74 on a 3.4 liter 996?
Does anyone have a 3.4 liter 996 with X74 installed? If so, comments?
Is the GT3 suspension coil over, or is it similar to X74? Or, is it exactly the same as X74?
Any feedback would be appreciated.

Going to a different suspension is different from a camber issue. The stiffer and shorter travel the suspension, the greater the need for camber will be. You typically change suspensions to increase coll stiffness for faster response and change balance for different handlign characteristics. If all you are lookong for is more camber, you shoudl start with a set of camber plates or GT3 control arms.

An issue with the GT3 suspension is that it is designed for a car that is very different than the C2. The GT3 is a much stiffer tub. With that it requires a different suspension. Find a trustworthy local race shop. Their business is dependent on providing you the right solution. We can tell you anything.

Thanks. I am planning to drop my car off with the parts (once I can get the feel for which setup I should get) and let the shop have it for as long as they need to tune it. I never thought this would be so confusing due to the options available.

FWIW - I have PSS9's on the 996. Love the adjustability. In, fact just dropped them to full soft and they are VERY comfortable and compliant on the street. At the other end...full stiff will likely be perfect for track.
